Care and use of nineteenth-century gilded picture frames Hugh Glover
This year promises to be exciting here on the campus of the Sterling and Francine Clark Art Institute, where the Center has its home on the slope of Stone Hill. A major expansion of the Clark will open late in June featuring a second building by renowned Japanese architect Tadao Ando. (Stone Hill Center, where WACC is located, being the first.) The Clark’s new Visitor, Exhibition, and Conference Center will provide 42,500 square feet of new space to the museum. In addition, there will be modifications and walkways to the original Museum and the Manton Research Center. Personally, I can’t wait to see the signature Ando water feature, a group of reflecting ponds that will border the new construction. Stone Hill Center will have a David Smith painted sculpture
gracing our lawn, adding additional interest to what is already our “destination building.” As you can see on the cover, I was very fortunate to treat Thomas Cole’s 1827 masterpiece, The Last of the Mohicans,
the exquisite Hudson River School painting belonging to one of the Center’s newest members, The Fenimore Art Museum in Cooperstown, New York. It was an extremely rewarding treatment that I invite you to read about in this issue of Art Conservator. I am proud to say that WACC’s reputation continues to spread. Our success caring for the untreated canvases of mid-twentieth-century artists like Kenneth Noland attracted the notice of the Chrysler Museum of Art in Norfolk, Virginia, as you will see inside. The Center was featured in the Huffington Post this past November as well. In her essay “The Importance of Art Conservation: An Artist’s Perspective” (http://tinyurl.com/md2qt8g), painter Barbara Ernst Prey told HuffPost readers about her participation in a Friends event held here this past fall examining Winslow Homer watercolors.
Finally, I urge you to visit the WACC website homepage (www.williamstownart.org) and click on “Video,” where you can view a promo piece created for the Center by Aaron Taylor. It is exceptional in every way. Aaron, who is a sophomore at Williams College, even managed to make yours truly appear lucid! —Tom Branchick

T homas Cole immigrated to the United States from England while still a boy, and in his new country taught himself to draw and paint. Untutored by formal masters, Cole became the first American landscape painter to speak a completely indigenous
language. His vocabulary was the craggy geography of New England, his grammar the valleys and mountains along the Hudson River, which gave the movement he founded its name. The Hudson River School was this country’s first important art movement, concurrent with the rise of a generation of writers and poets, including Washington Irving, William Cullen Bryant, and James Fenimore Cooper, who were building a unique American literary identity. Cole’s landscapes, which celebrated the splendor of the American landscape, gave visual expression to the ambitions of these men of letters. They in turn welcomed him as a kindred spirit.
In August 1826, Robert Gilmor, Jr., wrote Cole suggesting the twenty-six-year-old artist create a painting with a literary theme. Gilmor, a Baltimore art patron and one of Cole’s earliest and most influential supporters, sought a picture with “some known subject from Cooper’s novels to enliven the landscape.” “Cooper,” of course, was the celebrated author of the Leatherstocking Tales, who that year had published The Last of the Mohicans, his most beloved book. Some months later, Cole visited the White Mountains, where he found the landscape he wished to enliven. The grandeur of the New Hampshire scenery and Fenimore Cooper’s historical novel combined to inspire one of America’s most influential early pictures.
In 1827, Cole produced two versions of Landscape Scene from “The Last of the Mohicans,” the first for Daniel Wadsworth (now in the Wadsworth Athenaeum, in Hartford, Connecticut), who allowed Cole to retain the painting while he made a second rendition for Gilmore. Late that year, the artist wrote Wadsworth, “I have finished the picture for Mr. Gilmore, it is not an exact copy, and I think it is better than yours.”
That second landscape, pictured here, was recently brought to the Williamstown Art Conservation Center for treatment. The Cole is one of the masterpieces of the paintings collection at the Fenimore Art Museum in Cooperstown, New York. The location is fitting. Cooperstown was founded and named by James Fenimore Cooper’s father, and is where the famous writer died and was buried.
It is not clear what Wadsworth’s opinion of the Gilmor picture was, but he nearly swooned over his own painting. “Of the Last of the Mohegans [sic] I can hardly express my admiration,” he wrote Cole on Dec 2, 1827, “[of] the grand and magnificent scenery, —the distinctness of which every part of it, is made to stand forward & speak for itself, with deep gulfs, into which you look from real precipices, —the grandeur and wild Dark masses of the Lower world, whose higher pinnacles only, catch a portion . . . of the soft lights where all seems Peace.” Gilmor was equally delighted with his canvas, praising Cole in a letter, “you convince me by the group of Indians & the individual representation of them,

the area, much like rain will add depth and luster to a black car. The increased contrast emphasized the void between the crisp foreground rocks and the hazy shadowed trees through the opening, dramatically increasing the sense of distance and vast height.
Branchick found working on Mohicans “one of the most satisfying treatments I’ve ever done. It was an opportunity to
present Cole as Cole would have wanted it.” In 1849, James Fenimore Cooper memorialized Cole following
the painter’s untimely death at age 47 the year before. “I know of no painter whose works manifest such high poetic feeling as those of Cole,” Cooper wrote. With Last of the Mohicans, Thomas Cole gave a new voice to American art.
that you are as much at home in figures as in landscape.”The two paintings depict the same scene. From a distance,
we see a ring of people gathered in a mountain clearing, protected on all sides by crags, cliffs, and giant boulders. The summit of a granite mountain rises behind them, and in the distance, a blue vastness of receding peaks, sky, and a distant lake. On closer inspection, the drama occurring among the gathering becomes clear. The men and women in the ring wear the dress of American Indians, while in the center stands a small party of Europeans, including two women, one of whom droops in supplication and distress. The action is drawn from the climax of Cooper’s novel, when Cora Munroe, one of two British sisters taken hostage by a hostile tribe, is compelled to marry her kidnapper or face death. No doubt everyone in the circle is for the moment oblivious to the natural majesty around them, just as the majesty renders the human drama very small.
The difference between the two paintings is the difference between melodrama and tragedy. In the Wadsworth painting, the human action is placed on a flat landing cantilevered off the side of a mountaintop, a proscenium stage ending in a sharp cliff and drop to oblivion. The precariousness of the geologic formation draws the eye to the spectacle being enacted there, reducing the landscape to a kind of backdrop. When Cole redid the composition for Gilmor, he reconsidered the staginess of the first scenario. He depicted the clearing now as a small mesa set in the mountain, bounded by rocks and a copse of autumn trees that tumbles down the slope like a cataract. The peril of the cliff edge is gone from the second picture, replaced by a sublime pathos. In the lower left, to create a sense of vertiginous height, Cole set a gigantic stone leaning over a crevasse, creating an arch through which can be seen the steep, forested side of a distant
mountain. The tops of the trees are in shadow, so you don’t notice them at first. When at last the eye does drift to them, the effect is like the moment when the rollercoaster reaches the top of the first climb and plunges downward.
The converging thrill and anxiety provoked by the passage is one the effects restored at the Center. In all, the new conservation treatment addressed overall condition issues of the paint surface caused by time and outmoded conservation practices from a half century ago. The treatment, by WACC director and head of paintings conservation Tom Branchick, involved consolidation of widespread paint flaking and extensive cleaning and revarnishing. An older double lining, impregnated with wax and adhered with glue, was removed to allow the paint to be consolidated with a synthetic agent —that is, to secure the flaking and rebond the paint layer to the ground. With that step completed and the painting relined, the process of restoring Cole’s brilliant surfaces began.
The painting’s numinous clarity derives from the layers of glaze the artist applied, veils of darker pigment brushed over lighter colors to add depth by variously absorbing and refracting light. These glaze layers are easily susceptible to overcleaning, and some had been compromised by a bygone conservator. Technical knowledge, experience, and a light hand all come into play when removing decades of grime and old varnish, lest the glazes be solubilized by the cleaning solution. The results, however, are magnificent, in the passages of vermilion and yellow in the trees, the greens of the vegetation, the smoky aquamarine of the lichened rocks. Cleaning also brought out the soft modulations of pale blues and violets that enhance the distance of the sky and far horizon.
Branchick discovered that the painting’s pink ground layer [see sidebar, page 7] had gained depth through the addition of a granular substance in the gesso, possibly a fine sand purposely added by Cole, or perhaps merely roughly ground pigment. This grit is evident when seen in raking light, and the rough, subtly uneven surface it creates plays on the paint layer. Each raised grain casts a small shadow and creates a delicate tonal shift. This granularity also adds a dimension of difficulty to cleaning the surface, making it easy to abrade the paint that sits on top of it. Branchick restored a number of areas where the flatness that results from such abrasion had marred the picture’s overall effect.
Grime and discolored varnish had rendered the stone arch an indistinct veil of murk and cleaning alone was not enough to reanimate the original vertiginous effect. To help enliven the passage, Branchick applied an intermediate coat of slow-drying varnish, which served to saturate the darkest passages of

The re-emergence of two Cole studiesBy Sandra Webber
Conservator of Paintings
Compositional oil studies by Thomas Cole recently brought to
the Center for cleaning reveal the artist’s working methods
for his two best-known painting series. The two preparatory
paintings from the collection of Richard Sharp are unpublished.
One is from the painter’s famous five-part allegory of civilization,
The Course of Empire (1833–36), and the other from the first set
of the four-piece suite The Voyage of Life (1839–40). Conceived
in his poetic imagination and based on frequent study trips into
the natural world, both series are imbued with Cole’s desire to
convey moral and religious inspiration to his viewers. Cole had a
nearly photographic recall for landscape, and always reverted to
what he saw with his eyes, not his mind’s eye, stating that “nature
is the sweet guide to correct effects.” Cole was self-taught and
self critical; creating numerous studies and finished versions of
his concepts was common to his working style.
The smaller work is a detailed and polished study for the
second painting in The Course of Empire, titled The Arcadian or
Pastoral State. Commissioned in 1833 by Luman Reed, the series
was conceived to fill an entire wall in Reed’s large home gallery
in New York City. The series follows the growth and decline of
a Greco-Roman empire through many years, all set in the same
location. During the project’s conception, Cole noted that the
repeating setting would be “identified by a striking object, a
mountain of peculiar form, for example.” Indeed, the sharp peak
of the mountain in the left background reoccurs in each picture
throughout the series. Several unused drawing lines visible in
the sketch foreshadow the distant center mountain in the final
Pastoral painting. Only a few studies survive for The Course of
Empire, all on canvas supports of various small sizes. This little
study (6 3/8 by 10 5/16 inches), which reads like a miniature variation
of the large final painting (391/4 by 631/2 inches), is on paper
mounted to canvas. It is very finished, fit for viewing by a patron.
Where the first painting of the series was set at dawn, Cole
described this scene to Reed as “the day further advanced, the
chiaroscuro of a milder character . . . yet fresh and breezy.”
Examination revealed that the Pastoral study was painted
on a salmon-pink ground. Pink grounds were then much in
use by English artists, and Cole, having been born in England,
may have been aware of this choice. He believed landscapes
were best painted on a red ground, “as it gives to the skies and
distance an aerial diaphanous appearance.” In discussing The
Pastoral State he remarked that the reddish undertone created
warmth and assisted with the peaceful composition, in line with
his theories on the correlation of color with mood. The paint
is applied in masterful and fluid, wet-into-wet brush strokes
with no alterations, and appears to have been executed in one
sitting. Sketchy graphite underdrawing, visible to the unaided
eye in the sky, outlines the mountains, clouds, and trees. An old
ink inscription on the lower brown paper tape on the stretcher
reverse appears to be in Cole’s handwriting, and reads “Study
for [2nd] picture of Course of Empire by Thomas Cole.” This
suggests the original mounting to canvas was done in Cole’s
lifetime, possibly at his direction, and probably to secure three
small tears along the top edge. The picture was cleaned of two

Feature
W inslow Homer’s brooding nocturne Moonlight reveals an artist growing ever more confident in his artistic ability, and perhaps as well a man in the
midst of courting the lost love of his life.Homer was in his late 30s when he created the 1874
watercolor of a seaside couple beneath a full moon and trailing clouds, at a point in his life where his early career as a magazine illustrator was giving way to the life of a mature artist. As scholar Martha Tedeschi observed, Homer had “inaugurated his career as a serious watercolorist with stunning suddenness” just a year earlier, in late June or early July 1873, when he arrived for the summer in Gloucester, Massachusetts. Over the next three decades, he became America’s undisputed genius of the watercolor, an elusive, evocative medium of gesture and light.
A decade before, he had turned down a position as staff illustrator at Harper’s Weekly to pursue the independent life of a freelancer, and during the Civil War had recorded the camps and battle lines of the Union Army for Harpers. The work made Homer’s reputation as a chronicler of American life and launched his career as an oil painter as well. Back in his
New York studio, his ambitions widened, from the anecdotal storytelling of illustration to increasingly complex genre scenes in which literal narrative gave way to psychological ambiguity and subtle, luminous depictions of light.
Homer found an occasional tutor to instruct him in the basics of oil painting and learned the rudiments of watercolor from his mother, a devoted amateur. Beyond these fundamentals, however, he taught himself advanced skills through repeated and tireless trial and error. He is one of a very small number of painters to achieve mastery in both oils and watercolors.
In watercolor especially, Homer’s eye and hand achieved moments of sublime brilliance, a fact clearly seen in the collection of the Arkell Museum in Canajoharie, New York, which holds sixteen of his watercolors on paper, including such early efforts as Moonlight. Fourteen of the paintings arrived at the Williamstown Art Conservation Center’s paper lab for examination and reframing in advance of a forthcoming catalog and exhibition at the Arkell. The treatment offered chief paper conservator Leslie Paisley the opportunity to study Homer’s painting technique and learn something of the master’s work

Winslow Homer, Moonlight, 1874.
process. Her treatment report affords a look over her shoulder and through the microscope as she inspected Moonlight:
The composition was laid out with a faint pencil sketch over which colored transparent washes were applied wet onto damp paper. The technique in the sky involved colored washes applied to damp paper.
Homer typically used a handmade, heavyweight watercolor paper with a slightly textured surface and pale cream color.
The particulates from the pigment collected in the interstices of the paper creating a mottled sky upon drying. More than two washes are visible in the sky. Additional watercolor washes were applied to the foreground as dark shadows and light highlights that were added with opaque watercolor. Washes were allowed to dry before layering. The opaque media on the figures was applied last.
Perhaps the most notable aspect of Paisley’s examination is evidence that Homer used a resist to create some of the light effects in the painting’s dramatic sky. A resist is a waterproof material used to protect selected parts of the paper where broad, often darker washes are applied; the technique is used typically to create highlights and passages of lighter tones. After the wash is dried, the resist is removed with a small knife, revealing the white of the paper (or a lighter underlying wash) beneath it. Resists are a standard element in the watercolorist’s toolkit, and Homer used them regularly. But as the Moonlight treatment inspection reveals, there is always something new to learn about how artists work:
This watercolor has some very interesting features. The white deposits in the foreground in the form of angular white three- dimensional specks deposited in the wash are residues of a “resist” Homer used to create highlights while painting. These specks were examined under the microscope and appear to be identical to those found on seventeen of the twenty-nine watercolors found in the Art Institute of Chicago collection. Conservators there proposed that these may be residues of a resist (composed of lead white, drying oil and resin). . . . Homer’s brother Charles graduated from the Lawrence Scientific School at Harvard University and specialized in the chemistry of color. Conservators at the AIC [Art Institute of Chicago] speculated that Charles may have helped Winslow formulate the resist while employed by the Valentine Varnish Company. The fact that this resist was found on a work this early is something that [earlier experts] had not found. They assumed that the use of this resist was something he learned in England.
Homer spent 1881 and 1882 in London and the English
coastal village of Cullercoats. The period resulted in a profound maturing of his imagination and style, as Homer absorbed the long tradition of British watercolorists, climaxing in the bold paintings by J.M.W. Turner. Upon Homer’s return to the United States, critics immediately noted the added dimensions of his technique, which one writer described as “more skillful, more refined, more delicate.” But as Paisley discovered, some of this technical prowess had developed before Homer sailed for Britain:
Certain areas of the sky and sea spray where the clouds are lighter than surrounding sky may have been achieved by either wet lifting (using a clean wet brush to paint back into the wash to lift newly deposited color) or by the application of a resist that would have prevented saturation of the sky as darker washes were added. A combination of these techniques may have been used. Homer also blotted the foreground sand to interrupt the uniform wash and create more texture. One can also clearly see where he dragged his loaded flat brush across the damp paper in the left edge to help disperse the drying wash.
One factor to support the possible use of a resist is the fact the paper in some areas of cloud and sky appear slightly abraded which could have occurred when the resist was removed. That and the crisp edges of the lighter area suggest there was a mask of some kind to prevent over-darkening of the sky. The areas of sea spray may also have been reserved with the use of a resist as the paper in this area had many layers of wash applied to create a mottled sea.
If resist residues were not completely brushed off of the paper surface before continuing with washes, they would have become bound into the foreground wash. The effect appears almost intentional however as it creates “holidays” in the wash that resemble the sparkle of sand at an angle.
Those sparkling sands are among the elements that create Moonlight’s air of romance. But pensiveness, almost a melancholy, marks the courtship as well. In the late 1870s, Homer made a number of portraits of beautiful but “emotionally unavailable” women that Tedeschi conjectures may indicate “evidence of a failed romance, perhaps even a rejected proposal of marriage.” The Arkell painting may reveal not just the foundation of the painter’s technical sophistication, but the roots of his emotional depths as well.
Winslow Homer: The Nature and Rhythm of Life opens at the Fenimore Art Museum in Cooperstown, New York from June 6 to August 24, then moves to the Arkell Museum, Canajoharie, New York, September 2 through January 4, 2015.

Acrylic paints were introduced as an artist’s medium in the late 1940s and instantly opened
new avenues of creative possibility. Acrylics dried quickly and came in a vast palette of colors, including
new synthetic hues that trumpeted modernity. Unlike oils, acrylic emulsions could be applied directly to raw canvas, no small
philosophical matter in an age of “paint as paint,” when the aim was to remove the artifice from art. Kenneth Noland was one of the pioneers
of the age. In the 1950s and ’60s, he devised innovative ways to exploit the new paint and experimented endlessly with the conventions of the four-square
frame. One solution was to rotate the square into a diamond, transforming corners into points and repurposing the painting into a banner, sign, or decorative object, as
seen here in his 1965 Blonde, from the collection of the Chrysler Museum of Art in Norfolk, Virginia. The painting, with its nested chevron shapes, was brought to the Williamstown Art
Conservation Center for cleaning and remounting. Lignin in the stretcher had discolored the edges of the canvas (not unlike the yellowing of newsprint), and the unprimed cotton had oxidized and become
dingy, neutralizing Noland’s brilliant, harmonically complex color fields. Chief paintings conservator Tom Branchick has perfected a method for cleaning the untreated canvases of mid-century modernists like Noland;
his technique returns the support to its original brightness without compromising the painted surfaces. “Hard as it is to believe, raw canvas is difficult to treat,” said Chrysler curator Amy Brandt, explaining why the museum sought out
WACC. The renewed painting will be on exhibit when the renovated and expanded museum reopens in May.

Monument to Comrade Picasso was among the last
works by the Ukrainian avant-garde artist and designer Vasyl
Yermylov. Active from 1911 to 1968, Yermylov studied under
Ilya Mashkov, Pyotr Konchalovsky, and other artists associated
with the cubist “Jack of Diamonds” group at the Moscow
School of Painting, Sculpture, and Architecture. His own art
was a synthesis of several artistic streams, taking cues from
expressionism, cubism, futurism, and neo-primitivism. In addition
to paintings, assemblages, and sculpture in a variety of materials,
Yermylov was a prolific designer, creating textiles and interiors
for the Kharkov Pioneer Palace, as well as book illustrations,
advertisements, and propaganda posters.
The painted wood sculpture, one of two such “monuments” by
the Soviet-era artist, arrived at the Center exhibiting numerous
minor structural insecurities, cracking and lost paint, and a
surface discolored overall by a coating of ingrained dirt and
flyspecks. The most striking feature of its pretreatment condition,
however, was the advanced
degradation of the polymer film
that enclosed the tower. The
film was nearly opaque, with a
dull yellow color that completely
obscured the colors and details
within the tower. It was highly
embrittled and split easily when
handled. From the characteristic
vinegar odor that came from the
piece and the results of testing,
the polymer was identified as a
cellulose acetate.
Treatment included cleaning,
repairing splits and cracks in
the internal plywood structure,
consolidation of cracking paint,
fills, and inpainting. The degraded
polymer on the tower was removed
and saved for curatorial purposes. It was then replaced with
Mylar of an approximate thickness to the original, wrapped
around the sculpture the same number of passes and secured to
the outside of the tower using the original nails as possible.
Besides leaving the object structurally and chemically
stable, this treatment revealed the lively Easter egg colors and
architectural details within the tower that were impossible to
appreciate before, and restored the original visual contrast of the
glossy and colorful tower against the textured matte planes of the
surrounding structure.

On the eve of the American Civil War, Watkins Banks wore
this dress-uniform cutaway coat as a member of the
Columbus Guard, an active local militia in western Georgia,
along the Alabama border. The Columbus Guard dates to 1834
and attracted many young men from prominent families in the
community, Banks included. They were known for their brilliant
red dress uniforms and must have cut striking figures as they
drilled. In 1861, with the Battle of Fort Sumter, community militias
both in the South and in the North were called to join their
respective armies. During that year, Banks wrote his name “Wat.
Banks” and “1861” on the inside lining of his coat. Sadly after
three years of fighting Banks was killed in combat in 1864. But
his dashing dress coat survived in the possession of his family
for more than a century and a half, and will soon be on view once
more in Banks’s hometown at The Columbus Museum. Before
going on exhibit, the coat was examined and received major
treatment to stabilize and integrate its components.
Red with white trim and raised gold braid, the coat is entirely
hand-constructed with fine silk stitching, hallmarks of well-
tailored nineteenth-century men’s garments. The coat is made
from red and undyed wool fabric woven in a 2/1 twill weave
pattern and “fulled.” To full wool, the nap of the fabric is raised
and trimmed smooth, giving the appearance of felt. The coat
has a quilted cotton lining, stuffed and shaped with horsehair
to impart a smooth, trim profile that provided the wearer with a
formal dress silhouette. The stand up collar and the center front
of the coat close with hooks and eyes. Covering the entire front
of the coat is an undyed wool bib that buttons onto the chest with
eighteen brass buttons, arranged vertically nine to a side.
Although the survival of the coat is remarkable, it arrived at
WACC in an exceptionally delicate condition. The construction
threads are fragile and many of the seams were actively splitting.
The armpits of the coat lining were in an advanced state of
deterioration, evidence of its use. In these areas, the fabric was
discolored, stiff, and brittle. The lining was so degraded and
imperiled that the coat could not be mounted on a mannequin
for display. During its lengthy storage, perhaps fostered
by the moist Georgia environment, protein-eating insects
found the coat an ideal food source. They ate their fill,
roughly ingesting a quarter of the wool fabric, leaving
behind a lacy network of losses. What remained of
the fabric was vulnerable to tearing and loss. Most of
the buttons were cut from the coat to serve as family
mementos including the eighteen buttons that once held
the bib to the coat front. Four detached buttons were
delivered with the coat and another two were reattached
to the base of each coattail.
Charged with stabilizing the coat so it could be
exhibited and to insure its long-term preservation, the
treatment drew on a wide range of techniques from
the conservator’s tool kit. Much of the stabilization and
integration of the coat was performed with standard
techniques common in textile conservation. The split
seams and insect holes allowed access to the interior
layers of the coat, which permitted a red cotton interlayer
to be inserted and serve as a stitch support for a fine
bobbinet overlay, a near-invisible nylon mesh that covers
and reintegrates the fragile original fabric. The two new
layers disguise many of the losses in the red fabric. To
treat the armpits of the lining, stitching was combined
with modern adhesive techniques. The fabric at each
armpit was humidified, repositioned and reinforced with
a light adhesive-coated sheer fabric. The light tack of
the conservation-grade adhesive, combined with sparse
stitching, allowed the underarm lining to be reintegrated.
Soft arm supports may now be inserted into each sleeve
and integrated to a mannequin torso to support the arms
of the coat while on display. Replacement buttons were
cast in epoxy with stainless steel shanks and painted to
look like the brass originals. For a brief time, WACC was
the center of brass button manufacture for the Columbus
guard.
This unique piece of history is now on display at the
Columbus Museum. The staff at the Museum hopes
additional Columbus Guard artifacts, from its earliest
years through its disbandment after the First World War,
will emerge from other families.

WACC News & Notes
I have often found myself pondering the unusual pleasure
that an unfinished portrait supplies. I am a fan of portraiture
in general, and as much as I admire a landscape—and I do—I
have always found the landscape of the human face as lovely, as
engaging, and as compelling.
Every portrait tells a story, at times about the artist, at
times about the era, and (perhaps most satisfying), at those
times when it reads out the character and life of the sitter. I
am certain every museumgoer has shared that experience of
“meeting” an individual on the gallery wall—a face, a gaze, a clear,
almost shocking, connection between viewer and subject that
somehow defies the two dimensions of canvas and paint, arcing
a connection between the present existence and a past life that
feels real and triggers unexpected and powerful emotions.
To these satisfactions (addictive satisfactions for me, as I
never tire of meeting new paintings), an unfinished portrait adds
an extra dimension. To an intimate and satisfying glimpse into a
sitter’s character, the unfinished portrait adds the bold invitation
to enter the process of the artist’s mind. It allows us to step inside
the artist’s process midway, and see not only where it ended, but
how it started and went on to achieve the magic that is a portrait.
The unfinished painting does more than invite us to admire
and decipher the artist’s technique, though. It makes us an active
third party (for every portrait is composed of three people, the
artist, the sitter and the viewer), completing what the artist left
off and plotting a new trail from there. In a way that a finished
painting cannot, the unfinished portrait remains an open process
begun again by every viewer who wanders into its landscape.
The most stunning portrait I’ve seen at the Center in the
past year was a small, virtuoso Portrait of a Woman by Howard
G. Cushing. Cushing, little remembered today, was a Gilded-
Age American painter, friend of Whistler’s and renowned for his
arresting portraits, many of women. His skill was evident in the
portrait I saw. The vivid, intent gaze and self-possessed, almost
willful expression of the sitter seemed to leap from the canvas,
rendered in short brushstrokes and an impressionist palette. I
became extremely curious about the artist and his technique and
marveled at how the effects were achieved. So it was a grateful
coincidence when two portraits by the same artist arrived for
treatment on my workbench at the Center. Unfinished portraits
this time, they were like a primer on the artist’s process.
One might think the unfinished quality would detract from
the illusion of a likeness, the suspension of two-dimensions,
but in fact I find it the opposite. It’s like tracing the spark of life.
Unfinished portraits have a Galatea quality, when, like the famous
sculpture Pygmalion brought to life, you see both the artwork’s
two dimensions of substrate and brushed color and the sparkle
of human personality emerging from the canvas. Granted, an
unfinished portrait can be jarring as well, and the charm or the
dissonance depends as much on the viewer as the object. But
even in cases where they simply look, well, unfinished, the wealth
of detail revealed in the process remains rewarding.
The two Cushings are executed on a bare, off-white priming
layer. There is a minimum of pencil sketching visible below and
around the paint—making it clear the artist moved very quickly
away from the perfunctory, loose graphite sketch to his finished
and evocative mosaic of tiny brushstrokes. The faces are very
complete, and their placement within the composition makes it
clear the artist intended bust-length portraits. The fact that the
portraits were completed before anything else was even blocked
in makes it clear that for this artist the faces
were not just the focus but the fulcrum of a
portrait. The eyes and surrounding features
are worked up with great detail; the transition
to unpainted areas is sudden and shocking,
with just a few looser strokes in the silhouette
of the hair to mark the transition. The Galatea
effect is perhaps a few more strokes away in the
woman’s portrait than the man’s. For him, the
vivid, almost electric short brushstrokes of color
have begun to work their magic, bringing to life
his eyes and character, inviting us to continue
his costume and posture in our mind’s eye.
The woman is perhaps a little less accessible,
but we are left with clues of age and hairstyle
that might suggest a costume, a posture, and
the preoccupied look that suggests her mind
is elsewhere and only partially committed to
sitting still for the painter.
The privately owned paintings have come to
the Center for cleaning and stabilization of paint
layers. The background is heavily grimed and
has some spots of mold and water damage. The
paint is applied in distinct short brushstrokes
in a dry technique, that is, with a minimum of
media to keep the strokes distinct and largely
unblended. Because of this, the
paint is slightly underbound (that
is, lacking in media or binder) and
consequently as friable as pastel,
especially at the edges of the
thinnest application. The friable
paint will be consolidated and,
stroke by stroke, gently cleaned
with a mild water-based cleaning
solution; the worst of the grime
and dust will be removed from
the background and sealed with a
matte or semi-gloss varnish layer.

A World ApartJohn H. Finley, editor-in-chief of the New York Times, gave this
eighteen-inch globe to the American Geographical Society in 1929,
and began the tradition of inviting explorers and aviators to draw and
autograph the routes of their adventures. The eighty-plus signatures
on the “Fliers and Explorers Globe” have created, in the words of
the Society’s website, “a priceless and unique symbol of humanity’s
. . . drive to explore the universe.” Among the famous and intrepid
to leave their mark are Charles Lindberg, Neil Armstrong, Edmund
Hillary, and Amelia Earhart — twice (see detail at right). The globe was
brought to the Center for minor repairs and stabilization of the paper
map layer and plaster substrate. New signatures are added every four
years, most recently in 2012.

By Heather Clavé
M any French expatriates who come to the United States
don’t expect to stay, but do. Then there are those who
know that their time here is limited. Much like life, what they
do with the time they are given will dictate the richness of their
experience. For paintings conservator Thierry Boutet, a native
of the Paris region, there was only one option. He was not going
to waste a moment. It was the four-year work assignment of his
wife, Virginie, that brought Boutet and his family to Atlanta in
August 2010. His English “was crap,” as he put it, but he had a
skill and, above that, a passion for art conservation, one of the
most specialized fields out there.
Boutet discovered his path relatively late. Born to a working-
class family, he loved art and went on to earn a degree in visual
art from the Sorbonne. While working at the Louvre Museum
in Paris as part of his doctoral program, his attention moved
from studying the work of the masters to wondering about the
process of maintaining them for future generations.
“It’s good to work for a painting,” said Boutet, his brown eyes
glowing with intensity as he described the details of his work.
“You need to know the essentials of painting to preserve the
property. The technical aspect is essential, but you can’t forget
that it’s a work of art. You have to be faithful to the idea the
painter had when he painted it. Even if the creative aspect has
disappeared, there is still a connection to the visual arts and the
same reflective process and analysis as with creation: How do
you conserve the painting so that it lasts another eighty years?”
Eighty years, Boutet explained, is the normal duration of any
given restoration.
Doors opened for Boutet, and his doctoral thesis went
unfinished. He discovered he preferred the more hands-on
approach of conservation to the academic pursuit of art.
He did a three-year educational program in paintings and
polychrome artifact conservation with the Atelier du Temps
Passé; then an internship with the Institut d’Art Conservation et
Couleur, working with Madame Brans, one of France’s leading
conservators. Afterward, he got a coveted spot with the Atelier
Laquèus, where he developed specialized knowledge in the
restoration of furniture and lacquered art objects from China and
Japan.
All during his studies, his sweetheart from high school was
with him. “We met in ninth grade and have been together ever
since,” Boutet explains of his wife Virginie, “seventeen years.”
She helped him through his education and training, and when
it came time to help her fulfill her own dreams in the Foreign
Service, there was no hesitation.
“As they say, you have to go out and see the world to know
what you have at home.”
With their young son, the couple moved to London, where
Boutet soon landed a job with one of London’s top conservators,
working on high-profile portraits and paintings. Other jobs
followed, which gave him further experience with lacquer work.
Then the 2008 economic crisis hit, requiring Boutet to get
creative in his approach to employment.
“You have to work at your craft every day. Going to museums,
galleries, auctions,” he said. “Otherwise you lose your skill.”
This tenacious spirit proved to be a tremendous asset when
the family arrived in Georgia. With portfolio in hand, he knocked
on the doors of every museum, gallery, and auction house.
“I’ve always done that,” he says. “[Conservation] is my
passion. I live for that. But I had a warmer welcome here.
Americans give you a real chance.”
He did his homework and discovered the Southeast’s largest
conservation facility, the Atlanta Art Conservation Center
(AACC), an affiliate of the Williamstown Art Conservation Center
in Williamstown, Massachusetts, and Atlanta’s High Museum of
Art. The weekly visits began.
“He kept coming by, but didn’t really push us,” said Michelle
Savant, Conservator of Objects at the Atlanta Art Conservation
Center. “It was always, ‘The little French guy came by again.’
Then one day he came and didn’t even ask about a job. He just
sat, watching me work and chatting away. When he left I asked
Larry [Larry Shutts, Conservator of Paintings and manager at
AACC], ‘there’s gotta be a way to keep this guy.’” Boutet was
hired part time.
Around the same time, the Atlanta Art Conservation Center
had landed a major project restoring the famous Talledega
College murals of the “Amistad” uprising by Hale Woodruff
[Art Conservator, Spring 2012] before a three-year tour to
museums around the country. These huge murals were in their
original state, and conserving them for the first time was a
major undertaking that required extra help. Boutet’s part-time
work quickly escalated to extra hours. At times, he became
so engrossed in the work he would forget to eat lunch. His
colleagues were impressed with his rapidity and precision, and
soon he was taken on full time as Assistant Conservator of
Paintings.
In this capacity, Boutet has had a rich encounter with the
Southeast, having had the opportunity to meet and work with
prominent public and private collectors of the region.
“It’s very gratifying work, especially here in the South where
people are so friendly and warm. For me, the salary is in the
smile.”
Boutet confesses, of course, that the “French touch” doesn’t
hurt in his interactions with Southerners. “Once, I was even
invited over for homemade scotch in Alabama as a thank you.”
Now in their final year in Atlanta, Thierry Boutet and his
family have made a comfortable niche for themselves. Family is
top priority, and so Thierry and his wife make sure that their son,
Dorian, is well adjusted and well connected to friends and family
in France. With the same tenacity and analysis that he applies
to his work, Boutet researched schools for Dorian to ensure the
best education possible, supplemented with the French scholastic
offerings of the Ecole du Samedi. In addition to experiencing all of
the sights and sounds that Atlanta has to offer, Thierry still takes
time to do art on his own, and is pleased to see that his son loves
it, too.
As with any job in the Foreign Service, the family will soon
move to their next location. Ever mindful of their son’s education,
Boutet and his wife hope to be stationed in Europe to be close
to family, or an English-speaking country to solidify Dorian’s
unaccented English. Naturally, having landed the job at the
Center, it’s hard to let go.
“If I could take anything with me, I would pack these two in my
suitcase,” said Boutet, pointing to Savant and Shutts, who clearly
are not happy at the thought of Boutet and his family leaving.
“Where will we find another French guy to crack jokes with?”
lamented Savant.
What advice does Boutet have for newcomers? “When you
know you’re only here for a limited time, you’ve got no time
to lose. Don’t hesitate to meet people. Go on site. Do your
homework on the people you’re dealing with. Provoke the
encounter and don’t let go.”
Words of wisdom from someone who knows what he’s talking
about.

Care and use of nineteenth-century American gilded picture framesBy Hugh GloverConservator of Furniture and Wood Objects
Overview
Picture frames are a standard component of museum collections and subject to wear and tear in their functional role surrounding paintings. Damage to frames occurs during exhibition, storage, and travel, the result of handling, hanging processes, adverse environments, neglect, and irreversible restorations. Picture frame maintenance is an important but sometimes overlooked aspect of collections management. Frame preservation has only rarely been addressed.
Curators and collectors today are increasingly interested in identifying original, or first, picture frames on paintings. The date of frames can be assessed from their style and manufacturing technology, while shared marks on the stretcher and frame backs can indicate whether a frame is original. It is possible, therefore, to sometimes use the frame information to assist in dating a painting, another important function of the preservation specialist. This article describes some of the fundamental considerations stewards of nineteenth-century gilded frames should understand to best maintain their collections.
Environment
Gilded wood objects are very sensitive to environmental conditions and they are probably more sensitive than most paintings. Gilded wood in adverse climates experience detachment and loss of gilding/ornament, while the accumulations of grime lead to surface darkening and cleaning campaigns that may well cause damage.
The bright gilding that survives on frames housed in shadow boxes of the second half-century illustrates how less well protected gilding has now been altered by grime, abrasion, and staining from skin moisture and grease.
Handling
All gilded objects should be handled with non-marring gloves to avoid abrasions and staining. In practice, however, gilded frames are still handled with bare hands as the frame is considered a safe means of handling the artwork. Other handling precautions include prepared soft support pads, not lifting empty frames by the thin sight edge, and avoiding contact with loose parts . Labeled Ziploc-type bags are useful for saving detached parts.
Dusting
Occasional dusting of frames with a clean soft brush and vacuum is recommended to remove dust that would otherwise become grime and attract moisture [Fig. 1]. Light-weight dust covers can help in dustier storage areas, e.g. clear 0.35 mil polyethylene. Even a seemingly simple procedure like dusting is best done by someone with experience.
brown layers of natural resin, streaky with vertical brush marks
and fracturing from age. Black grime layers and bronze paint
overspray, probably from an amateur frame repair, added to the
pre-treatment darkness.
The study for Manhood, the third of four images in Cole’s
The Voyage of Life, is quite similar to two of the three known
compositional studies for this scene. Painted on a thick wood
panel with a pink ground layer, the reverse appears to have
been used as a palette, probably a cost-saving measure by the
financially strapped artist. It is most similar in size and layout
to the study at the Munson-Williams-Proctor Arts Institute
(MWPAI) in Utica, New York, also on wood, and another on
academy board at Smith College Museum of Art in Northampton,
Massachusetts. Many figural
drawings and oil sketches
from this scene also survive,
suggesting Cole struggled
more with the figures than
with the landscape elements.
The Voyage of Life, initially
commissioned by Samuel Ward,
evolved into four very large
paintings done in two complete
sets, the original set now
owned by the MWPAI. This first
set’s final Manhood is 52 by 78
inches, which is proportionally close to the sketch panel’s format
of 111/4 by 17 1/8 inches. The second set, completed in 1842, is in
the National Gallery of Art in Washington.
This Voyage of Life study is very broadly and fluidly painted,
and the landscape and weather depictions are bold and
dramatic. There is less underdrawing on this study, no visible
alterations, and the lower right corner was left unfinished. Cole
was proud of the speed at which he could complete even his
larger works, so studies like these were probably executed very
rapidly. Despite its larger size, it does not have the finished
appearance of the Pastoral study for The Course of Empire. Cole
once described oil sketches done all at once as “never more than
half true,” likening them perhaps to dead-coloring, the first layer
of paint for an image, which often looks flat until more layers
deepen and brighten the colors. The Voyage of Life series, even
in its final execution, is more dynamic in mood and movement
and less fussy than the earlier Course of Empire. This may be the
natural result of the different subject matters or may reflect some
evolution of the artist’s approach, or both.
The Manhood study arrived with a coating of heavy black
grime interspersed with reddish shellac on top of a brown
coating containing linseed oil. It is unlikely that either coating
was applied by the artist. The shellac, a furniture coating not
recommended for pictures due to its natural orange color, had
darkened to a hot brown, causing the painting to appear too
warm in tone. Both the shellac and the underlying linseed oil
layer were sloppily applied, leaving thick patches on the surface.
Cole understood the value of waiting prior to applying final
coatings and recommended only one thin layer of varnish be
used on his pictures.
Both oil studies are now ready for proper viewing and can
be better assessed and compared for integration into the body
of Thomas Cole’s work. They are valuable additions to the
understanding of the artist’s technical skill and processes. The
compositional study for The
Voyage of Life will be included
in an upcoming exhibition
catalogue of Cole’s famous
allegorical series, where it will
be discussed in the context of
Cole’s other Manhood studies.
The traveling show will
be centered on Munson-
Williams-Proctor Arts
Institute’s suite of four Voyage
of Life paintings. Thomas Cole,
who mused in prose, poetry,
and paint about the relationship of color to musical harmonics,
would surely have been pleased see to see his original
compositions re-emerge from their dark, encrusted surfaces.

subject to loss. Surviving labels can be protected in place with an overlay of five-mil Mylar attached with double coated tape (3M 415) on a barrier layer (B72), and detached labels can be encapsulated in Mylar.
Exhibition labels have traditionally been placed on frame and stretcher backs. A less intrusive and longer lasting location is on the painting’s backboard encapsulated in Mylar, or placed in the owner’s records.
Modern inventory marks are applied between soluble varnish coatings to a discreet part of the frame, usually an outside corner and/or the back. Troublesome old inventory labels include gummed paper on water gilding, and pressure adhesive labels or masking tape on oil gilding.
Gilding that has been covered with a title plate is usually better preserved than adjacent surfaces and indicates an earlier condition. The silhouette revealed when plates are removed may need to be masked with pigments. The introduction of new title plates will eventually result in the same irregular coloring to the gilding.
Rebate modifications
Frame rebates are sometimes modified to improve the fit of a painting. When an aperture is too large to neatly and safely house a painting, the sight size can be reduced by fitting flat or L-section wood slips (or a liner) within the rebate. Mitering the ends of the slips is often sufficient to hold them in place, rather than adding fasteners or adhesive. L-section slips can double-serve by also centering the painting. Whether to only paint the reveal of the new slips, include a cavetto profile, or gesso and gild the reveal with oil or water gilding, depends on the frame’s existing gilding quality and the extent of the reveal. Linen covered liners were popular in the second half of the twentieth century and they can be original to a twentieth-century frame, but they are a later addition to a nineteenth-century frame and were added to modify the sight size.
A keyed-out stretcher or a larger painting can require the widening of the rebate. Wood may need to be removed with a sharp chisel or router, although this obviously involves the loss of original material and detail.
Strips of felt tape with an adhesive backing (e.g. Decco tape) are now generally fitted to rebates to cushion the edges of the painting. Attachment of the felt is improved by first dusting the rebate with a brush, and/or coating it with thin varnish (e.g., B72, shellac).
Glazing
Glazing is added to frames for the protection of artwork, generally for specific exhibitions and travel. Modern glazing materials are lightweight thermoplastics (acrylic or polycarbonate) or heavier-weight laminated glass, and most have proprietary coatings to reduce UV light and reflection. Glazing is fitted in the rebate (or in front of a liner) and is backed with dark-colored and felted wood or acrylic spacers. The increased protrusion of the painting in the back can be enclosed within an added build-up.
Microclimates
Sealed microclimate enclosures are used to stabilize environmental influences during exhibition and travel. The history, development, and design of various enclosures have been described in recent literature: e.g., Kamba (1993); Richard (1995); Wadum (1995); Sozzani (1997); Phibbs (2002). The painting is enclosed behind glazing within the frame (or travel frame), and larger vitrine enclosures can also include the frame.
Over-zealous dusting results in progressive abrasion that removes the gold and reveals the bole and gesso preparation layers, and varying degrees of this condition are very common. An aqueous cleaning results in the removal of water gilding and its toned coatings, and this is also a common condition.
Hanging hardware
The common early nineteenth century hanging device was a ring and screw combination located singly or as a pair in the top rail. Simpler early devices included wire, leather, and sheet metal loops, located in the top rail, while some rural portraits were not framed and the loop
device is found on the stretcher. Paired screw eyelets located in the side rails were popular after about 1825 [Fig. 2], and heavier frames could have custom hardware.
Modern practice is to fit steel strap hangers (D-rings) for hanging, Oz-clips for some crating, and mending plates for securing the artwork, mostly with pan-head sheet-metal screws. Secure fittings reduce the incidence of repeated screw holes, however, events can lead to new holes in the frame and stretcher backs, and care is necessary to avoid excessive holes or obscuring historic evidence. A direct-reading caliper is useful for optimizing the length of screws added to a frame. Redundant early hardware can be preserved on the frame, or separately if necessary.
A heavy-duty hanging scale was used to crudely measure the failure point of a common strap hanger with a stand-up wire loop (item U711, United Manufacturers Supplies Inc.). The wire loop failed by unwinding from its strap at around 520 pounds, despite the strap being fixed with only small screws in softwood. With safety margins that include an allowance for one hanger to temporarily hold the whole weight, perhaps 150 pounds is a reasonable maximum loading for a pair of these hangers. Most framed paintings weigh less than 150 pounds, even when they are fitted with laminated safety glass. A record of the weight of heavier objects can be useful, as would further load tests of hanging devices. Old braided steel wire corrodes and becomes brittle and should be replaced with a stainless type. A single wall fixing combined with a connecting wire on the back of the frame is less secure than two wall fixings, with one for each strap hanger. Failures within the hanging arrangement can be disastrous.
Labels
Frame makers can be identified from the occasional inscriptions found on the frame back. These can be printed paper glued on the wood, pencil inscriptions, and late-century marks applied by carving, ink stamp, and engraved metal coupons [Fig. 3]. A selection of late century marks are illustrated by Smeaton (1988), and many New York and Boston makers have been recorded by Katlan (1987). Other frame back inscriptions record dimensions, style, owner, and hanging location, etc.
Ideally, owner records include copies of maker’s labels/marks since they are fragile and

Mission Statement
T he mission of the Williamstown
Art Conservation Center, a
nonprofit institution, is to protect,
conserve and maintain the objects
of our cultural heritage; to provide
examination, treatment, consultation
and related conservation services
for member institutions, and for
other nonprofit organizations,
corporations and individuals; to
conduct educational programs with
respect to the care and conserva-
tion of works of art and objects of
cultural interest; to participate in the
training of conservators; to promote
the importance of conservation
and increase the awareness of the
issues pertinent to collections care;
and to conduct research and dis-
seminate knowledge to advance the
profession.
Sozzani demonstrates that the moisture content of wood within the enclosure (i.e. stretcher, panel, cradling, interior frame and build-up, etc.) helps control RH (relative humidity) during temperature variations, and a silica gel component can be a hindrance. The method described uses gaskets fitted between the glazing and rebate, and between the back of frame or build-up and an aluminum or acrylic sheet backing, plus additional seals as needed.
Phibbs describes a simple method that uses a single piece of Marvelseal covering the object’s back and sealed to the front edges of the glazing with double-coated adhesive tape. Phibbs also describes a more labor-intensive method that involves Marvelseal, bonded to the front and back edges of the glazing with hot-melt adhesive, and folded and heat-sealed over the painting’s backboard.
Factors influencing the choice of microclimate method include size, weight, shape of the packaged artwork, rebate size of the frame, the exhibition environment and duration, and individual preferences. A small data logger enclosed within the envelope can record the temperature and RH.
Build-up
A build-up is an addition on the frame back that extends the rebate’s depth to improve the housing of protruding artwork. A build-up is usually made from four pieces of straight-grained and lightweight wood (e.g. sugar pine, tulip poplar), one-half to one-and-a-half inches deep, and attached to the frame back with a minimum number of woodscrews. Joining the corners of the build-up with splines or lap joints adds useful support to the frame’s own corner joinery, and beveling and painting the outside edge reduces visibility. A build-up for an oval or round frame can be prepared from birch plywood cut to a circle with band saw and jig saw. Reasons for adding a build-up include protecting the back of protruding artwork, as a component of glazing and microclimate set-ups, and as a support for failing frame joinery. Build-ups do push the hanging object away from the wall, but they also hold hardware and can provide an insulating air space behind the object.
