WHAT IS CLAY?
Clay is a naturally occurring mineral material, highly plastic when damp,
chemically inert, and refractory when fired. Alumina + Silica + Water
Al2O3 2SiO2 2H2O
PLASTICITY of clay is due to the shape and size of its particles,chemical/electrical attraction of particles,
and the presence of organic material.

CLAY BODIESCLAY BODIES
A clay body is a formulation of clays and other ingredients designed for particular properties such as color, texture, maturing temperature,
plasticity, shrinkage, and drying and firing properties.
Additions to clay bodies might include fluxes,sand, grog or combustible fillers (like sawdust) to “open” or lighten
the clay body, bentonite or ball clay for plasticity, iron oxide for color.

Evidence has been found for use of potter’s wheels in the Middle East (Turkey, Iraq, Egypt) as early as 4000-7000 BCE.
The potter’s wheel probably evolved from use of a supporting bowl which is rotated, in the construction of coil pots (as, at left, in Mexico.)

1. Centering: coning up
Centering: compressing the mass
