What in this project has been studied, is a paper inscription to nastaliq calligraphy was written By Mahmood Ebn Abelqasem Khansari. This inscription dated 1322 AH and it has a cloth support. The paper inscription, has 21.73cm width and 648.5cm length and is maintained in Isfahan Decorative Arts Museum. In this Article the yellow color that has been employed in back ground of in this inscription was examined. Wet chemical and instrumental methods were used to identify the yellow color. It was showed concluded that the origin of yellow color is a natural dye that it is called Esparak(Weld). This plant as cause of the yellow color of the back ground studied paper Inscription.Key words:Mahmood Ebn Abelqasem Khansari, Paper Inscription, Esparak(weld), Isfahan Decorative Arts MuseumIntroductionIn this project, yellow color that used in back ground of this paper inscription was tasted. For identification of this color, chemical methods was employedy for this porpose effect of K4[Fe(CN)6] [5], KSCN[5], KI[3], AgNO3[4], KCrO4[3], H2SO4[5], NH3[3], and BaCl2[4] was studed on this color. These solvents have not any effect on yellow color and it was very stable. Then,it was decided the yellow color examine by fourier transform infrared spectroscopy(FTIR). There for, the yellow color was extracted from the back grand of the paper by using with distilled water[2] and it was mixed with KBr.Then it was tasted by FT-IR. Also same tast was done on extractine some plant that produce yellow color such as Esparak(Weld) [1]. Then spectra was taken of yellow color from paper inscription was compared with spectra were taken of the plant. Experimental

Spectra 1. Spectra was taken from Esparak(weld) (Reference:Authors)

Spectra 2. Spectra was taken from yellow color of paperin scription(Reference: Authors)

Spectra 3. Mix of Spectras were taken from yellow color of paper scription and Spectra of Esparak plant(Reference: Authors)In uo table:

The above Spectrayellow color of back ground of scription

The below Spectrayellow color of Esparak(Weld)

ConclusionsChemical solvents has not any effect on yellow color, it means that there was no metal ingredients in this color. There for the origin of yellow color was not mineral. Then the spectra was taken from the yellow color; with comparision of the spectra that was taken from the plant of Esparak(Weld) and the spectra was taken of the yellow color of back ground of this inscrioption showed that yellow color of back ground of this inscription, has been taken from the Esparak. Finaly,this study showed that the color of back ground of the paper inscription, was created by plant of Esparak(weld).AcknowledgementsThe authors would like to thank teachers and students of Art University of Isfahan for their kind help in the experiments, and thahanks of Dr Shirin Adib Khansari for her informations.References[1]: Amiri, Davoud.2007.
