Identifying the Structure of Pigments Used in the Context of Five Manuscripts Related to Safavid Period

Studying various aspects of the manuscripts may be important in explaining the actual values of work, and the ways of protecting these values. Therefore, in this research 10 paint samples (blue and red) from the five manuscripts related to Safavid period (16th century) were analyzed to explore their nature and structure. First, the related literature regarding the frequent types of the paints in Safavid period and their preparing recipe were thoroughly reviewed. Then, after sampling of the paints, the analytical techniques including scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) and Fourier transform infrared spectroscopy (FTIR) were used to identify red and blue pigments structure. Obtained results confirmed that all the used red and blue pigments in these five manuscripts were of mineral origin. Moreover, the results proved that all of the red pigments used in this manuscript were of vermilion, ocher and red lead (Lead oxide), while the blue pigments are of ultramarine type. Also, the strong peak of FTIR at 2340 cm-1 proved that the ultramarine pigment used is of natural type.
