Multi-analytical techniques, including Raman spectroscopy, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDX), optical microscopy, and Fourier-transform infrared spectroscopy (FTIR), were utilized to characterize the pigments and varnish. The analysis identified natural ultramarine blue, red lead, copper-based green (likely malachite), lead chromate, and white lead, either individually or in mixtures, within the painter's palette. Shellac was also used as a protective varnish for the painting. Moreover, SEM-EDX analysis revealed the presence of gold leaf applied beneath the paint layers. The findings suggest that the pigments used in these artworks date no earlier than the 19th century, reflecting the technical sophistication and artistic practices characteristic of the Qajar period. https://pccc.icrc.ac.ir/article_82150_40b6b176ce40dc77896070d01507b6bc.pdf
