Considering the importance of orpiment pigment in Persian Art, this research investigates yellow pigment derived from the orpiment mines in Tekab City, West Azerbaijan province. In this regard, spectroscopy and Microscopy methods were used to examine the pigments and colors made from them based on different treatises such as "Haliya al-Katab", "ink and Bookbinding", and also "Ink and Calligraphy". The results of Raman spectroscopy showed that Arabic gum and sesame oil did not interfere significantly with the pigment spectrum, making orpiment identification possible using this method. PLM also greatly assists in identifying orpiment based on its crystallographic features. SEM-EDX examinations also showed arsenic and sulfur content of 29.09% and 49.82% (wt%) in this pigment. Furthermore, FTIR spectroscopy results showed that the overall spectroscopic characteristics of orpiment were better preserved in combination with oil than gum. However, due to the absence of the absorption band of this pigment in the mid-infrared region, it is not a suitable method for identifying orpiment, but it can be used to identify the binder.
