Laboratory Studies on Materials and Pigments Used in Inscriptions and Mural Paintings in the Tomb of Ghadmagah in Neishabour

In this study, the colors used in the Inscription and mural paintings of tomb of Ghadmagah in Neishabour were analyzed by instrumental analytical methods. Ghadmagah is located in the center of the Zabarkhan section, on the Neyshabur-Mashhad Road. Ghadmagah tomb-garden is located in the village of the same name 24 kilometers east of Neyshabur, Iran, and was built in the early seventeenth century. According to historical sources Ghadmagah was built in the early eleventh century AH (ca. 1600 AD), and the origin of this site dates back to Islam. Some believe that the Ghadmagah monument was designed by Sheikh Baha’i. The architectural decoration of this building is most importantly tiling, plastering and mural paintings. Given that the building was built in different periods and originally dates back to the Safavid period. The present study aimed to study the color bedding and pigments in the Inscription and mural paintings of the building to find out what period the mural paintings in the building belong to. Mural painting is one of the Iran arts that based on the signs of old paint can be pursued to pre-history. One of the most important issues in the study of historical paintings, especially mural paint, is the identification of the nature of paintings used to decorate the walls. Identification of pigments is also important not only from the perspective of archeology but also in terms of the history of art and knowledge of degradation processes and the development of monument conservation strategies is also important. In this study, instrumental methods such as scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier- transform infrared spectroscopy (FTIR), polarized light microscopy (PLM), X-ray diffraction (XRD) and micro-Raman spectroscopy have been used for elemental and compound microanalysis of the samples.
