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.

Among the architectural arrays of Imamzadeh Hossein in Qazvin that can provide valuable information to researchers, are the remaining parts of the murals. Considering that Qazvin was the capital during the second period of Safavid rule, the study of Safavid and Qajar period buildings in this city can be of great importance. Compared to the existing historical monuments, few studies have been done on the technical knowledge of the layers of historical murals.In the present study, the identification and recognition of pigments related to the remaining murals of this monument and gilded layers has been considered. Also, in order to complete the technical information of the murals, the mortar of the fine coat (finishing plaster) and scratch coat (levelling coat) under the paint has been studied in terms of structure and chemical composition. To identify the pigments used in the murals as well as the materials used in the mortar of the underlying layers of the mural and the floor mortar, the hydraulic properties and the mineral and chemical composition of the mortar from X-ray diffraction, scanning electron microscopy coupled with energy dispersive spectroscopy and digital microscope have been used. As a result of the studies, it was found that the Pastiglia in the murals is made of a mixture of gypsum and Bole (Armenian Bole, Hormoz Bole). Apply a white Primary layer on the pastiglia on which the gold leaf is applied with low copper impurity. In this murals, three types of gold sheets have been executed. Green: A mixture of arsenic pigment with azure blue and Prussian blue; Green-blue: a mixture of green earth pigment (Celadonite) with white lithopone; Blue: a mixture of azure and Prussian blue pigments with White lead; Red: A mixture of ocher red and orange arsenic; Primary layer filler: a mixture of Huntite and White lead; black: It is a mixture of cobalt black and iron black. The structure and composition of mortars were also identified.
