One of the buildings that need to be studied in this field as a prominent and valuable building is the green dome of Kerman (Qobeh Sabz) that has not been technically studied on its mosaic tiles. The colors of the tiles of this building are black, azure, white, and turquoise, yellow and green. This research has been carried out in the field of applied research to better understand the architecture of the past and the techniques of making architectural decorations. In order to achieve the goal, the method of scanning electron microscopy equipped with X-ray energy separation analysis has been used to identify glaze elements and body petrography in the studied samples. The results show that the black color of the glaze is due to the presence of substances such as manganese in the glaze. The turquoise glaze color is obtained by combining copper compounds in the rich glaze in alkaline elements such as potassium. Also, lead antimony, iron oxide and cadmium cause yellow glaze and tin in white glaze causes white color. The azure color is also caused by cobalt oxide, and the green color of the glaze is due to the presence of copper and iron. Petrographic analysis, XRD and XRF analysis for qualitative identification of minerals, existing phases, and elemental analysis of 4 samples of the tile body, shows that quartz has been used as a filler and there are calcareous soils in the bodies. Petrographic and XRD results on tile biscuits indicate oxidation baking environment and baking temperature less than 800 degrees for three samples BL, B-2, and B-4 and temperature above 850 for sample G-4.
