The use of high-energy synchrotron rays in order to identify and characterize historical and cultural materials as accurately as possible, usually in a non-destructive manner and with very high accuracy, has become a suitable method to identify the investigated materials in very small quantities. Furthermore, cathodoluminescence rays can lead to better identification of the chemical composition and phase changes in the historical samples. Cathodoluminescence rays generated from the crystalline compounds lead to new mineralogical interpretations in order to better understand the manufacturing technology and the origin of historical material. In line with the archaeological investigation and studies conducted during the years 1392-1393, a significant number of Celadon pottery and engraved and glazed pottery were found in the area of Gore. In this research, 7 pieces of exposed pottery were examined using conventional laboratory methods and the also high-energy X-ray beam produced in synchrotron and microscopic cathodoluminescence. In line with these studies, it was found that these potteries were made of kaolinite clay and baked at a temperature of about 1200 degrees Celsius in two manufacturing stages, and specific proportions of raw materials Si/Al were used in the chemical composition of their body and glaze. This proportion and the way of firing and the condition of the kiln were proof of the coherence and strength of the celadon, which is identical to the temperature interval of the formation of the crystalline phases between the body and the glaze, so-called reaction phase-interphase area.
