The composition and firing temperature of Shouzhou porcelains were analyzed using energy dispersive X-ray fluorescence (EDXRF) technology and thermodilatometry, respectively. The results indicate that: Shouzhou porcelain has the feature of high-aluminum and low-silicon in porcelain body; the porcelain glaze of Shouzhou kiln is calcareous glaze and the difference of celadon and yellow glaze probably results from variant oxidizing conditions in the kiln instead of the difference of colored elements contained in glaze; the firing temperature of celadon porcelains from Guanzuizi kiln is above 1 200 °C , and that of yellow glaze porcelains from Zhuyuanbu kiln is above 1 100 °C and about 1 200 °C.

A Liuli ring was nondestructively analyzed by EDXRF probe, to discuss the characteristic of chemical composition and the producing place of this Liuli ring. The result reveals that the chemical composition of this Liuli ring belongs to PbO-BaO-SiO2 system, which is similar to Chinese special ancient PbO-BaO-SiO2 glass dating from Chunqiu to East Han state. So, it was concluded that this Liuli ring was used Chinese special technology and formula, and was made in China. But on the appearance, this Liuli ring is not like a mature glass, but a faience or frit which is the compound of glass and crystal substance. Source

The chemical composition of some glass samples in Jin and Yuan Dynasty were analyzed by EDXRF, to discuss the technological character of these glass samples. The result shows that the chemical composition of these glass samples is very complex. According to the chemical composition, these glass samples include K2O-CaO-SiO2, Na2O-CaO-SiO2 and K2O-CaO-PbO-SiO2 glass, and a crystal SiO2 sample which was once considered a glass sample. The reason for the color of all blue glass samples is the existence of CuO, but not CoO. Source

Some Jun Porcelain samples in Jin and Yuan dynasty, that have a thin layer of substance between glaze and body, were analyzed by EDXRF (energy dispersive X-ray fluorescence) line scanning technology, to study the character of thin layer between glaze and body of Jun Porcelain. The result shows that the chemical composition of the thin layer is just between that of glaze and body. So it is concluded that this thin layer between glaze and body is a reaction layer which formed in the process of porcelain fire. Meanwhile, it is revealed that the K2O content of reaction layer is higher than those of glaze and body, and this phenomenon is different from those of other oxides. It is concluded that the phenomenon that the K2O content of reaction layer is higher than that of glaze and body, is the synthetical result of several factors, including the content of SiO2 and Al2O3 content in glaze and body, the structural character of glass, and the effect and speciality of SiO2, Al2O3 and K2O in glass, but not the result of the only factor that the penetrating capacity of K+ is strong.
