Test and preliminary analysis of porcelains from Shouzhou kiln

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 ℃, and that of yellow glaze porcelains from Zhuyuanbu kiln is above 1 100 ℃ and about 1 200 ℃.
