Abstract: Energy dispersive X-ray fluorescence (EDXRF), dilatometer and microscopy were used to characterize original firing temperature, bibulous rate and chemical composition of the blue and white porcelain in the Longmen Kilns from the late Qing Dynasty to the Republic of China. Meanwhile, the experimental data were summarized and analyzed. It was shown that the blue and white porcelain in the Longmen Kilns had the characteristic composition of typical southern fetal glaze. The glaze is a calcium glaze, while the original firing temperature is about 1300 ℃. The high content of Fe was responsible for the gray color of the blue and white porcelain fetus and the dark color of the blue and white hair. The data collected in this study could be used as a reference for further exploration of blue and white porcelain in Guangxi, as well as for trade and technical exchange.
Key words: Longmen Kiln; blue and white porcelain; chemical composition; the original firing temperature
