Jingdezhen kiln and Dehua kiln are the most representative kilns among the southern white porcelain kilns. the present paper used EDXRF to test 30 pieces of Song, Yuan and Ming period' Dehua white porcelains and Jingdezhen Yuan dynasty Shufu white porcelains samples to analyze the different characteristics of the bodies and the glaze of these samples in terms of time and space. The results show that in the bodies and the glaze of Jingdezhen Shufu white porcelains the iron content is obviously on the high side, and the Dehua white porcelains' potassium content is obviously on the high side, and along with time development they have been in a rising trend, which should be the main reason for the sudden rise of Dehua white porcelain sculptures.
