Nondestructive Components Analysis of Blue and White Porcelain Unearthed from Dashangqinggong Site, Longhushan, Yingtan

Blue and white porcelain unearthed from Dashangqinggong site, Longhushan, Yingtan, was analyzed by using energy dispersive X-ray fluorescence spectrometer (EDXRF), in order to achieve nondestructive analysis of chemical composition of the tire, glaze, blue and white. It is showed that, the average content Al₂O₃ in the blue and white porcelain body is 22.2%, which is significantly higher than that in the porcelain stone materials with binary recipe of kaolin and porcelain stone surrounding Jingdezhen.
