Analysis on the source of raw material of the celadon bodies from Zhanggongxiang kiln and Qingliangsi kiln by PIXE

摘要

The proton induced X-ray emission (PIXE) is used to measure the chemical ingredients of seven main elements of each sample of celadon body from Qingliangsi kiln in Baofeng County and Zhanggongxiang kiln in Ruzhou City. The PIXE data are then analyzed by fuzzy cluster method, and the trend cluster diagram is obtained to determine their relation of classification and provenance. The result shows that the producing area of raw material of Ru porcelain bodies is concentrated in Qingliangsi kiln, while that of celadon bodies is slightly scattered in Zhanggongxiang kiln. The raw material origin of Ru porcelain bodies from Qingliangsi kiln in Baofeng County is different from that of Zhanggongxiang kiln in Ruzhou City. The materials of Ru Guan porcelain bodies and Ru Civil porcelain bodies in Qingliangsi kiln are basically the same.
