Because provenance information of ancient Ru-ware porcelain can provide scientific authentication of Ru-ware, some Ru-ware and Jun-ware samples were analyzed by EDXRF probe to obtain the contents of some major elements and minor elements. Then compositional data were processed through factor analysis, which is one of methods in moulti statistic analysis, and the factors are presented with scree plots and classification plots. Research shows that Xinan Jun-ware, ancient Ru-ware and modern Ru-ware can be differentiated with each other; Jun-ware and Yuan-ware can be differentiated from minor elements of glaze; what’s more, Yanhedian kiln celadon can be differentiated with other samples. This result demonstrates that combination of both plots can better reflect provenance information hidden in samples, and provide references for scientific authentication of Ru-ware and other ceramic’s provenance analysis.
