samples of glazes and bodies of the ancient Chinese Ru porcelain

Jun porcelain and imitative ancient ceramics were analyzed by neutron activation analysis (NAA). The contents of 36 elements in each sample were measured. The NAA data were statistically treated by fuzzy cluster method and the trend cluster diagram was obtained. Their classes and raw material sources were determined. The results show that although these samples spaned hundreds of years

came from different kilns and had different glazes colors

the bodies of the ancient Chinese Ru porcelain and Jun porcelain belong to the same kind

the glazes of the ancient Chinese Ru porcelain is similar to the glazes of the ancient Chinese Jun porcelain. The originating places of the body raw material were concentrated

and that of the glaze raw materials were scattered

the source of the glaze raw material covered that of the body raw material. The ancient Chinese Ru porcelain and Jun porcelain have basically the same raw material sources and the sources of raw material are stable in long time. It is found that most modern Jun porcelain samples are similar to the ancient Chinese Jun porcelain. Two modern Ru porcelain samples are similar to the ancient Chinese Ru porcelain

but another one drifts apart from the ancient Chinese Ru porcelain. Jingdezhen porcelain has no relation to Ru porcelain and Jun porcelain.
