Neutron Activation Analysis of the Provenance Relation of the Ancient Yaozhou Porcelain Glaze

The contents of 29 elements in ancient Yaozhou porcelain glaze samples and the soil ore nearby museum of Yaozhou kiln are measured by neutron activation analysis(NAA), the NAA data are statistically treated by fuzzy cluster method and the trend fuzzy cluster diagram is obtained. The results indicate that the ancient Yaozhou porcelain had absolutely different glaze pigments and were made from different kilns, their sources are comparatively complex. The sources of raw materials of the black glazes in Tang dynasty are very concentrated, the green glazes and the white glazes are scattered. The sources of raw materials of the dark reddish brown glazes and the glaze of rabbit hair in Song dynasty are similar with black glazes in Tang dynasty. The sources of raw meterial of the green glazes in Song dynasty are similar with bluish white glazes in Jin dynasty. The sources of raw material of the Tang three color are scattered, and obviously not the same as other samples.
