Initial analysis of origin relations between glaze raw materials of past age Yaozhou Kilns

Yaozhou kiln is one of the famous ancient kilns.In order to seek for the origin relations between glaze raw materials of Yaozhou kilns of past ages,the content of 29 elements in ancient Yaozhou porcelain glaze samples are measured by neutron activation analysis(NAA),the NAA data are statistically treated by fuzzy cluster method.The results indicate that the sources of raw materials of the black glazes in Tang Dynasty are very concentrated,and the mineral compositinos are simple.The sources of raw materials of green glazes and the white glazes are scattered.The green glazes in Wu dynasty form a connecting link between the preceding and following.The batch formula of the green glazes in Song Dynasty is stable.The sources of raw materials of lunar whits glazes in Jin Dynasty are similar with the green glazes in Song dynasty.The sources of raw material of the Tang three color are scattered,and obviously not the same as other samples.
