用中子活化分析法研究古钧瓷和古汝瓷起源关系

Originating relation studies on ancient porcelains of Chinese Ru and Jun by NAA

将 5 0个古汝瓷、古钧瓷和仿古瓷的釉和胎等样品进行中子活化分析 ,测定每个样品的 36种微量元素含量 ,将这些测量数据进行模糊聚类分析 ,得到动态聚类图 ,以确定它们的分类和材料来源。结果表明 ,这批样品虽然跨越几百年 ,釉色不同 ,出自不同的窑口 ,但古汝瓷胎和古钧瓷胎同类 ,古汝瓷釉和古钧瓷釉同类。胎料产地集中 ,釉料产地分散些 ,釉料产地覆盖了胎料产地。古汝瓷和古钧瓷有着基本相同的原料来源 ,而且这些材料来源是长期稳定的。现代钧瓷多数与古钧瓷相近 ;2个现代汝瓷和古汝瓷相似 ,1个与古汝瓷疏远 ;景德镇瓷与汝瓷、钧瓷无关。

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.
