用中子活化分析研究郊坛下官窑与清凉寺汝窑的原料来源

A study on provenance relation between Jiaotanxia ancient Guan porcelain and Qinliangsi ancient Ru porcelain by NAA

选取11个清凉寺窑古汝瓷、23个郊坛下窑古官瓷、4个现代仿古官瓷的釉和胎等样品进行中子活化分析(NAA),测定每个样品的微量元素含量,将这些测量数据进行模糊聚类分析,分别得到胎和釉的动态模糊聚类分析图,以确定它们的原料来源。结果表明,郊坛下古官瓷胎的原料来源非常集中,清凉寺古汝瓷胎的原料来源稍分散些;古官瓷釉的原料来源比较集中,古汝瓷釉的原料来源分散,古汝瓷釉和古官瓷釉的原料来源明显不同。郊坛下窑官瓷的胎和釉与清凉寺窑汝瓷的胎和釉既有差异又有可比性。

11 samples of ancient Chinese Ru porcelain from Qingliangsi kiln, 23 samples of ancient Chinese Guan porcelain from Jiaotanxia kiln and 4 samples of modern archaized Guan porcelain were obtained to determine the contents of elements in each of them by neutron activation analysis (NAA). The NAA data were further analyzed using fuzzy cluster analysis to obtain the fuzzy cluster trend diagrams for the bodies samples and the glazes samples respectively. The analysis shows that the raw material origins of the Jiaotanxia ancient Chinese Guan porcelain bodies samples are very concentrated; those of the Qingliangsi ancient Chinese Ru porcelain bodies samples are a little dispersed; those of ancient Chinese Guan porcelain glazes samples are relatively concentrated; those of ancient Chinese Ru porcelain glazes samples are dispersed; and the origins of the raw material of ancient Chinese Guan porcelain glazes samples are obviously different from those of ancient Chinese Ru porcelain glazes samples. The bodies samples and glazes samples of Jiaotanxia ancient Chinese Guan porcelain and those of Qingliangsi ancient Chinese Ru porcelain have some difference but can be compared with each other.
