用NAA研究清凉寺窑和张公巷窑青瓷胎的原料特征及来源
NAA Study on Characteristics and Sources of Raw Materials of Celadon Bodies from Qingliangsi Kiln and Zhanggongxiang Kiln

摘要: 为研究清凉寺窑汝瓷胎和张公巷窑青瓷胎的原料特征及来源， 选取37个清凉寺窑汝瓷胎样品(32个汝官瓷胎和5个汝民瓷胎)、 32个张公巷窑青瓷胎样品以及14个岩石样品， 用中子活化分析 （NAA）方法测得每个样品中的23种元素含量; 使用散布分析及主成分分析方法处理NAA数据。 结果表明: 元素Fe， Ce， Ba， Ta， Th， La， Sm和Cr可作为区分汝官瓷胎和张公巷窑青瓷胎原料产地的指纹元素； 汝官瓷胎原料产地较集中， 来源相对稳定； 清凉寺窑汝民瓷胎料产地与汝官瓷基本相同， 均为就地取材； 张公巷窑青瓷胎原料产地较为分散, 与汝官瓷不同， 但二者距离相近。
关Abstract: Thirtyseven samples of ancient Chinese Ru porcelain bodies unearthed from Qingliangsi kiln(containing 32 Ru official porcelain bodies and 5 Ru folk porcelain bodies), thirtytwo samples of ancient celadon bodies from Zhanggongxiang kiln, and fourteen samples of modern mineral, were selected and analyzed by neutron activation analysis (NAA) method. Twentythree elements were measured.The data of these elemental contents were processed by scatter analysis and principle component analysis methods in order to determine the characteristics and sources of the raw materials of the celadon porcelain bodies from the foregoing two kilns. The results show that Fe, Ce, Ba, Ta, Th, La, Sm and Cr are the fingerprint elements to distinguish the ancient Ru official porcelain bodies from ancient celadon bodies of Zhanggongxiang kiln. The sources of the raw material of the ancient Ru official porcelain bodies from Qingliangsi kiln are more concentrated and stable than those from Zhanggongxiang kiln. The Ru folk porcelain bidies and the Ru official porcelain bidies from Qingliangsi kiln have the same provenance, both sources of which are local. The raw material origins of the ancient celadon bodies from Zhanggongxiang kiln is a little dispersed and the compositions of the raw material are different from the Ru porcelains, but the distance is not far away from each other.
