荥阳官庄遗址制陶作坊出土陶泥陶坯的科学分析

河南省荥阳官庄遗址发现了用于制陶的粘土原料以及未烧制的陶坯,这为研究西周中期以后中原制陶技术提供了不可多得的研究资料。为此,本研究利用能量色散X射线荧光光谱仪、X射线衍射分析仪分析了部分原料和陶坯,并使用马弗炉对其中的陶泥进行了烧制实验。结果发现,官庄遗址的制陶原料含铁量较高,烧制过程中析出磁铁矿等铁类矿物,且烧成陶色偏深;此外,制陶原料和同期陶片之间物相的趋同性和化学成分的聚类性,显示陶器本地生产的特性。研究结果为研究西周晚期至春秋早期时期制陶技术提供了基础材料。

Scientific analysis of pottery clay and billets excavated from the pottery workshop at the Guanzhuang Site in Xingyang

Clay used as the raw material for pottery, and unfired pottery billets were found at the Guanzhuang Site in Xingyang, Henan province. This excavation provides precious research materials for the study of Zhongyuan (the central plains of China) pottery-making technologies used after the middle of the Western Zhou Dynasty. In this study, we analyzed some raw materials and pottery billets using energy dispersive X-ray fluorescence (EDXRF) and X-ray diffraction (XRD) methods, and conducted re-sintering experiments on the clay in a muffle furnace. The experiments show that the iron content of the pottery raw materials from the Guanzhuang Site is high, with some iron minerals such as magnetite precipitating during firing, and that the pottery color is deep. In addition, the homogeneity of the phases and the clustering features of the chemical compositions between the raw materials and the potteries of the same period indicate the local characteristics of pottery production. This work provides basic information on pottery-making technologies from the late Western Zhou Dynasty to the early Spring and Autumn Period.
