抄録

<p>In order to classify the white porcelains of the Tang Dynasty unearthed in Xi’an, the chemical composition, micro-morphology, and glaze color of archaeological white porcelain samples were systemically analyzed and compared with standard white fragments from Gongyi kilns (Henan Province) and Xing kilns (Hebei Province) by a series of analytical techniques including ultra-depth of field microscope, X-ray fluorescence spectroscopy and visible spectrophotometer. The results showed that most of white fragments excavated in Xi’an could be attributed to three types. There were two types that could be classified as Xing kilns and Gongyi kilns in terms of microstructure, chemical composition, and glaze color. However, some of Xi’an white porcelains presented imperfect correspondence concerning the firing process, indicating that they might neither come from Gongyi kilns nor from Xing kilns. Or another possibility is that they might be prepared by different firing protocol. Besides, the information of raw materials and firing process of white porcelains of Gongyi kilns and Xing kilns was also discussed. The purpose of this work is to provide a scientific approach to classify ancient ceramics.</p>
