Abstract:In this paper, the ancient porcelains excavated from Luohe city site in Song and Jin stratum were characterized comprehensively. The microscopic optical structures of the porcelain body reveal that they are typical south quartz and sericite porcelains. The energy dispersive X-ray fluorescence (EDXRF) spectra show that they contain high silicon and low aluminum chemical component. They were produced via unitary formulation process, and china stone might be the single raw material. Combined with the appearance of enamel and the whiteness, we concluded that they were typical Qingbai porcelains produced in the south of ancient China. As the regional feature could be disclosed by the composition of porcelain body, we compared the porcelain body and glaze of these samples with other Qingbai porcelain samples produced in the south kilns nearby at the same time via the PCA method, which provided sufficient supporting information to reveal the Qingbai porcelains’ technique level and trace the origin of these excavated porcelains. The scatter diagrams demonstrated that there were great similarities between the excavated porcelains and those produced in Hutian Kiln of Jingdezhen and Fanchang Kiln of Anhui. Further analyses based on the scatter diagrams of all chemical component implied that these excavated Qingbai porcelains were most possibly fired in Hutian Kiln, which were produced for the upper-middle class in Kaifeng. They were transported to central China by means of the ancient trade circulation. Combined with the ancient documents, the possible routine of ancient trade circulation was estimated. Our studies are of great importance to ascertain the ancient technique level of Qingbai porcelains and the routine of ancient trade circulation, as well as to establish the historical and cultural status of Luohe cite the site.
