Abstract Thirty-nine porcelain pieces were studied by composition and thin-section petrographic analysis. Combined with typological identification, they mainly belonged to: Dongzhang kiln (Fujian Province), Yue kiln (Zhejiang Province), Changsha kiln (Hunan Province), Longquan kiln (Zhejiang Province), and Jingdezhen kiln (Jiangxi Province). They manifested that the Qinglong Town, as a trade node of the maritime Silk Road during the Tang and Song Dynasties had played an important transit station for porcelain export. Different porcelain have varied petrographic characteristics due to differences in clay selection and firing process. However, this petrographic feature is different in large regional scale like south and north China. Meanwhile, in the small area scale, such as the Fujian Province, although there are different kilns, because of the use of the same red soil from Minjiang River Basin, the petrographic characteristics show consistency.
