A number of Mi’se porcelains have been unearthed at Shanglin Lake, Zhejiang Province. These porcelains discussed here are similar to those excavated from the underground palace of Famen Temple in terms of appearance and shape, as well as stacking and firing methods. Through field investigation into the kiln site and scientific tests, including thermoluminescence (TL) dating, energy dispersive X-ray fluorescence (EDXRF) of chemical composition analysis, microstructural analysis and apparent porosity testing of the samples, we find that this batch of Mi’se porcelains is similar to Yue Kiln porcelains, in general, in terms of chemical composition and microstructure. Therefore, it is impossible to distinguish Mi’se porcelains from average Yue Kiln porcelains in these two respects. However, with regard to technology, Mi’se porcelains boast some superior characteristics, in that the materials were processed with more attention to details, the bodies were trimmed in a more meticulous way, glaze was applied more evenly and symmetrically, and porcelain saggers were used for stacking and firing. These studies indicate that Mi’se porcelains are high-quality products of Yue Kiln and were made using advanced technologies.
