The Jian kiln, located in present-day Jianyang county of Fujian province, mainly produced black-glazed tea bowls. Jian tea bowl was used as a utensil for tea tasting and was greatly appreciated by emperor Huizong of the Northern Song dynasty. The black glaze of Jian bowl was sometimes marked with streaks or spots, usually called hare's fur OF oil spot, which are the crystalline markings of iron oxide precipitated during firing in the dragon kiln. In this study, black-glazed Jian bowl sherds excavated from the late Northern Song strata of Luhuaping and Daluhoumen Jian kiln sites were adopted as test samples. Based on the physico-chemical foundation for the formation of glaze microstructure, the correlation among composition, microstructure, and Visual appearance has been investigated by means of energy-dispersive X-ray fluorescence, X-ray diffraction. and field emission electron microscopy. For the first time, the study provides realizing proofs for two kinds of microstructural forming mechanics. (C) 2007 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
