a) Surface of the HF Jian sherd analyzed in this paper. Brown/yellow stripes over a black glaze are clearly observed; b) OS sample from this study. The spots with a silver color are spread over the black glaze; c) Cross section of the HF sample observed with an optical microscope. Crystals and bubbles are dispersed in the thick semi-opaque glaze. d). Schematic drawing of Jian bowl surface pattern formation process. The surface patterns of the Jian wares such as Hare's Fur (HF) and Oil Spot (OS) are believed to be linked to the crystallization of iron oxides.
