Paper Title:
Microstructure Characteristics of the Black-Glazed Shreds Excavated from the Qingliangsi Kiln
  Abstract

The black-glazed shreds from Qingliangsi kiln were studied. The glaze and body micro- structures, compositions and crystal phases were observed and analyzed by field emission scanning electron, microscope multiple functions electron probe-energy spectrum instrument and field emission transmission electron microscope. The iron oxide crystal in oil spot was mainly the ε-Fe2O3 in the orientation of the zone axis [001], and also few content of ε-Fe2O3 in the orientation of the zone axis [412]. The brown oil spots on the glaze surface were aggregations of a great deal of iron oxide hematite crystals. Bodies of black-glazed shreds have high Al2O3 (26.47 % ~ 30.48%) and low SiO2 (62.77% ~ 66.20%), which pertained to the typical recipe of north porcelain bodies. The glaze are attributed to calcium-alkali glaze, and according to the ratio of Al2O3:SiO2, it belongs to the crystallization glaze.
