Using nanoiron oxide as a colorant,we controlled the glaze firing temperature conditions in a reducing atmosphere to investigate the effect of firing temperature on the color and microstructure of iron-based Jun porcelain glaze.The effect of changes in glaze firing temperature on the color and microstructure of Jun porcelain glaze was studied through various testing and characterization methods such as spectrophotometer,X-ray powder diffractometer,STA thermal analyzer,and scanning electron microscope.The results indicate that when the firing temperature increased from 1260 ℃ to 1300 ℃,the blue area of the glaze significantly increased.Within the range from 1260 ℃ to 1300 ℃,the glaze surface exhibited distinct peaks of silica crystal diffraction,but at 1320 ℃,the silica crystal phase disappeared,and the glaze surface turned glassy.With increasing temperature,the size of phase separation droplets on the glaze surface decreases.The color difference between the center and edge of Jun porcelain may be due to the larger size of the center microstructure compared to the edge microstructure.
