Coloring Mechanism and Raman Analysis of Purple Gold Glaze under Different Process Parameters
Purple gold glaze,a kind of high-temperature color glaze with iron oxide as the coloring agent,plays a pivotal role in the history of the development of ancient Chinese ceramics.At present,there are few scientific and technological analyses of purple gold glaze,and most of them are based on archaeology and art.In this paper,the influence of process parameters on the microstructure characteristics and color mechanism of purple gold glaze was revealed by adjusting the glaze ball grinding time,glaze thickness and firing temperature.Further analysis by Raman and Scanning Electron Microscopy(SEM)showed that when the ball grinding time was 15 min,the glazing time was 1 s,and the firing temperature was 1 310 ℃,there were ε-Fe2O3 crystals with high purity in the glaze,and the gloss of the glaze was high.At the same time,because more nanoparticles are distributed near the dendritic crystals,the nanoparticles are dissolved at high temperature,which promotes the formation of multi-layer stacked secondary dendrites,and then makes the glaze present a strong metallic texture.
