Color glazed porcelain uses a variety of metal oxides and natural ores as colorants. When a certain oxidized metal is added to the glaze, it will show an inherent color after roasting at high or low temperature. This is color glaze. The metal oxides that play the role of colorants mainly affect the color formation of the glaze.
