Abstract: In order to find out the relationship between copper-red glaze of official Jun porcelain and the chemical elements in them, the chemical elements of six color glazes of official Jun porcelain are tested. Box plot analysis and Factor analysis are used to analyze the data to explore the relationship between the glaze color and the number of chemical elements in glaze. The results show the six porcelain glazes can be divided into three categories: 1) begonia-red and chicken-blood-red; 2) purple tinged with red, blue and violet; 3) grape purple and eggplant purple.
