The microstructure and compositions of the spots on the blue colours of Jingdezhen Blue andWhite porcelain were investigated. The spots on the blue colours of Blue and White porcelainare the result of crystallization and enrichment of manganese and iron contained in cobalt bluepigment after high temperature sintering, and the compositions of the spots mainly depend on thecontents of manganese and iron in cobalt blue pigment.
