Process Principle
It employs the traditional underglaze color technique: first, various patterns are hand-painted onto the surface of a dried, formed white porcelain body using cobalt oxide pigment; then, the entire piece is coated with a colorless, transparent glaze and fired in a kiln at a high temperature of 1280–1320℃ under a reducing atmosphere in a single firing. During this process, the cobalt pigment undergoes physical and chemical reactions with the glaze layer and the porcelain body, resulting in stable coloring and patterns that never fade or flake off.
