Abstract

The invention discloses a preparation process of crackle-free powder bluish-green glaze craft porcelain. The craft porcelain comprises a green body and glaze, the green body comprises the following raw materials: feldspar, Dehua kaolin, Dehua quartz, dolomite, sepiolite, diatomite, spodumene, zirconium silicate, titanium oxide and tin oxide. The glaze comprises the following raw materials: anorthite, brucite, diopside, Dehua quartz, frit, manganese oxide, ferric oxide, titanium oxide and nickel oxide. By improving the basic formula of the glaze, the fired porcelain is greenish green and elegant in glaze color and soft in glaze surface gloss, the jade-like effect is achieved, brucite in the glaze is matched with manganese oxide, ferric oxide and nickel oxide, the porcelain is fired under aspecific process, and it is guaranteed that the fired porcelain is bluish green and elegant in glaze color.

Description

technical field [0001] The invention belongs to the field of porcelain preparation, and in particular relates to a preparation process of porcelain with a celadon glaze technique without chipping powder.
