METHOD FOR MANUFACTURING BLUE AND WHITE PATTERN HAVING GOLD OUTLINE ON PORCELAIN CLAY BODY

摘要

Disclose is a method for manufacturing a blue and white pattern having a gold outline on a porcelain clay body. The method comprises the following successive steps: providing and molding a porcelain clay body; performing a first firing of the clay body at a temperature between 700 to 850°C; sketching and coloring a contour line of the blue and white pattern region on the clay body surface, and performing a second firing at a temperature between 600 to 850°C to form the blue and white pattern; insulating a metal pattern region on the clay body surface, spraying a layer of transparent glaze; removing the insulator, forming protruding dots in the metal pattern region, and performing a third firing at a temperature between 1180 to 1320°C; applying a gold liquid to the metal pattern region on the clay body surface, and performing a fourth firing at a temperature between 700 to 850°C, completing the manufacturing of the metal pattern. The method for manufacturing a blue and white pattern having a gold outline on a porcelain clay body provided by the present invention allows not only the formation of gold outlined embossed patterns having bright colors, but also the prevention of blistering, discoloration, and cracking of the blue and white pattern.
