Abstract

The invention relates to jun porcelain with royal blue glaze, and a preparation technology of the jun porcelain. The prepared glaze porcelain with blue bottom and red spots is high in finished productrate and low in manufacturing cost, and has very high artistic value and economic value; copper and cobalt elements are used in the raw materials according to a specific proportion and complement each other, so that the glazing color of royal blue is produced by firing; furthermore, the glazing color is stable in color generation, quiet and beautiful; compared with the same color series of peacock blue glaze, the glaze provided by the invention is more uniform and cleaner, and has jade texture sense; kaolin has very good plasticity and cohesive property, so that the risk that fracture is caused due to the increment of cracks during sintering can be reduced.
