Problems solved by technology

At present, chromium oxide is usually used as the glaze of Ru porcelain in the preparation method of moon white glaze, but the melting point of chromium oxide is 2266°C-2435°C, the boiling point is 4000°C, and the sintering temperature of ceramics is generally difficult to reach 2266°C-2435°C , so the toxicity in chromium oxide cannot be ruled out. As a practical device, it is very harmful to the human body and needs to be further improved.

Abstract

The invention discloses a method for preparing moon white glaze craft porcelain from porcelain clay. The moon white glaze craft porcelain comprises a green body and moon white glaze, the moon white glaze comprises the following raw materials: quartzite, dolomite, white corundum, clam meal, porcelain clay, chlorite, aluminum oxide, zinc oxide, zirconium silicate and low-temperature frit; the clam meal, zirconium silicate, chlorite, white corundum and zinc oxide are added into a glaze and matched with other chemical raw materials and natural raw materials, so that the fired craft porcelain is white and transparent in glaze surface, uniform, clean and thick in glaze layer and smooth in glaze surface, and a unique moon white glaze effect is achieved.

Description

technical field [0001] The invention belongs to the field of craft porcelain preparation, and in particular relates to a method for preparing moon white glaze craft porcelain by using china clay. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Different dynasties and dynasties in Chinese history have different artistic styles and different technical characteristics. [0003] The surface glaze is a decorative layer on the surface of ceramics, and is the main factor determining the formation of ceramic glaze color. It uses natural mineral raw materials or adds some chemical raw materials in a certain proportion, melts under the action of high-temperature reducing atmosphere and covers the su...
