Abstract

The invention provides green glaze and a glazing process. The green glaze comprises following raw materials in parts by weight: 10 to 14 parts of quartz; 20-30 parts of melilite, 5-9 parts of modifiedtalcum, 6-8 parts of modified zinc oxide, 16-20 parts of kaolin, 5-7 parts of animal bone ash, 4-6 parts of plant ash, 11-15 parts of magnesian clay, 6-9 parts of copper ores, 12-14 parts of calcite,2-5 parts of glass powder, 1-3 parts of chromium oxide and 4-7 parts of iron ores. The prepared glazed porcelain is high in glossiness, smooth in surface and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of green glaze and glazed porcelain, in particular to a green glaze and a glaze application process. Background technique [0002] The development of ceramics has a close and long-standing relationship with the progress of human beings. It is a symbol of the era of human civilization. Ceramics are widely used in various fields because of their smoothness and compactness. After the baptism of the Yuan, Ming and Qing Dynasties, ceramic glazes have formed a unique form of artistic expression. [0003] Verdigris glaze is red in reducing atmosphere and green in oxidizing atmosphere. The traditional green glazes in my country all use copper as the colorant, which belongs to verdigris glaze. In the Han Dynasty of our country, copper was used as a colorant to burn copper green glazes, and green glazes on porcelain in the Song Dynasty were more common. But before the Ming Dynasty, all verdigris glazes were dark bl...
