White Jun-porcelain glaze

Abstract

The invention relates to a white Jun-porcelain glaze which is prepared from the following raw materials in parts by weight: 5-10 parts of kaolin, 3-6 parts of calcite, 10-20 parts of albite, 45-55 parts of quartz, 3-7 parts of limestone, 5-10 parts of calcined talc, 3-7 parts of zinc oxide, 4-8 parts of boron oxide, 6-10 parts of zirconium silicate and 7-15 parts of frits. In general, the white Jun-porcelain glaze provided by the invention has advantages of high glaze whiteness, good glaze gloss and low costs.

Description

technical field [0001] The invention belongs to the technical field of porcelain manufacture, and in particular relates to a white Jun porcelain glaze. Background technique [0002] White glaze is the natural color glaze of porcelain. Generally, porcelain clay and glazes contain more or less iron oxide. After the utensils are fired, they will inevitably show different shades of blue. The production of ancient white porcelain is not in the glaze. Add white coloring agent, but choose porcelain clay and glaze with less iron content to process and refine, so as to reduce the iron content to the minimum, so that pure transparent glaze can be applied on the white porcelain body, and it can be fired. To make white porcelain with high whiteness, the existing ceramic glaze is mainly made of feldspar, quartz and clay raw materials. The opacifying agent of the glaze mainly undergoes processes such as tin oxide, zinc oxide, and zirconium silicate. The cost of tin as an opacifying agent...

[0002] White glaze is the natural color glaze of porcelain. Generally, porcelain clay and glazes contain more or less iron oxide. After the utensils are fired, they will inevitably show different shades of blue. The production of ancient white porcelain is not in the glaze. Add white coloring agent, but choose porcelain clay and glaze with less iron content to process and refine, so as to reduce the iron content to the minimum, so that pure transparent glaze can be applied on the white porcelain body, and it can be fired. To make white porcelain with high whiteness, the existing ceramic glaze is mainly made of feldspar, quartz and clay raw materials. The opacifying agent of the glaze mainly undergoes processes such as tin oxide, zinc oxide, and zirconium silicate. The cost of tin as an opacifying agent is too high, and the amount of use is less and less; therefore, it is necessary to provide a white Jun porcelain glaze with high glaze whiteness, good glaze gloss and low cost
