Problems solved by technology

However, due to the influence of factors such as production cost and technology, the ceramic glazes used for large-scale glaze murals and display art are mostly medium and low temperature glazes. Although they have certain environmental tolerance, they are also limited by the natural environment and use time.

Abstract

The invention discloses a high-temperature art porcelain green glaze which is prepared from the following raw materials in percentage by weight: 94% of a basic glaze and 6% of a color base, wherein the basic glaze is prepared from the following raw materials in percentage by weight: 45-57% of feldspar, 31-35% of quartz, 5-10% of white china clay, 3-5% of calcined talc, 1-2% of dolomite, 1-2% of magnesian clay and 1-2% of calcite; and the color base is prepared from the following raw materials in percentage by weight: 65-75% of chromic oxide, 10-15% of cobaltous oxide and 10-25% of zinc oxide.The porcelain glaze disclosed by the invention is sintered at a high temperature of 1300 DEG C, the sintered porcelain glaze is stable in quality, capable of enduring any natural environment and can be preserved permanently.

Description

technical field [0001] The invention belongs to the technical field of high-temperature art porcelain glazes, and in particular relates to a high-temperature art porcelain green glaze, a preparation method and a firing process thereof. Background technique [0002] High-temperature art porcelain means that in the field of art porcelain production, the melting temperature of the glaze is around 1300°C, and the kiln atmosphere is oxidized or reduced, and a unique glaze color appears after firing. [0003] Ceramic decorative materials are the main material for indoor and outdoor decoration. Although the relatively rich ceramic decorative materials in the market have characteristics that other decorative materials such as wear resistance, corrosion resistance, and weathering resistance cannot replace. However, due to the influence of factors such as production cost and technology, the ceramic glazes used for large-scale glaze murals and display art are mostly medium and low tem...
