Formula of matt glaze

Abstract

The invention discloses a formula of matt glaze. According to the formula, the matt glaze comprises the following components in part by weight: 20 to 30 parts of potash feldspar, 3 to 8 parts of kaolin, 3 to 8 parts of raw talc, 15 to 25 parts of dolomite, 1 to 5 parts of calcite, 30 to 50 parts of quartz, 5 to 10 parts of barium carbonate, and 3 to 8 parts of boric acid. The matt glaze is simple in formula and reasonable in proportioning; and the matt glaze which is prepared according to the formula is fine and smooth in glaze surface, good in handfeel, and high in whiteness; and production is easy to control.

Description

technical field [0001] The invention relates to a formula of glaze for ceramics, in particular to a formula of matte glaze. Background technique [0002] Matte glaze is a special glaze between glossy glaze and matte glaze. The matte glaze is different from the transparent glossy glaze, which is a group of tiny crystals embedded in the glass matrix. After the glaze is completely melted, a part of its composition is separated into crystals during the cooling process. The end products are extremely tiny and regularly dispersed. The high-grade matte glaze is pure and elegant, smooth and mercerized, like suet to the touch, like satin or silk, white like velvet, and resistant to dirt. Under the same conditions, its thermal stability and compressive strength are better than ordinary glazed surfaces. After a large area of ​​paving, the color difference is small and the overall effect is good. Under the illumination of the light, it emits flickering light and lives in it. Like a ...

AI Technical Summary

Problems solved by technology

Alkaline matte glaze is easy to adjust, but the color is not white enough to achieve velvety whiteness, and the texture of the glaze is not good, and it is easy to reveal the color of the body, which is not high-end.

However, the glaze surface of high-alumina matte glaze products is not fine enough, and the hand feeling like sheep fat cannot be achieved, and the production is not easy to control. The firing temperature is low, and it is easy to fire matte glaze or glossy glaze.
