Embodiment 1

[0019] A suet matt white glaze for pottery decorations, the technological formula is calculated by mass percentage, and consists of the following components: 15% feldspar powder, 17% calcium carbonate, 5% dolomite, 12% talc, carbonic acid 8% barium, 15% zirconium silicate, 15% zirconium white frit, 5% zinc oxide, 5% aluminum oxide, 3% kaolin.

[0020] The preparation method is as follows: weigh each component according to the formula, mix them fully and put them into a grinding tank, add 45-50% water equivalent to the weight of dry powder and grind for 10 hours, then sieve the ground glaze slurry to remove iron, and the concentration Adjust to the true specific gravity of 50-54 degrees, spray or soak or other decorative methods on the pottery, dry it and then enter the kiln for 8 hours of oxidation and firing at a temperature of 1200°C-1235°C, after natural cooling After leaving the cellar, suet matte white glaze is obtained.

Abstract

The invention discloses mutton fat matt white glaze for a ceramic decoration and a preparation method of the white glaze. The white glaze is prepared from, by mass percentage, 15-25% of feldspar powder, 10-17% of calcium carbonate, 5-7% of dolomite, 6-12% of talc, 3-8% of barium carbonate, 15-20% of zirconium silicate, 10-15% of zirconium white frit, 0-6% of zinc oxide, 5-7% of aluminum oxide and 0-12% of kaolin. The components are weighed according to the formula, fully mixed and added into a grinding tank, water with the weight 45-50% that of dry powder is added for grinding for 10-15 h, then glaze slurry obtained after ball milling is subjected to iron removal and screening, and the concentration is adjusted till the true specific gravity is 50-54 degrees. A ceramic product is coated with the white glaze in a spraying mode or a soaking mode or other decoration modes. After drying, the ceramic product enters a kiln to be oxidized and fired for 8-11 h at the temperature of 1200-1235 DEG C, and the ceramic product is taken out of the kiln after being naturally cooled. The prepared mutton fat matt white glaze has the advantages of being high in processing property, high in operability and not prone to cracking.

Description

technical field [0001] The invention relates to a suet matte white glaze for pottery decorations and a preparation method thereof. Background technique [0002] The existing white glazes are mainly white glossy bright glazes, which are mainly used in dolomite white porcelain and a large number of architectural ceramics. It is characterized by the fact that it is mainly made of frit glaze with a lower firing temperature, and the cost is relatively high. For white porcelain, high-temperature sintered enamel coexists, and for architectural ceramics, bottom glaze and bright white glaze are generally applied. Products in the field of ceramics have always been affected by factors such as high water absorption rate of the green body, large moisture absorption expansion, and expansion coefficient of the green body glaze, and many problems such as cracking of single-application white glaze ceramic products have become a shortcoming in this field. Contents of the invention [0003]...
