Porcelain glaze and preparation and use method thereof

Abstract

The invention belongs to the field of porcelain and in particular relates to a porcelain glaze and preparation and use methods thereof. The porcelain glaze is composed of the following raw materials in parts by weight: kaolin, potassium feldspar, calcite, quartz, plant ash, fluorite, ox bone ash, soda lime, frit and bentonite, wherein the frit is composed of the following raw materials in parts byweight: silica, aluminum oxide, boric acid, potassium carbonate and sodium carbonate. The preparation and use methods thereof comprise the following steps: preparing the glaze, firing a liquefied gaskiln and the like. The glaze has quenching resistance, gloss of the glaze is increased, the highly wear-resistant transparent microcrystalline frit glaze is obtained, the firing method is scientificand effective compared with the traditional firing manner, the firing time is long, and the transmutation effect is excellent.

Description

technical field

[0001] The invention belongs to the field of porcelain, and in particular relates to a porcelain glaze and a method for preparing and using the same. Background technique

[0002] The formula of Shenhou traditional Jun glaze is relatively simple. The introduction of liquefied petroleum gas in the 1990s made the formula gradually diversified, but how to improve the physical properties of the glaze is still very important. Porcelain is the mainstream, but the disadvantage of liquefaction is that the temperature rises too fast. For example, it took more than 20 hours to fire a kiln with firewood and coal, but the fire can be stopped in 9 to 10 hours with liquefied petroleum gas. This results in a short firing time and a general kiln effect. How to prolong the firing time of liquefied gas kilns is a very confusing problem for porcelain people. Contents of the invention

Examples

Embodiment 1

[0021] Embodiment 1: A kind of porcelain glaze, is made up of the raw material of following parts by weight: 5 parts of kaolin, 25 parts of potassium feldspar, 5 parts of calcite, 10 parts of quartz, 5 parts of copper ore, 3 parts of plant ash, 5 parts of fluorite , 10 parts of bovine bone ash, 3 parts of soda stone, 5 parts of frit, and 1 part of bentonite; bentonite improves the quenching resistance of the glaze layer and increases the gloss of the glaze layer.

[0022] The frit is composed of the following raw materials in parts by weight: 50 parts of silicon dioxide, 3 parts of aluminum oxide, 15 parts of boric acid, 8 parts of potassium carbonate and 5 parts of sodium carbonate.

[0023] The method for preparing and using the frit includes: mixing the components of the high borosilicate frit according to the stated ratio, mixing evenly and sieving, and subjecting to high temperature (melting temperature is 1550-1580°C, holding time is 2-5 hours) to be melted until clarifi...
