Problems solved by technology

[0002] Crackle glaze makes the corresponding products favored by many consumers with its unique crackle effect, but the glaze effect of the existing crackle glaze is unstable, and the glaze effect is single, the variety is monotonous, and it cannot cater to the needs of consumers with different personalities; in addition, the current Most of the cracked glazes have long firing time and high firing temperature, which consume more fuel for production, relatively low production efficiency and high production cost.

Abstract

The invention discloses crackle glaze and a manufacturing process. The crackle glaze is composed of a transparent glaze material and a high-expansion glaze material according to a mass percentage. The transparent glaze material and the high-expansion glaze material are composed of silicon dioxide, aluminum oxide, potassium feldspar, albite, calcium carbonate, borax and barium carbonate of different mass percents. The raw materials are evenly mixed in proportion, the mixture and water are mixed in proportion, a crackle glaze material is obtained after ball milling and sieving, the surface of a ceramic green body is coated with the crackle glaze material and then the ceramic green body is sent into a heating-up furnace to be fired, a semi-finished product with a crackle cracked glaze effect is obtained after drawing and cooling, and cracks on the outer surface of the semi-finished product are colored. The crackle glaze is simple in composition and rational in formula, the glaze effect of the manufactured crackle glaze is stable, the crack effect is good, and the crackle glaze is more uniform and attractive. The firing time in the manufacturing process is short, the firing temperature is low, so that the energy consumption is reduced, the crackle glaze saves energy and is environmentally friendly, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of glaze preparation, in particular to a cracked glaze and a manufacturing process. Background technique [0002] Crackle glazes are favored by many consumers for their unique crackle effects. However, the glaze effect of existing crackle glazes is unstable, and the glaze effect is single, and the variety is monotonous, which cannot meet the needs of consumers with different personalities; Most of the cracked glazes have long firing time and high firing temperature, which consume more fuel for production, relatively low production efficiency and high production cost. Contents of the invention [0003] The object of the present invention is to provide a cracked glaze and its manufacturing process to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A crackle glaze, which i...
