Abstract

The invention discloses a cracked glaze and a making process thereof. The cracked glaze is composed of albite, kaolin, quartz, zinc oxide, barium carbonate and frits, wherein the frits are composed of quartz, red lead, feldspar, dolomite and barium carbonate, and the feldspar is composed of potassium feldspar and albite according to the mass ratio. The making process comprises the steps of smashing quartz, red lead, potassium feldspar, albite, dolomite and barium carbonate, uniformly mixing, and smelting to prepare the frits; and respectively smashing all the raw materials and the frits, uniformly mixing according to a certain ratio, then, adding water to stir, sieving by using a mesh screen after ball milling, coating the prepared glaze on the surface of a ceramic blank, firing in a roasting kiln, and cooling after taking the glaze out of the kiln. The cracked glaze disclosed by the invention is simple in component and reasonable in formula, the glaze surface effect of the prepared cracked glaze is stable, glaze surfaces with different effects can be made through changing the contents of the components, and the crack is good in effect and more uniform and attractive; and the making process is short in firing time and low in firing temperature, so that the energy consumption is reduced, the energy is saved, the environment is protected, 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...
