Antique matte cracked glaze and preparation technology thereof

Abstract

The invention discloses antique matte cracked glaze and a preparation technology thereof. The cracked glaze comprises the following raw materials in parts by weight: 25-30 parts of feldspar, 40-45 parts of limestone, 5-10 parts of kaolin, 5-10 parts of calcined kaolin, and 9-15 parts of quartz. The preparation technology of the antique matte cracked glaze comprises the following steps that: the raw materials are uniformly mixed to obtain a mixture; water is added into the mixture with the weight ratio of the mixture to the water being equal to 1:0.80, and ball-milling and sieving are performed on the mixture and the water to obtain a glaze material of the cracked glaze; and a red clay porcelain body coated with the glaze material is sintered, and then the sintered red clay porcelain body is colored, thus obtaining the finished product of the antique matte cracked glaze. The glazed effect of the antique matte cracked glaze is stable; the glaze color of the antique matte cracked glaze is slightly dim, so that the antique matte cracked glaze is more of an antique beauty; in addition, as the sintering time for a single batch of the antique matte cracked glaze can be 12 hours, the quick sintering adaptability of the antique matte cracked glaze is high, so that the antique matte cracked glaze is applicable to volume production; and as the sintering time is short, the efficient production is realized, the aims of energy conservation and environmental friendliness are achieved, the production cost of the antique matte cracked glaze is reduced, and the market competitiveness of theantique matte cracked glaze is improved, so that the antique matte cracked glaze has very high social and economic benefits.

Description

technical field [0001] The invention relates to a glaze for ceramics and a preparation process thereof, in particular to an antique matte crack glaze and a preparation process thereof. 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 poor ability to adapt to rapid firing, consume more fuel for production, relatively low production efficiency, and high production cost. Contents of the invention [0003] The invention provides an antique matt crackle glaze and a preparation process thereof to overcome the problems of unstable glaze effect and single glaze effect, poor adaptability to rapid firing, low production efficiency and high cost existing in most existing crackle glazes.
