Problems solved by technology

[0003] 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.

Abstract

The invention provides a high-strength crackle glazed ceramic product. The product comprises a blank and glaze. The glaze comprises kaolin, quartz, potassium feldspar, clay, cordierite and talc. The glaze comprises potassium feldspar, albite, calcite, kaolin, dolomite, quartz, barium carbonate, zinc oxide, zircon and plant ash. A preparation method of the high-strength crackle glazed ceramic product comprises: mixing blank materials, mixing glaze materials, respectively adding water into the blank materials and the glaze materials, carrying out wet grinding through a ball mill, carrying out screening to obtain blank slurry and glaze slurry, preparing a blank from the blank slurry, carrying out biscuiting, carrying out glazing and carrying out firing. The glaze layer of the ceramic productcontains patterns with different brightness and the patterns are distributed layer by layer like crystal flowers so that antique artistic beauty is created.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a high-strength cracked glaze ceramic product and a manufacturing method thereof. Background technique [0002] Crackle glaze is a decorative art of porcelain. The glazed surface of porcelain is covered with many small cracks, some are sparse and some are dense, some are thick and some are thin, some are long and some are short, some are curved and some are straight, they are shaped like cracks, crab claws or ice cracks, which are called crack glazes. Glaze cracks are originally a defect in firing, but when the glaze cracks of some products are very special, the lines are uniform and clear, and they are all over the surface, giving people a special aesthetic feeling, so people get it from it. Inspired, summed up the experience, and consciously caused the cracks on the sleeve surface, thus gradually creating the crack glaze. The reason for the cracked glaze is that ...
