Low-temperature cracked glaze ceramic product and manufacturing method thereof

Abstract

The invention provides a low-temperature cracked glaze ceramic product, which comprises a body material and a glaze material, and the body material comprises the following raw materials: kaolin, quartz, potassium feldspar, cordierite, clay, talc, carbon fiber and ceramic micro powder; the glaze comprises the following raw materials: potassium feldspar, albite, kaolin, dolomite, quartz, borax, frit, ferric sulfate and plant ash, and the frit comprises the following raw materials: aluminum oxide, zinc oxide, copper oxide and heavy calcium carbonate. The manufacturing method of the low-temperature cracked glaze ceramic product comprises the following steps: respectively mixing the body material and the glaze material, adding water, performing wet milling by using a ball mill, and sieving to obtain body material slurry and glaze slurry; preparing a green body from the tire slurry, and biscuit-firing; glazing is conducted; and sintering. The ceramic product prepared by firing at low temperature is short in firing time and low in temperature, so that the energy consumption is low, the yield is high, and the production cost is reduced; meanwhile, glaze cracks are very special, lines are uniform and clear, and the glaze is fully distributed on the surface and is stacked and distributed layer by layer like crystal flowers, so that an antique artistic aesthetic feeling is created.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a low-temperature cracked glaze ceramic product and a manufacturing method thereof. Background technique [0002] Among the ceramic decorative glazes, there is also a special glaze called crack glaze. The glaze surface is covered with many small cracks, the lines are sparse and dense, thick and thin, long, short, curved and straight, like cracks, like crab claws, like brocade, like water lines, these various lines are in the porcelain. The surface forms a unique decoration. [0003] The generation of cracked glaze, like kiln-varnished glaze, is also accidental at first. Moreover, the glaze crack is originally a defect in the firing process, but when the glaze crack of some products is very special, the lines are uniform and clear, and the surface is covered, giving people a special aesthetic feeling, so people start from it. I was inspired to sum up my experience ...

AI Technical Summary

Problems solved by technology

[0004] Generally, when firing glaze, about 1100°C belongs to low-temperature firing, about 1200°C belongs to medium-temperature firing, and 1300°C belongs to high-temperature firing. The crackle glaze has made the corresponding products popular with many consumers because of its unique crackle effect, but the existing crackle glaze On the one hand, the glaze effect of ceramic products is unstable, and the glaze effect is single, and the variety is monotonous; on the other hand, the ceramics are not strong and easy to break

Thereby it is impossible to cater to the needs of consumers with different personalities; in addition, most of the existing crackle glazes have a long firing time and a high firing temperature, which consumes more fuel for production, relatively low production efficiency, and high production costs.
