Problems solved by technology

The cracked glaze product obtained by method 1 uses ink, which penetrates into the green body from the glaze crack, showing a crack effect, and there are certain hidden dangers in food safety, so it is generally only used in decorative art porcelain such as vases.
However, the cracked glaze product obtained by method 2 must be fired for the second time, and the rate of porcelain frying (generally 10-20%) is higher during the second firing, resulting in higher production costs.
The crackle effect of the crackle glaze product obtained by the above two methods is relatively large and rough. After a period of time, the cracking situation in the later stage of secondary cracking is more serious, which has a potential hidden danger to the quality of the product and food safety in the later stage.

Abstract

The invention discloses intermediate temperature crackled glaze porcelain for daily use. The intermediate temperature crackled glaze porcelain for daily use comprises a blank and glaze, wherein the blank is prepared from the following components in parts by weight: 10-15 parts of washed quartz powder, 28-33 parts of feldspar, 50-55 parts of washed kaolin, 5-10 parts of petuntse, and 0.5-1 part ofdolomite mineralizer. The adopted blank can realize one-step fast firing, the firing period can be shortened to 5-8 h, the ball-milling time is shortened to 12 h, and on the basis of ensuring the strength of the green body, the preparation time of the intermediate temperature crackled glaze porcelain for daily use can be shortened, the quality of a final product is improved, the quality standard of the porcelain for daily use can be met, and the water absorption ratio of the prepared intermediate temperature crackled glaze porcelain for daily use is below 0.5%.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a medium-temperature cracked-glazed daily-use porcelain and a preparation method thereof. Background technique [0002] Crackle glaze is also called grain glaze and broken grain glaze. The formation of cracks on the glaze is a defect of ceramic products, but the cracked glaze is artificially causing clear cracks in the glaze, so that the ceramic products have a unique artistic effect. Due to the different shapes of cracks, their names also vary accordingly, such as caviar grain, rubbish crack, ice crack, crab claw grain and other varieties. The most precious one is called "gold wire iron thread" or "eel claw pattern", which is interwoven with fine red and yellow cracks in the rough black grain, and the dark and shallow cracks set off each other. Crackle glazes are currently used in daily-use ceramics, but there are many defects such as product color absor...
