Problems solved by technology

Due to the influence of weather, seasons, coal quality, and human factors, the firing time is long, the coal consumption is large, the temperature difference between positions is large, and the controllability is low, so the firing rate is low, which hinders the health of the Jun porcelain industry along the way. With the development, hot gas is now mostly used to fire Jun porcelain, which can not only maintain the inherent characteristics of traditional coal-fired Jun porcelain, but also has the characteristics of easy handling and high yield of Jun porcelain fired with liquefied petroleum gas or natural gas.
[0003] After using the traditional white porcelain glaze, the color is dull, opaque, and the production cost is high, and there are still a small number of products that become defective or waste products due to various defects in the glaze and process during the production process

Abstract

The invention relates to Jun porcelain coal-fire glaze. The glaze is prepared from, by weight, 20-26 parts of feldspar, 5-15 parts of quartz, 35-50 parts of glaze paste, 5-12 parts of talc, 2-5 parts of kaolin, 1-3 parts of barium carbonate, 1-2 parts of zinc oxide and 1-3 parts of limestone. Prepared Jun porcelain is smooth in glaze surface, white, bright and transparent, the yield is high, the glaze is impressive and high in visual impact effect, glaze color features are obvious, the glaze surface formed after firing is high in texture, the glaze color is smooth and fine, and the glaze surface is resistant to high temperature and corrosion, bright in gloss, lively and smooth in line and good in visual effect.

Description

technical field [0001] The invention relates to the field of Jun porcelain glazes, in particular to a Jun porcelain coal fired glaze. Background technique [0002] Jun porcelain is a kind of ornamental porcelain that presents artistic effects through natural kiln changes. From the Jin Dynasty to the end of Yuan Dynasty, coal became the main fuel for firing Jun porcelain. Coal kilns used to be mainly smoke-inverting kilns, the appearance of which is similar to that of a yurt, and the fire path is circuitous to increase the firing space and flow. Due to the influence of weather, seasons, coal quality, and human factors, the firing time is long, the coal consumption is large, the temperature difference between positions is large, and the controllability is low, so the firing rate is low, which hinders the health of the Jun porcelain industry along the way. Nowadays, hot gas is often used to fire Jun porcelain, which can not only maintain the inherent characteristics of traditi...
