Green red brown-extracting glaze and ceramic material

Abstract

The invention discloses a green red brown-extracting glaze and a ceramic material. The green red brown-extracting glaze comprises the following raw materials in parts by weight: 50-70 parts of petalite, 10-15 parts of quartz, 5-8 parts of Guizhou kaolin, 4-6 parts of Jiang letu, 8-10 parts of barium carbonate, 2-3 parts of alumina, 1-2 parts of ferric oxide, 1-2 parts of chromium sesquioxide, 0.5-1 part of cobalt oxide, and 0.5-1 part of zinc oxide. The color of the glaze changes with the change of the outside brightness, and the different glazes are generated under different environment. The green red brown-extracting glaze solves the problem of dependency of a coloring pigment or metal oxide on the basic glaze, and reduces the production difficulty of the ceramic color glaze product. The product thermal stability can achieve that no crack is generated while quenching at the temperature of 550-20 DEG C, and the green red brown-extracting glaze exceeds the requirement of GB/T2580-2002.

AI Technical Summary

Benefits of technology

This patented technology allows for changing colors when there are strong lights like from direct sunshine. It also prevents darker shades during winter months due to solar heat while still appearing green-yellow over an indoor environment where temperatures may fall below 40°F (-25°C). Additionally, this technology helps prevent damage caused by harmful chemical substances that come into contact with these colored materials.

Problems solved by technology

This patented describes various methods for producing colored ceramia compositions that exhibit varying degrees of transmittance depending upon their melting point (TFT) values. These techniques involve adding specific substances like rare earth elements to achieve desired opal effects. However, these processes result in impurities called volatilized ammonia gases, making them difficult to control. Additionally, they may lead to contaminants being released over time through evaporating gas flows.
