Why does glaze make ceramic surface smooth?
The glaze is applied to the ceramic surface and is dried and melted in a high temperature furnace. It is similar to paint and forms a smooth surface under the action of surface tension.
Ancient or made, oil, rust, also known as oil, glaze, glaze, medicine, etc.. Glaze is a silicate, applied on ceramics glaze with quartz, feldspar and clay as raw material, after grinding, adding water, coating on the surface of the blank body, the temperature of the roasting and melting, when the temperature falls, the formation of thin glass ceramic surface. It enables the ceramic to increase mechanical strength, thermal stability, dielectric strength, and to prevent the erosion of liquids and gases. The glaze also increases the beauty of the porcelain and is easy to clean and not stained by dust. Many kinds of glaze, according to material composition can be divided into lime glaze, glaze, glaze, feldspar lead and boron lead-free glaze glaze, glaze, glaze of lead boron salt; according to the preparation methods can be divided into raw glaze, glaze; according to the sintering temperature can be divided into high temperature, low temperature glaze glaze; according to the appearance features can be divided into transparent glaze, glaze, color glaze, crystalline glaze, color glaze, glaze crack; body according to the species can be divided into porcelain glaze, glaze pottery, stoneware glaze etc.. There are mainly two kinds of feldspar glaze and lime glaze in China's ceramic production. Due to the oxidation of metal contained in glaze and different sintering atmosphere different, glaze with blue, black, green, yellow, red, blue and purple. The ancient white porcelain was almost colorless transparent glaze.
