Description

technical field

[0001] The invention relates to a low-temperature bright red glaze for ceramics and a manufacturing method thereof. Background technique

[0002] In the field of ceramics, bright red glaze decoration is favored by consumers for its noble, rich and bright colors, but this kind of glaze has poor thermal stability and is not acid-resistant. When it is used for daily utensils, its lead and cadmium will dissolve Limit values ​​cannot meet international health standards. Moreover, the thermal stability and acid corrosion resistance of the bright red glaze are poor, and the limit values ​​of lead and cadmium dissolution are high. Contents of the invention

[0003] The purpose of the present invention is to prepare a kind of pottery and ceramics decoration for daily use, which has bright and plump color, good thermal stability and acid resistance when fired rapidly at 760 Β° C to 800 Β° C, so that the dissolution limit of lead and cadmium can be obtained. A low-tem...
