Black silver drop reduced transmutation glaze, black silver drop reduced transmutation glaze ceramic product prepared using same and preparation method

Abstract

The invention relates to black silver drop reduced transmutation glaze, a black silver drop reduced transmutation glaze ceramic product prepared using the same and a preparation method and belongs to the technical field of ceramic. The black silver drop reduced transmutation glaze comprises, by mass, 33-36 parts of nepheline syenite, 18-22 parts of light calcium carbonate, 4-6 parts of barium carbonate, 2-4 parts of zinc oxide, 1-3 parts of magnesium carbonate, 9-12 pats of kaolin, 14-18 parts of waste ceramic biscuit treating material, 8-12 parts of quartz, 2-6 parts of bone ash, 2-8 parts of manganese oxide and 2-7 parts of copper oxide. The black silver drop reduced transmutation glaze is simple and easy in implementing of glazing mode, and production efficiency can be improved effectively; the black silver drop reduced transmutation glaze ceramic product prepared has pitch-black glaze surface and is modest luxury, and silver drops are adopted for decorating, so that the product is more noble and elegant; the product is calcined according to the method, finished product rate of the ceramic product can be up to higher than 92%, and the black silver drop reduced transmutation glaze is suitable for being used to produce ceramic for daily use and decorating ceramic.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a black silver-drop reduced kiln-changed glaze, a black silver-drop reduced kiln-changed glaze ceramic product and a preparation method thereof. Background technique [0002] Glaze is a thin glassy layer covering the surface of the ceramic body. Its surface is smooth and shiny, and it is impervious to water and not easy to stain. It can not only improve the physical properties of the ceramic body, but also enhance and beautify the appearance of ceramic products. Black glaze is a glaze with black luster. Generally, black glaze needs to be fired at high temperature. Because of its unique glaze color, black glaze is widely favored by the world. [0003] Kiln-changing glaze means that when porcelain is fired in a kiln, because the glaze contains a variety of color elements, after oxidation or reduction, it will show unexpected glaze color effects after it comes out of th...

[0004] The Chinese patent that application number is 200710193874.3 discloses a kind of preparation method of black-glazed gold drop glaze and product thereof, although it discloses a kind of preparation method of black-glazed gold drop glaze and product thereof fired at higher temperature, The glaze is black as the base and golden yellow as the decoration. It has wide adaptability and good thermal stability. However, the method of glazing the glaze is cumbersome, and the inner and outer glazes need to be glazed separately. The finished product rate of the product that its preparation method makes is also unsatisfactory
