Copper red reduction transmutation glaze, copper red reduction transmutation glaze ceramic product and preparation method thereof

Abstract

The invention relates to copper red reduction transmutation glaze, a copper red reduction transmutation glaze ceramic product and a preparation method thereof, which belong to the technical field of ceramics. The copper red reduction transmutation glaze comprises the following components in parts by weight: 34 to 36 parts of nepheline syenite, 19 to 23 parts of light calcium carbonate, 2 to 5 parts of barium carbonate, 2 to 4 parts of zinc oxide, 1 to 2 parts of magnesium carbonate, 9 to 11 parts of kaolin, 14 to 18 parts of waste ceramic biscuit treatment material, 8.5 to 11 parts of quartz, 2 to 4 parts of bone ash, 1 to 4 parts of lithium carbonate and 2 to 5 parts of copper oxide. The copper red reduction transmutation glaze is uniformly in glaze surface color, has double color generation effect of being green in red and black in red and has strong classical atmosphere; and moreover, when a ceramic product is sintered according to the method, the rate of finished product is relatively high, and the method is suitable for ceramics for daily use and decorative ceramics.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a copper red reduction kiln transformation glaze, a copper red reduction kiln transformation glaze ceramic product and a preparation method thereof. Background technique [0002] There are many types of glazes, which can be divided into porcelain glazes, pottery glazes and flint glazes according to the body; high-temperature glazes and low-temperature glazes according to the firing temperature; transparent glazes, opacity glazes, color glazes, glossy glazes Glaze, dull glaze, cracked glaze, crystalline glaze, etc.; according to the glaze composition, it can be divided into lime glaze, feldspar glaze, lead glaze, lead-free glaze, boron glaze, lead-boron glaze, etc. Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials and chemical raw materials in a certain proportion and ground to make glaze sl...

Problems solved by technology

At present, there are still few reports on the glaze formula and firing method of Tonghong kiln variable glaze. The ingredients selection and firing method of copper red kiln variable glaze have an important impact on the yield and glaze quality. At present, the existing copper red kiln variable glaze is still There are the following deficiencies: the Chinese patent application number 201110308087.5 discloses a copper-red kiln-changing glaze and its preparation and use method. Although it produces copper-red glaze, it is not a uniform and meticulous copper-red glaze, but only a glazed surface. with red dot only

For example, the Chinese patent with the application number 201410386152.X discloses a formula of copper red glaze and a manufacturing process of copper red glaze porcelain. The glaze is white, and the dark red glows from the white glaze
