Abstract

The invention relates to a reduced metal transmutation glaze, a ceramic product prepared from the same and a preparation method and belongs to the technical field of ceramic. The reduced metal transmutation glaze comprises components in parts by mass as follows: 30-40 parts of nepheline-syenite, 4-7 parts of kyanite, 8-12 parts of barium carbonate, 22-27 parts of a frit, 14-17 parts of quartz, 7-12 parts of kaolin, 2-7 parts of calcium carbonate, 2-4 parts of cerium oxide, 28-32 parts of manganese oxide, 3-4 parts of copper oxide and 1-2 parts of nickel oxide, wherein the frit comprises components in parts by mass as follows: 48-52 parts of borax, 23-27 parts of quartz, 3-7 parts of kaolin, 13-17 parts of calcium carbonate and 3-7 parts of potassium carbonate. The reduced metal transmutation glaze ceramic product has reddish brown ground coat on the surface, gold spots flush with the glaze surface are formed on the glaze coat, and the color of the glaze is pure, bright and dazzling.

Description

Technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a reduced metal kiln glaze, ceramic products prepared by using the same, and a preparation method. Background technique [0002] With the continuous development of ceramic glazes, more and more ceramic glazes are well-known to the public. At present, the existing glazes are gradually developing in the direction of environmentally friendly lead-free, frit glazes, and the firing of glazes There are mainly oxidation firing and reduction firing, and the use of different firing methods also has a great influence on the firing effect of the glaze. Metallic glaze is a special glaze with metallic texture. The metallic color of metallic glaze is due to the addition of metal elements, such as iron oxide and copper oxide, to the glaze. At present, most of the existing metal glazes are metal glazes with a smooth surface, and have good wear resistance and corrosion resistance, and th...
