Copper-red transmutation glaze, copper-red transmutation glaze ceramic product prepared from same and preparation method

Abstract

The invention relates to a copper-red transmutation glaze, a copper-red transmutation glaze ceramic product prepared from the same and a preparation method and belongs to the technical field of ceramics. The copper-red transmutation glaze comprises components in parts by weight as follows: a glaze type basic material including 34-35 parts of nepheline syenite, 20-22 parts of calcium carbonate, 3-4 parts of barium carbonate, 2-3 parts of zinc oxide, 1-2 parts of magnesium carbonate, 26-27 parts of kaolin and 9.5-10.5 parts of nano silicon oxide, and a chromogenic reagent including 1.8-2.5 parts of lithium carbonate, 2-4 parts of bone ash and 2-4 parts of copper carbonate. The ceramic product prepared from the copper-red transmutation glaze through firing has brighter red color, the glaze color is uniformly distributed, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a copper red kiln variable glaze, a copper red kiln variable glaze ceramic product prepared by using the same and a preparation method. Background technique [0002] Copper red glaze has been loved by people since ancient times. It is a relatively expensive glaze. It was once lost in the middle of the Ming Dynasty, and it was replaced by alum red. Among the copper red glazes, the most vivid color is Langyao red. Generally, copper red glazes use copper-containing substances as coloring agents, and the red glazes are made by reduction firing. The quality of the glaze is affected by the materials and firing conditions. The most important thing is that as long as the materials are slightly different or deviated, the reduction will be incomplete, and even the glaze will turn black and green. Bright copper red has always been relatively rare and sought after by people. G...

Problems solved by technology

Generally, the raw material formula and process for firing copper red glaze with better texture have not been made public. The copper red glaze fired according to the existing copper red glaze not only has poor color effect, but some even have Uneven glaze color distribution, pinholes and other defects on the glaze surface. Even if additives such as stabilizers are added to the glaze for firing, the above problems are unavoidable. The main reason is that the formula of the glaze is unreasonable and the reduction Unreasonable setting of firing conditions
