Problems solved by technology

[0004] The production process of ancient copper red glaze is almost lost. In recent years, copper red glaze technology has been restored after years of efforts, and the technology of copper red glaze ceramic products has been greatly developed. However, due to the complicated production process and low yield, Therefore, the output is very low, the products of good quality are scarce, and the market price is expensive, which is far from meeting the needs of consumption.

Abstract

The invention relates to novel copper-iron colored glaze. The novel copper-iron colored glaze comprises, by weight, 20-34 parts of quartz, 5-14 parts of kaolin, 12-17 parts of calcite, 0-3 parts of bone powder, 2-8 parts of barium carbonate, 30-50 parts of albite, 2-2.5 parts of stannic oxide, 0.5-0.8 part of copper oxide, 0-2 parts of talc and 0-4 parts of glass powder. The invention further provides a method for manufacturing household porcelain through using the copper-iron colored glaze. The glaze color of the household porcelain manufactured through the method is bright, color development is even, glassiness and brightness are good, few defects exist in the glaze, and cracks will not occur.

Description

technical field [0001] The invention relates to a novel copper-iron colored glaze and a method for making daily-use porcelain with it. Background technique [0002] Copper red glaze is a red glaze fired with copper-containing substances as a colorant by reducing flames. Theoretically speaking, if copper oxide is used as a coloring agent and calcined in a reducing flame, a bright red color can be obtained, which is copper red glaze. But since ancient times, this kind of bright red firing has been extremely rare and has been treasured by the world. Calcining with a proper reducing flame can get a beautiful red color, as long as there is a slight deviation, incomplete reduction, or partial oxidation, it may cause graying, greening, blackening, or burning loss. According to archaeological data, the Tang Dynasty in my country has begun to use copper to burn red, and the Jiaocheng kiln in Shanxi Province produced white glaze and red spot wares; the Jun kiln in Yuxian County, Hen...
