Problems solved by technology

At present, the glaze used in ceramic products improves the brightness by adding lead, but the lead will be dissolved when used, which is harmful to human health, and the composition of the glaze is not fine and smooth enough, so that pinholes and bubbles appear in the glaze layer, and the gloss of the glaze layer Lower, obviously reduces the grade of ceramic products, how to improve the brightness of the glaze is a technical problem that needs to be solved urgently in this field

Abstract

The invention discloses glaze capable of increasing brightness and a preparation process of the glaze, and relates to the technical field of porcelain craft glaze. The glaze is prepared from, by weight, 5-10 parts of modified feldspar powder, 4-8 parts of barite powder, 10-20 parts of modified mica powder, 10-20 parts of modified quartz sand, 1-3 parts of barium oxide, 2-4 parts of zinc oxide, 0.6-1 part of sodium hexametaphosphate, 2-4 parts of zirconium silicate, 2-4 parts of manganese carbonate, 1-3 parts of modified asbestos wool, 5-10 parts of titanium dioxide, 1-3 parts of celestite, 2-6parts of lithia, 1-3 parts ofbastnasite, 1-3 parts oftantalum pentoxide, 1-3 parts of bprpm trioxide, 0.5-1 part ofhafnium oxide, 1-3 parts of modified nano calcium carbonate and 1-3 parts of modified glass fiber. The glaze has the beneficial effect that the brightness of the glaze can be improved.

Description

technical field [0001] The invention relates to the technical field of porcelain craft glaze, in particular to a glaze that can increase brightness and a preparation process thereof. Background technique [0002] In China's splendid artistic culture for thousands of years, ceramic art has always occupied a relatively important position. As for ceramic art, the glaze is a key part. Porcelain is a product formed and fired from a mixture of clay, feldspar, quartz, etc. In order to give the porcelain a beautiful appearance, a layer of ceramic glaze is usually applied to the porcelain. For ceramic products, the ceramic glaze can improve the performance and play a decorative role. [0003] Generally speaking, glaze is a colorless or colored glassy thin layer or a mixed layer of vitreous body and crystal covering the surface of porcelain products. viscous material. Glaze attached to the surface of porcelain products can not only play a decorative role, but also improve the perf...
