Colored glaze

Abstract

A colored glaze is characterized by being prepared from, by weight, 50%-60% of quartz sand with the particle size ranging from 2 mm to 4 mm, 10%-15% of potassium nitrate which serves as a fluxing agent, 10%-15% of antimony trioxide which serves as a clarifying agent, 4%-10% of manganese dioxide, 2%-8% of copper oxide, 3%-9% of nickelic trioxide, 1% of organic bentonite and 2% of sodium water glass, wherein the manganese dioxide, the copper oxide and the nickelic trioxide serve as a coloring agent. In practical use, the good-quality colored glaze art craft can be prepared through the colored glaze formula.

Description

technical field [0001] The invention relates to the technical field of preparation of inorganic amorphous materials, in particular to a kind of glass. Background technique [0002] Colored glaze is a silicate product with a long history. Its quality is crystal clear, dazzling and magnificent, which fully reflects the delicacy, delicacy and subtlety of the oriental people. It is an important decorative component. The main component of colored glaze is SiO 2 . (i.e. silica), alumina, flux lead oxide and pigments etc. [0003] The glass composition has excellent characteristics of low softening point and long material properties, which is convenient for manufacturing and suitable for glass forming. The quality of glass products is reflected in good luster, less air bubbles, streaks, and stones. The softening point and material properties of colored glaze mainly depend on the types and proportions of the ingredients in the colored glaze formula, and adding clarifiers to the b...
