Abstract

The invention relates to a colored glaze with favorable clarification effect and high product quality, which is prepared from the following raw materials in parts by weight: 95-110 parts of quartz sand, 42-46 parts of soda ash, 10-12 parts of aluminum oxide, 45-50 parts of lead peroxide, 1-1.5 parts of cerium oxide, 3-4 parts of antimony trioxide, 0.1-0.5 part of sodium nitrate and 1-1.5 parts of pigment. The cerium oxide and antimony trioxide are combined to be used as a clarifier, and thus, the clarification effect is obviously better than that of the independently used cerium oxide or antimony trioxide; by controlling the cerium oxide:antimony trioxide ratio at 1:(2-4), the prepared colored glaze has the advantages of high gloss, few bubbles, high transparency, few stripes in the finished product, obviously improved quality and short clarification time (6-8 hours); and the colored glaze formula materials have long acting property and low softening point, and thus, are suitable for forming the colored glaze.

Description

technical field [0001] The invention relates to the technical field of preparation of inorganic amorphous materials, in particular to a kind of colored glaze with good clarification effect and excellent product quality. Background technique [0002] Glass is a kind of 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 in architecture and an important part in art decoration. A wonderful flower. The main component of glass 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 c...
