Embodiment Construction

[0021] An embodiment of the present invention is a chrome green placer gold glaze, the raw material composition of which is: 40-50 wt% of albite, 20-30 wt% of quartz, 2-10 wt% of Longyan clay, 5-20 wt% of calcite, and 0.5-5 wt% of dolomite , strontium carbonate 1-10wt%, chromium oxide 0.5-5wt%, copper oxide 0.5-5wt%. Among them, copper oxide has a purity ≥ 98% and a fineness ≤ 0.5 μm. The raw material composition of each embodiment is as shown in table 1.

Abstract

The invention discloses chrome green gulch-gold glaze, which is prepared from the following raw materials: 40 to 50 weight percent of albite, 20 to 30 weight percent of quartz, 2 to 10 weight percent of Longyan clay, 5 to 20 weight percent of calcite, 0.5 to 5 weight percent of dolomite, 1 to 10 weight percent of strontium carbonate, 0.5 to 5 weight percent of chromic oxide and 0.5 to 5 weight percent of copper oxide. In addition, the invention further discloses application of the chrome green gulch-gold glaze. By optimizing the formula design and introducing chromium oxide into the glaze, the chrome-green gulch-gold glaze which is from light green to dark green to black green and does not contain heavy metal ions is obtained, and under the illumination condition, the chrome-green gulch-gold glaze shines like gold, is dignified and elegant and has extremely high ornamental value; and the adaptability to process conditions is high, and other glaze surfaces cannot be formed due to the change of the process conditions.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a chrome green placer gold glaze and its application. Background technique [0002] In recent years, with the improvement of people's aesthetic level, the decoration requirements for ceramic products are also constantly improving. In order to meet people's requirements for ceramic decoration, various new crackle glazes, velvet glazes, orchid junhua glazes and placer gold glazes have been developed. Placer gold glaze is a kind of special glaze in which the crystals in the glaze present fine crystals of gold luster. The crystals in the glaze have different surface directions. Due to the reflection of light, they give people a brilliant and crystal-clear feeling. These crystals are similar to sand in minerals. Gold stone, hence the name placer gold glaze. At present, the commonly used placer gold glaze is to use iron oxide crystallization agent to precipitate many fine iron...
