Abstract

The invention provides copper-red glaze. The copper-red glaze is prepared from the following raw materials in parts by weight: 37 to 43 parts of melilite, 12 to 18 parts of quartz, 9 to 15 parts of kaolin, 6 to 10 parts of Datong soil, 8 to 12 parts of calcite, 5 to 7 parts of copper oxide, 0.4 to 0.6 part of bone ash, 2.5 to 3.5 parts of tin oxide, 0.4 to 0.6 part of manganese oxide and 4 to 6 parts of zinc oxide. According to the copper-red glaze and a preparation method thereof, the copper-red glaze, which has a deep, stable, thick and bright color, a strong jade texture and good glossiness, can be fired through strictly controlling a sintering atmosphere and the content of each raw material in a glaze material.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a copper red glaze and a preparation method thereof. Background technique [0002] Jun porcelain is one of the five famous porcelains in the Song Dynasty in my country. It is famous for its unique kiln transformation art. The "copper red glaze" in Jun porcelain is famous for its crystal clear and even moisture, and has a high collection value. However, although the copper red glaze prepared by the existing formula and method for preparing copper red glaze can produce bright red color, the color is not deep, stable, thick and not bright enough, and the texture of jade is not strong. lower. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a copper-red glaze with deep, stable, thick and bright color, strong jade texture and good gloss. [0004] In order to achieve the above object, the technical ...
