Abstract

Golden-spot blue glaze is prepared from the following raw materials in parts by weight: 62 to 68 parts of melilite, 10 to 16 parts of quartz, 12 to 18 parts of calcite, 1.5 to 2.5 parts of stannic oxide, 0.5 to 1.5 parts of banhuashi (a kind of lean iron ore), 0.5 to 1.5 parts of bovine-derived power, 1.5 to 2.5 parts of talc and 0.5 to 1.5 parts of blue powder. Compared with the prior art, through scientific and reasonable raw material ratio and control on firing technique, the blue glaze with golden spots is prepared, the blank that the blue glaze has no golden spots is filled, and a new variety is provided for blue glaze jun porcelain; in addition, the golden-spot blue glaze prepared according to the invention is gorgeous, bright and smooth, the glaze surface has no pores and glaze missing, the firing temperature is convenient to control, and the rate of finished products is high, reaching 90% or above.

Description

technical field [0001] The invention relates to a glaze, in particular to a golden spot blue glaze. Background technique [0002] Jun Porcelain is one of the five famous kiln porcelains of the Song Dynasty in my country. It is a treasure in the traditional Chinese porcelain making process. It is famous all over the world for its unique kiln transformation art. The "blue glaze" in Jun porcelain has a blue glaze color like the deep sea, and the glaze surface is uniform and stable in color. However, the glaze formula and firing process of the existing blue glaze firing blue glaze has a single glaze color and no gold on the glaze surface. spot. Contents of the invention [0003] The purpose of the present invention is to provide a kind of golden spot blue glaze for solving the deficiencies of the prior art. [0004] The purpose of the present invention is achieved with the following technical solutions: [0005] A golden spot blue glaze, which is prepared from the following...
