Abstract

The invention discloses copper-red glaze for Jun porcelain. The copper-red glaze is prepared from raw materials in parts by weight as follows: 26-34 parts of melilite, 6-10 parts of white feldspar, 10-14 parts of kaolin, 6-10 parts of talc, 22-26 parts of quartz, 10-14 parts of calcite, 0.9-1.1 parts of copper oxide, 1-3 parts of zinc oxide, 1.1-1.3 parts of silicon carbide and 1-3 parts of wood ash. The preparation method of the copper-red glaze for the Jun porcelain comprises steps as follows: (1) the raw materials are crushed, mixed and put in a ball mill for ball milling, water is added, so that the mass concentration of the glaze reaches 52%-53%, wet grinding is performed for 15-16 h, slurry obtained through wet grinding is sieved by a 200-300-mesh sieve, and glaze slurry is obtained;(2) glazing is performed in a glaze dipping manner, wherein the glazing thickness is 0.8-1.2 mm; (3) firing at the temperature of 1,260-1,300 DEG C is performed.

Description

technical field [0001] The invention relates to the technical field of Jun porcelain manufacturing, in particular to a Jun porcelain copper red glaze and a preparation method thereof. Background technique [0002] Jun Porcelain is a unique national treasure porcelain in Shenhou Town, Yuzhou City, Xuchang City, Henan Province. With its simple shape, exquisite craftsmanship, complex glaze matching, and the magical kiln transformation of "one color in the kiln, thousands of colors in the kiln", the scenery of lakes and mountains, clouds and clouds Fog, human, animal, flower, bird, insect, fish, etc. are known as the first of the "Five Famous Porcelains" in China. [0003] Red is the most expensive ceramic decoration, and there are many types of red glaze, among which copper red glaze has the longest history. Copper red glaze is a precious product developed after celadon glaze. It matured in Henan Jun kiln in the Northern Song Dynasty, and was inherited and developed by Jingdez...
