Abstract

The invention discloses a high-hardness Jun porcelain sapphire glaze, which is characterized by being prepared from the following materials in parts by weight: 30 to 36 parts of melilite, 20 to 28 parts of quartz, 12 to 18 parts of calcite, 12 to 18 parts of wollastonite, 4 to 6 parts of calcined talc, 3 to 5 parts of zinc oxide, 0.5 to 1.5 parts of tin oxide, 0.5 to 1.5 parts of copper oxide, 0.3to 0.7 part of cobalt oxide and 3 to 5 parts of kaolin. A preparation method of the high-hardness Jun porcelain sapphire glaze includes the following steps: (1) after being crushed, the materials aremixed, put into a ball mill and milled, water is added, so that the mass concentration of the glaze material reaches 53 to 54 percent, wet milling is conducted for 7 to 8 hours, and wet-milled slurrypasses through a 250- to 320-mesh sieve, so that glaze slurry is obtained; (2) a green body is dipped in the glaze once or twice; (3) firing is carried out, wherein firing temperature is 1200 DEG C to 1240 DEG C.

Description

technical field [0001] The invention relates to the technical field of Jun porcelain manufacturing, in particular to a high-hardness Jun porcelain sapphire blue glaze and a preparation method thereof. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. Famous for its unique kiln transformation art, it has the reputation of "gold is priceless and Jun porcelain is priceless" and "a family with a lot of money is not as good as a piece of Jun porcelain". [0003] 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 F...
