Starry sky glaze formula and firing manufacturing method

Abstract

The invention discloses a starry sky glaze formula and a firing manufacturing method, the starry sky glaze formula comprises a ground glaze material and a cover glaze material, the ground glaze material comprises the following raw materials in percentage by weight: 15% of potassium feldspar, 15% of albite, 23% of quartz, 7.5% of kaolin, 3% of dolomite, 5.5% of calcium carbonate, 5% of barium carbonate, 8% of glass, 9% of zirconium silicate and 9% of black pigment; the cover glaze is prepared from the following raw materials in percentage by weight: 16% of A-38 feldspar, 16% of albite, 3.6% of Hunan black pottery clay, 1% of zinc oxide, 3% of talc, 2% of magnesium carbonate, 1.2% of calcium borate, 40% of bone ash, 4% of ferric oxide, 3.2% of cerium oxide, 4% of boron carbonate and 6% of phosphorescent powder. The preparation method is simple, the surface of the prepared starry sky glaze jun porcelain can refract a colorful glaze effect under light, the yield is high, and the ornamental value is high.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a starry sky glaze formula and a firing production method. Background technique [0002] Glaze has been widely used in people's daily life because of its good smoothness. The key to Jun porcelain lies in the glaze. Different firing processes produce different changes in glaze color, and the formula of glaze also affects the outer color of Jun porcelain. An important factor is also the key factor that causes Jun porcelain to enter the kiln with one color and exit the kiln with various colors. In the prior art, there are few formulas and preparation methods for starry sky glaze, which is not easy to fire, and the product scrap rate is high. The product has low mechanical strength, high energy consumption, high production cost, and it is difficult to realize the good application of starry sky glaze on Jun porcelain, thereby limiting the artistic appreciation and commercial value of...
