Abstract

The invention discloses a blue composite transmutation glaze material and a method for preparing transmutation glaze ceramic by adopting the glaze material. A ground coat is prepared from the following materials in percentage by weight: 18 to 38% of feldspar, 0 to 20% of frit, 5 to 14% of calcite, 10 to 12% of calcined kaolinite, 6 to 12% of raw kaolinite, 4 to 13% of quartz, 12 to 18% of wollastonite, 6 to 12% of talc, 3.5 to 6.5% of aluminum oxide, 6 to 12% of ferric oxide, and 0.5 to 3.5% of cobalt sesquioxide; a surface coat is prepared from the following materials in percentage by weight:10 to 30% of feldspar, 0 to 30% of frit, 3 to 20% of calcined zinc oxide, 5 to 12% of calcite, 0 to 10% of dolomite, 6 to 12% of raw kaolinite, 8 to 22% of quartz, 10 to 23% of calcined kaolinite, and 2 to 8% of titanium dioxide; a blank is prepared from the following materials in percentage by weight: 5 to 20% of albite, 10 to 30% of potassium feldspar, 5 to 25% of quartz, 40 to 60% of kaolin, 0to 10% of aluminum oxide, and 0 to 7% of a plasticizer; during preparation, the blank is subjected to ball milling, filter pressing and dehydration to obtain a mud cake, then a rough blank is obtained according to the shape of the ceramic, and finally the rough blank is subjected to firing, ground coat soaking and surface coat soaking to obtain a glaze blank.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a blue composite kiln-changing glaze glaze material and a method for preparing kiln-changing glaze ceramics by using the glaze material. Background technique [0002] Glaze is a thin glassy layer covering the surface of the ceramic body. Its surface is smooth and shiny, and it is impervious to water and not easy to stain. It can improve the physical properties of the ceramic body and enhance the appearance of ceramic products. [0003] As a kind of artistic glaze, kiln-changing glaze, because the glaze contains a variety of color elements, after oxidation or reduction, it can show unexpected glaze color effects after it comes out of the kiln. Because of its unexpected glaze color and special shape, it is widely loved by people. . Due to the uniqueness of kiln-changing glazes and broad market prospects, kiln-changing glazes of many hues have appeared on the market, b...
