Abstract

A preparation method of copper-black metal glaze is characterized in that: a glaze material comprises the following sources and components (by mass): 15-25 parts of potassium feldspar powder, 6-15 parts of quartz powder, 10-17 parts of calcite, 1-5 parts of processed talc, 4-10 parts of kaolin, 10-20 parts of zinc oxide, 30-85 parts of medium-temperature frit, 5-10 parts of copper oxide, 0.1-1 part of cobalt oxide, 1-4 parts of ferric oxide and 2-5 parts of a black pigment; after glaze slurry is obtained, glaze firing is carried out in accordance with the temperature of the preparation method; and a glazed product has a bright glazing surface, and also has art effects of copper-black metal color.

Description

A kind of preparation method of copper ferrous metal glaze

Technical field

The present invention relates to a kind of preparation method of copper ferrous metal glaze.

Background technology

Ceramic has become more and more general daily product, along with social progress, more and more higher with people's standard of living, the human consumer is also more and more higher for the esthetic requirement of ceramic product, yet the critical material that plays modification effect for ceramic product is glaze, and existing glaze roughly is divided into according to classification and purposes: 1, lead glaze and leadless glaze; 2, raw glaze and fritted glaze; 3, once-firing or twice firing glaze; 4, tableware, ceramic tile, glaze etc. for snitaryware, traditional ceramic surface is all too much not modify or complex pattern, but along with the aesthetic raising of people, the porcelain that carries out metal-imitation glaze, marble grain texts at ceramic surface is more and more welcome, therefore, stability, diversity, glaze decoration, the pattern decoration for ceramic glaze become the target that each ceramic producer is pursued.

Summary of the invention

The invention provides the preparation method of copper ferrous metal glaze, make the product after burning till there is the glaze light, be the artistic effect of the metal glaze of copper black.

The present invention is achieved in that a kind of preparation method of copper ferrous metal glaze, the source of glaze and consist of (mass parts): adopt the feldspar in powder of 15～25 parts, 6～15 parts of silica powders, 10～17 parts of calcites, 1～5 part of ripe talcum, 4～10 parts of kaolin, 10～20 parts of zinc oxide, warm frit in 30～85 parts, 5～10 parts of cupric oxide, 0.1～1 part of cobalt oxide, 1～4 part of ferric oxide, 2～5 parts of black pigments.

The glaze slip preparation: the compositing formula by above-mentioned glaze takes respectively raw material, and in raw material: the ratio of ballstone: water=1:1.5:0.5～0.6 is pulverized in ball mill, Ball-milling Time is 12～20 hours, when the glaze fineness reached 180 mesh sieves, and gets final product during the concentration of furnishing 45～60 degree Beaume.

After glaze slip imposes on the biscuiting base substrate, the glaze layer thickness is controlled at 0.3～0.6 mm.

The glaze firing technique adopted is: be placed in the oxidizing atmosphere of 1180～1200 ℃, burning till frequency is 22～24HZ, and firing period is 4～5 hours, and soak 20～30 minutes, finally naturally cool to room temperature, obtains product.

The invention has the beneficial effects as follows:

1, glaze light, have again the artistic effect of copper ferrous metal look;

2, raw material sources are extensive, burn till rear hardness of glaze surface high, and wear resistance and good corrosion resistance are good ceramic artistic glazes.

Embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only, in order to explain the present invention, be not intended to limit the present invention.

A kind of preparation method of copper ferrous metal glaze, the source of glaze and consist of (mass parts): adopt the feldspar in powder of 15～25 parts, 6～15 parts of silica powders, 10～17 parts of calcites, 1～5 part of ripe talcum, 4～10 parts of kaolin, 10～20 parts of zinc oxide, warm frit in 30～85 parts, 5～10 parts of cupric oxide, 0.1～1 part of cobalt oxide, 1～4 part of ferric oxide, 2～5 parts of black pigments.

The glaze slip preparation: the compositing formula by above-mentioned glaze takes respectively raw material, and in raw material: the ratio of ballstone: water=1:1.5:0.5～0.6 is pulverized in ball mill, Ball-milling Time is 12～20 hours, when the glaze fineness reached 180 mesh sieves, and gets final product during the concentration of furnishing 45～60 degree Beaume.

After glaze slip imposes on the biscuiting base substrate, the glaze layer thickness is controlled at 0.3～0.6 mm.

The glaze firing technique adopted is: be placed in the oxidizing atmosphere of 1180～1200 ℃, burning till frequency is 22～24HZ, and firing period is 4～5 hours, and soak 20～30 minutes, finally naturally cool to room temperature, obtains product.

These are only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
