Embodiment approach

[0019] According to the performance indicators to be achieved by the charcoal golden metallic luster crystalline glaze, the implementation plan for the process route, materials and production methods is as follows:

[0020] The first is to prepare flat plates, bowls and other stoneware tableware biscuits, and its chemical composition is (parts by mass): SiO 2 60~75, Al 2 o 3 18~30, Fe 2 o 3 1.0~2.0, CaO 0.5~1.5, MgO 0.1~0.4, K 2 O is 1.0~3.0, Na 2 O is 0.1~0.8, others 5~15. The biscuit firing temperature of the green body is 950-1050°C, and the water absorption rate is 1.5%-3.5%. The green body needs to be polished and cleaned before use.

[0021] Then there is the selection of raw materials and the production of glaze slurry. The source and composition (parts by mass) of the glaze are: 25-30 MnO 2 It is crystallization agent, MoO of 0.5~1.5 2 and a V of 0.5 to 1.5 2 o 5 As a crystallization accelerator, 2-4.5 CuO, 2.5-5 Fe 2 o 3, 3~7 ZnO and 0.5~2.5 NiO and other...

Abstract

The invention relates to a preparation method of a carbon-golden metallic luster crystalline glaze. The carbon-golden metallic luster crystalline glaze comprises the following component in parts by mass: 25-30 parts of MnO2 as crystallizing agent, 0.5-1.5 parts of MoO2, 0.5-1.5 parts of V2O5 as crystallization accelerator, 2-4.5 parts of CuO, 2.5-5 parts of Fe2O3, 3-7 parts of ZnO and 0.5-2.5 parts of NiO as colorants, 30-38 parts of potash feldspar produced in Pingjiang, 5-12 parts of quartz produced in Fengyang, 5-10 parts of talcum powder produced in Wuxi, and 5-12 parts of boron fusion cake produced in Yixing. The prepared glaze slip is applied onto a biscuited green body, and subjected to glaze firing according to the temperature curve in the invention. The carbon-golden metallic luster crystalline glaze has carbon-golden metallic luster, rainbow effect and beautiful appearance of crystals. Besides, the carbon-golden metallic luster crystalline glaze has the advantages of low cost, high glaze hardness, high wear resistance and high corrosion resistance, is a brand new glaze of ceramic art, and can be used for decorating ceramic artware.

Description

technical field [0001] The invention relates to a method for preparing a carbon-gold metallic luster crystal glaze. Background technique [0002] Metal luster crystalline glaze is a kind of ceramic glaze that produces tone and luster on the glaze surface, which is similar to some metal and contains crystals. It is a new type of ceramic art glaze developed in recent years. It not only has the luster effect of metal and the aesthetic feeling of crystal, but also has the characteristics of low cost of ceramic glaze, high hardness of glaze surface, good wear resistance and corrosion resistance. The metallic luster is due to the strong reflection of light by the dense interweaving of fine needle-like crystals, which makes the glaze appear thick, solid, luxurious and rich. There are many reports about metallic luster crystalline glazes, but there is no report on carbon-gold metallic luster crystalline glazes. [0003] CN1521145 discloses a metal luster crystalline glaze for arc...
