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

A method for preparing a carbon-golden metallic luster crystalline glaze. The source and composition of the glaze are (parts by mass): 25-30 parts of MnO2 are used as crystallization agents, 0.5-1.5 parts of MoO2 and 0.5-1.5 parts of V2O5 are used as crystals 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 and various metal oxides are used as colorants, and other ingredients are 30-38 parts of Pingjiang Potassium Feldspar, 5-12 parts of quartz produced in Fengyang, 5-10 parts of talc powder produced in Wuxi and 5-12 parts of boron frit produced in Yixing. After the glaze slurry is prepared and applied to the biscuit body, the temperature curve of the present invention is used for glaze firing. With a charcoal gold metallic luster and iridescent effect and crystal beauty. In addition, it has low cost, high glaze hardness, good wear resistance and corrosion resistance. It is a brand-new ceramic art glaze and can be used to decorate ceramic handicrafts.

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...
