Embodiment 1

[0018] Glaze quality formula: 21.99 parts of potassium feldspar, 9.23 parts of calcite, 3.40 parts of kaolin, 5.38 parts of aluminum oxide, 2.00 parts of basic copper carbonate, and 1.4 parts of titanium dioxide.

[0019] Firing method: After the above ingredients are mixed, according to the mass ratio of glaze, porcelain ball milling balls, and water as 1:2.5:0.8, ball mill for about 50 hours, and then the glaze slurry passes through a sieve with an aperture of Φ0.061mm (250 mesh), The remaining 0.02% to 0.06% of the sieve can be transferred to the slurry storage tank for standby. Glazing; before glazing, use a sieve with an aperture of Φ0.154mm (100 meshes) to filter, put an iron-absorbing rod in the sieve, pass the glaze through the iron-absorbing rod to remove iron, and then filter through the sieve to remove mud and impurities. The glaze slurry is adjusted to a specific gravity of 1.51, and the dust on the surface of the ceramic body is removed with clear water before gla...

Embodiment 2

[0023] Glaze quality formula: 21.99 parts of potassium feldspar, 9.23 parts of calcite, 3.40 parts of kaolin, 5.38 parts of aluminum oxide, 1.00 parts of basic copper carbonate, and 1.4 parts of titanium dioxide.

[0024] Firing method and firing mode are the same as embodiment 1.

[0025] Copper element is the main coloring agent in the glaze of this patent, so in Example 2, 0.5 part of basic copper carbonate, under the situation of copper raw material reduction, the light turquoise of the glaze surface appears sluggish, sour.

Embodiment 3

[0027] Glaze quality formula: 21.99 parts of potassium feldspar, 9.23 parts of calcite, 3.40 parts of kaolin, 5.38 parts of aluminum oxide, 5.00 parts of basic copper carbonate, and 1.4 parts of titanium dioxide.

[0028] Firing method and firing mode are the same as embodiment 1.

[0029] Copper raw materials have a wide range of color development, and the amount seriously affects the color development of the glaze. When the copper content in the glaze reaches 5 components, the glaze will appear opacified, unsightly black, and appear insoluble and dull.

Abstract

The invention provides a bronze green crystalline glaze which is prepared from the following raw materials in parts by weight: 20-25 parts of potash feldspar, 8-10 parts of calcite, 2-5 parts of kaolin, 4-8 parts of aluminium oxide, 1-5 parts of basic cupric carbonate and 0.5-2 parts of titanium dioxide. The bronze green crystalline glaze has the beneficial effects that a bronze green porcelain product with a strong and rich artistic effect can be obtained according to the formula of the glaze and the firing method provided by the invention, the bronze green porcelain product is exquisite and beautiful, the formula is simple, the operation is convenient and the cost is low.

Description

(1) Technical field [0001] The invention relates to a bronze green crystalline glaze and a method for firing the bronze green crystalline glaze by using the glaze. (2) Background technology [0002] Coloring and glazing on the surface of ceramic products is an effective means to increase the texture and beauty of ceramic products, and the artistic effect of each glaze color or color is different. At present, there are various glaze colors, Designs and colors or their combination are mainly developed according to the needs of the market. In the current market, there is an atmosphere of returning to the ancient times and pursuing nature, and many things pay attention to a simple and generous artistic effect. The ceramic industry is no exception. Copper green can give people an ancient, long-standing, generous, and simple feeling. If the pattern is made on the surface of ceramic ware in the form of glaze, it will make consumers feel very retro. No such literature reports wer...
