Example Embodiment

[0022] The method for preparing ceramics using the red spot crystal glaze according to any one of the above claims of the present invention includes the following steps:

[0023] (1) Weigh the raw materials according to the glaze formula and put them into a ball mill for wet grinding. The weight ratio of material:ball:water during wet grinding is 1:2:0.6-1, and the glaze slurry obtained by grinding has a fineness of 200-300 mesh. The sieve residue is less than 1%, and the moisture content of the glaze slurry is 45-48%. It can be used after aging; the fineness of the glaze and the thickness of the glaze have a greater impact on the red spot crystal flower art glaze products. Only a few crystal flowers are scattered on the glaze surface after finishing. If the glaze is too thin, the crystal flower will appear small, and it will not grow up to form the required crystal flower size, which will affect the artistic effect of the crystal flower.

[0024] (2) Apply glaze on the biscuit, w...

[0028] Example 1

[0029] Glaze recipe:

[0030] 20 parts of albite, 10 parts of quartz, 10 parts of burnt talc, 1 part of calcite, 10 parts of ashes, 1 part of glass powder, 5 parts of barium carbonate, 5 parts of iron oxide, 0.5 parts of high-dielectric earth, 0.3 parts of fluorite powder.

[0031] Preparation:

[0032] (1) Weigh the raw materials according to the glaze formula and put them into a ball mill for wet grinding. The weight ratio of material:ball:water during wet grinding is 1:2:0.6, and the glaze slurry obtained by grinding has a fineness of 200-300 mesh sieve. The remainder is less than 1%, the moisture content of the glaze slurry is 45~48%, and it is used after aging;

[0033] (2) Apply glaze on the biscuit, with a thickness of 0.8mm, and dry after glazing;

[0034] (3) Put the dried body into a kiln. When firing, it takes 90 minutes from room temperature to 500°C, 60 minutes from 500°C to 950°C, 10 minutes from 950°C to 1100°C, and from 1100°C It takes 10 minutes to r...

Abstract

The invention discloses a red-spot crystalline glaze and a preparation method of ceramic adopting the same, belonging to the technical field of crystalline glazes. The glaze mainly comprises the following raw materials in parts by weight: 20-40 parts of albite, 10-20 parts of quartz, 10-20 parts of calcined talc, 1-10 parts of calcite, 10-25 parts of bone ash, 1-10 parts of glass powder, 5-15 parts of barium carbonate and 5-2 parts of iron oxide. The method comprises the following steps: (1) weighing the raw materials, performing wet grinding to obtain glaze slip, and aging; (2) glazing a biscuit firing billet, and drying; and (3) firing the dried billet in a kiln, and finishing the whole firing process of heating, high temperature keeping, cooling, low temperature keeping and extinction within 230-655 minutes. The invention aims to provide a red-spot crystalline glaze which is scientific in formula and favorable in use effect and a preparation method of ceramic adopting the same, and is used for red-spot crystalline glaze and ceramic manufacturing.

Description

technical field [0001] The present invention relates to a kind of glaze formula, more specifically, relates to a kind of erythema crystalline glaze. The invention also relates to a ceramic preparation method using the erythema crystalline glaze. Background technique [0002] The erythema crystal flower art glaze is a precious crystal art glaze, which is characterized by round erythema crystal flowers scattered on the brown or tan glaze surface, reflecting the shining light under the light, with a strong three-dimensional sense and The artistic effect is deeply loved by people. With the existing formula and process, there are disadvantages of high difficulty in firing, poor product repeatability and low yield during firing. Burning this kind of crystalline glaze often occurs the phenomenon that the whole kiln product particles are not harvested, which brings relatively large economic losses to the enterprise. Contents of the invention [0003] The object of the present i...
