[0022] A method for preparing ceramics using the erythema crystalline glaze described in any one of the above claims of the present invention comprises the following steps:

[0023] (1) Weigh each raw material according to the glaze formula, put it 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 fineness of the glaze slurry obtained by grinding is over 200~300 mesh The sieve residue is less than 1%, and the moisture content of the glaze slurry is 45-48%. It is reserved after being stale; the fineness of the glaze and the thickness of the glaze have a great influence on the product of the erythema crystal flower art glaze. Too fine glaze is not conducive to the formation of crystal nuclei. After the glaze is finished, there are only a few crystal flowers scattered on the glaze surface. If the glaze is too thin, the crystal flowers will be small, and it will not be easy to grow to form the required crystal fl...

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...
