Embodiment 1

[0034] A preparation method of secret color enamel, comprising the following steps:

[0035] (1) Weigh each raw material according to the following parts by weight: 55 parts of potassium feldspar, 15 parts of quartz, 10 parts of fluorite, 15 parts of plant ash, 1 part of titanium oxide, 2 parts of iron oxide, 2 parts of gold ore, and 1 part of marble ;

[0036] (2) The above-mentioned raw materials are fully pulverized and then mixed to obtain a mixed glaze;

[0037] (3) Put the mixed glaze into the ball mill, add water and ball mill to a fineness of 300 mesh, wherein the mass ratio of mixed glaze, ball and water is 1:1.8:0.9, the speed of the ball mill is 300r / min, and the ball milling time is 100min , to obtain glaze slurry;

[0038] (4) Apply the glaze slurry evenly on the bisque-fired blank. The glaze application method is glaze dipping. The glaze time is 3-5s, and the thickness of the glaze is 0.4-0.8mm. After the glazed blank is dried, it is put into the kiln for fir...

Abstract

The invention belongs to the technical field of glaze preparation, and particularly relates to secret-color porcelain glaze which is prepared from the following raw materials in parts by weight: 45-60parts of potassium feldspar, 12-20 parts of quartz, 7-15 parts of fluorite, 12-20 parts of plant ash, 1-3 parts of titanium oxide, 1-3 parts of ferric oxide, 1-3 parts of gold ore and 1-3 parts of marble. The invention also discloses a preparation method of the secret-color porcelain glaze. The preparation method comprises the following steps: (1) weighing the raw materials according to the proportion,(2) fully crushing the raw materials, and uniformly mixing to obtain a mixed glaze material, (3) adding the mixed glaze into a ball mill, and adding water for ball milling to obtain glaze slip,(4) uniformly applying the glaze slip to a biscuiting blank, drying the glazed blank, putting the dried glazed blank into a kiln for firing, heating to 1260-1300 DEG C in an oxidizing atmosphere in astepped heating manner, keeping the temperature for 60-80 minutes, and naturally cooling to room temperature, thereby obtaining the secret-color ceramic glaze. The secret-color porcelain prepared by the raw material ratio and the preparation method disclosed by the invention is good in coloring effect, uniform in glaze color, high in glossiness, high in hardness, free of cracks and high in yield.

Description

technical field [0001] The invention belongs to the technical field of glaze preparation, and in particular relates to a secret-color enamel and a preparation method thereof. Background technique [0002] Secret color porcelain is a fine product of traditional Chinese porcelain making technology. The word "secret color" first came from the late Tang poet Lu Guimeng's poem "Secret color Yue Qi". "Secret color" means "secret glaze formula", "secret color "Porcelain" is porcelain made by coating the surface of utensils with a secret glaze formula. The special glaze formula of secret color porcelain can produce the aesthetic effect of "ice-like" and "jade-like" on the appearance of porcelain. The combination with the carcass is particularly strong, so this formula is kept secret, and it is specially used for the firing of royal porcelain. It is named because of its secret production process. Excellent work. [0003] There are different opinions about what kind of color the "se...
