Secret-color porcelain glaze and preparation method thereof

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...

Problems solved by technology

[0009] Because the secret color porcelain is too rare in the world, at present, the coloring effect obtained by using the existing technology and preparation method is poor, the glaze color is uneven, and the gloss is low, which cannot meet the requirements of mass production; moreover, people in the world pay more and more attention to food safety. In today's healthy world, ordinary porcelain does not have the function of health preservation, and its market competitiveness is not high. It must be improved in technology and formula to make it beautiful, practical, healthy, and health-preserving.
