Problems solved by technology

However, bone china porcelain is thin and brittle, with poor hardness and toughness, which limits the application of some decorative techniques on bone china.
Crystalline glaze is a kind of artistic glaze with gorgeous color and unique flavor. There are many patents related to crystallized glaze, but there is no report of crystallized glaze on bone china. Therefore, it is very necessary to study crystallized glaze on bone china. It will boost the prosperity of bone china and the formation of the brand

Embodiment Construction

[0012] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0013] A preparation method of zinc silicate crystalline glaze for bone china, comprising the following steps:

[0014] 1. Ingredients

[0015] Select Sinopharm analytically pure SiO2, analytically pure ZnO, analytically pure TiO2, analytically pure CuO, and add them to the basic glaze of bone china. The specific mass percentages are: SiO220%, ZnO20%, TiO21%, CuO1.5%, basic glaze 57.5% %.

[0016] 2. Preparation method

[0017] 1) The glaze slurry preparation process is as follows: Weigh the raw materials according to the formula, make the ratio of material: ball: water equal to 1:1.5:0.8, and then ball mill in the planetary ball mill for 30 minutes, pass through a 250-mesh sieve, and the sieve residue < 0.3%, adjust the concentration of the glaze slurry to be 53 degrees Baume.

[0018] 2) The glazing process is as follows: the clay body is ...

Abstract

The invention relates to a preparation method of zinc silicate crystal glaze for bone china, and belongs to the technical field of bone china production. According to the technical scheme, the method comprises the steps that in bone china basic glaze, a proper amount of SiO2 is added, a proper amount of seeding agents ZnO and TiO2 is added, and a proper amount of chromophoric reagent metallic oxide is added. All the components are weighed and mixed according to the formula, ball milling is performed, screening is performed through a 250-mesh sieve, the ratio of residues on the sieve is smaller than 0.3%, the sieved glaze is applied to a standby unglazed ware in a glaze spraying or glaze dipping method, and then the dried glazed ware is arranged inside a kiln and fired according to a specific firing curve to obtain a bone china crystal glaze product. The preparation method has the advantages that the preparation method for crystal glaze for bone china is creatively disclosed, the glaze surface with the complete crystal flower and the beautiful color is formed on the bone china and combined with the characteristics that the bone china is pervious to light, fine and smooth, the strong artistic effect is achieved, and the new requirement of the market is met.

Description

technical field [0001] The invention relates to a preparation method of zinc silicate crystal glaze for bone china, belonging to the technical field of bone china production. Background technique [0002] Bone china, referred to as bone china, scientifically known as bone china, is a kind of porcelain made of animal bone charcoal, clay, feldspar and quartz as basic raw materials, which are fired twice by high-temperature plain firing and low-temperature glaze firing. Bone china has become a high-grade porcelain favored by consumers because of its good light transmission, high whiteness, fine porcelain quality, and smooth glaze. It has long been used by nobles in various countries. However, bone china porcelain is thin and brittle, with poor hardness and toughness, which limits the application of some decorative techniques on bone china. Crystalline glaze is a kind of artistic glaze with gorgeous color and unique flavor. There are many patents related to crystallized glaze, ...
