Abstract

The invention discloses a red glaze and a preparation method thereof, and relates to the technical field of glaze production. The red glaze is characterized by being prepared from the following raw material components in parts by weight: 30 to 34 parts of glaze stone, 22 to 24 parts of kiln slag, 11 to 12 parts of lead crystal material, 10 to 12 parts of white glass, 1 to 2 parts of pink salt, 1 to 2 parts of realgar, 1 to 2 parts of wine ferrous fluoborate, 10 to 12 parts of green glass, 2 to 3 parts of lime-ash soil and 3 to 4 parts of cement. The preparation method comprises the following steps: weighing all the component raw materials according to the proportions, and then respectively performing wet grinding; mixing the ground materials, and then screening through a 200 to 400-mesh screen; during glazing, soaking or pouring is required to be performed on an unglazed porcelain body for once, and after drying, spraying by using glaze slip containing 50 percent of water for three times, wherein a glaze layer is thick in the upper part and thin in the lower part, the glaze thickness is 1.5 to 2.0mm. The red glaze is pure in color, and easy to fire, and spots and knots are not liable to occur.

Description

Technical field: [0001] The invention relates to the technical field of glaze production, in particular to a red glaze and a preparation method thereof. Background technique: [0002] Ceramic is a general term for pottery, stoneware and porcelain. All utensils made of clay and china clay, which are two different types of clay, can be called ceramics. In the prior art, the red glaze mainly depends on increasing the content of the pigment, and then the intensity and hardness of the pigment symmetrical porcelain have certain adverse effects, the color is not pure and uneven, and it is easy to form spots or nodes after firing. Invention content: [0003] The technical problem to be solved by the present invention is to provide a red glaze with pure color, easy firing, and not easy to cause spots and nodes, and a preparation method thereof. [0004] The following technical solutions are adopted to solve the technical problems: [0005] A red glaze is characterized in that: i...
