CN102219561A - Production method of streaked glaze with leopard spots - Google Patents

Abstract

The invention relates to a production method of streaked glaze with leopard spots. In the method, main base glaze and auxiliary glaze are respectively produced and are applied on a green body in a mixed way, and the components of the main base glaze are potash feldspar, clinker, calcite, quartz, Guizhou soil, zinc oxide, manganese carbonate and calcined iron oxide red. The components of the auxiliary glaze are clinker, feldspar, calcite, zinc oxide and quartz. The components of the clinker are borax, quartz, potash feldspar, smashed glass powder and potassium carbonate. The clinker is treated with dry grinding firing for standby; the main base glaze material is subjected to dry grinding, the auxiliary glaze material is subjected to wet ball milling, the main base glaze material and the auxiliary glaze material are regulated to the same baume degree and are prepared according to the proportion that the main base glaze material to the auxiliary glaze material is 1 : 1-1.8, the green body is glazed by adopting a glaze spraying manner, and glaze thickness is 1.2mm; as the components of the two glazes include zinc, ferrum, manganese and other supersaturated crystallization materials, the glaze can be quickly produced by sintering in a tunnel furnace by the reaction of double layers of glazing color; and the obtained glaze surface is bright, has the color similar to that of leopard fur, and has excellent effect in decorating domestic porcelains.

Description

A kind of making method of leopard point line glaze

Technical field

The present invention relates to a kind of making method of leopard point line glaze.

Background technology

At present, in the porcelain industry, it is very important that base substrate is made moulding, the allotment of glaze more can demonstrate the attractive in appearance of product, the base substrate of same moulding is often because of the different visions to the human consumer of overglaze produce Different Effects, at the color on porcelain surface, attractive in appearance and user's that pattern directly has influence on product favorable rating, with on a kind of base substrate of device shape because of different glaze colors, and the human consumer is produced different visual effects.Making has pattern, as the glaze of animal skin spot color, need fill out glaze with Freehandhand-drawing, wastes time and energy, and efficient is not high.

Summary of the invention

The objective of the invention is to prepare and a kind ofly have the same glaze chromatic effect of leopard fur color and luster, can be in tunnel furnace fast burn till in 1180 ℃～1196 ℃, can reach the same leopard point line glaze of leopard fur color and luster.

The present invention is by main basic glaze, secondary glaze, frit is prepared respectively, remix imposes on the base substrate, by given prescription batching, because two kinds of glaze compositions contain zinc, iron, manganese, wait supersaturation crystallization raw material, by double-deck glaze colour response, go under 1180 ℃～1196 ℃ oxidizing atmosphere, to burn till in the quick tunnel furnace and promptly make the glaze light, have the glaze of color as the leopard fur.
