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 treatedwith 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
technical field [0001] The invention relates to a preparation method of leopard dot pattern glaze. Background technique [0002] At present, in the porcelain industry, the shape of the body is very important, and the deployment of glaze can better show the beauty of the product. The body of the same shape often has different effects on the vision of consumers due to different glazes. The color and pattern of the surface directly affect the beauty of the product and the user's liking. The same shape of the body has different visual effects for consumers due to different glaze colors. Making glazes with patterns, such as animal fur spots and colors, requires hand-painted glazes, which is time-consuming and laborious, and the efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to prepare a leopard-spot pattern glaze which has the same glaze color effect as leopard fur, can be fired in a fast tunnel kiln at 1180°C to 1196°C, and ...
