Furnace transmutation glaze dolomitic pottery and preparation technique thereof

Abstract

The invention provides a furnace transmutation glaze dolomitic pottery which comprises a base glaze and a surface glaze, wherein the base glaze is directly applied onto the surface of a dolomitic pottery body, and the surface glaze is applied onto the surface of the base glaze; the base glaze comprises the following components in parts by weight: 70-75 parts of low-temperature leadless fusion cake, 5-6 parts of coloring oxide, 12-14 parts of calcium carbonate, 3-5 parts of alkaline earth metal compound and 5-6 parts of kaolin; and the surface glaze comprises the following components in parts by weight: 85-90 parts of low-temperature leadless fusion cake, 2-5 parts of zinc oxide, 2-5 parts of titanium oxide, 0-2 parts of coloring oxide and 5-6 parts of kaolin. The invention also provides apreparation technique of the furnace transmutation glaze dolomitic pottery. The firing temperature of the furnace transmutation glaze dolomitic pottery is 1080-1100 DEG C, and the firing time is 8-12hours; and thus, the invention has the advantages of low firing temperature, short time, lower energy consumption, resource saving, energy saving, emission reduction, low carbon and environmental protection, and lowers the production cost of the product. The reaction intensity of the glaze layer can be controlled by adjusting the proportion of glaze materials and the thickness of the glaze layer,thereby preparing various dolomitic pottery furnace transmutation glazes with different glaze effects, such as bundles and the like.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a kiln-changed glazed dolomite pottery and its manufacturing process. Background technique [0002] The traditional kiln-changing glaze is fired at medium and high temperature, the firing temperature is above 1200°C, and the firing time is mostly more than 12 hours. The high firing temperature, long time, and large energy consumption lead to high cost and are not environmentally friendly; There are light-weight Baiyun pottery kiln-changing glazes with a single glaze effect and monotonous varieties, which cannot cater to the needs of consumers with different personalities. It is very necessary to seek a light-weight Baiyun pottery kiln-changing glaze that can be fired quickly at low temperature and can control different glaze effects and its manufacturing process. Contents of the invention [0003] In order to solve the technical problems of high firing temperature, long firin...
