Abstract

The invention discloses a method for preparing ceramics in which glazing and molding are carried out simultaneously. Ceramic blanks and glazes are respectively prepared into highly plastic mud materials, which are connected together by rolling, and then formed and sintered to obtain ceramic products. In addition, it also discloses a product prepared by the above-mentioned ceramic preparation method in which glazing and molding are performed simultaneously. In the present invention, glazing and molding are carried out at the same time, and the blank glaze is integrally formed without a special glazing device, which simplifies the production process, and the glaze color of the product is rich and colorful, which enriches the expression form of the glaze color of the ceramic product; the blank glaze has good bonding, and the glaze thickness of the product is uniform and controllable , to obtain a richer decorative effect.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a ceramic preparation method in which glazing and molding are performed simultaneously and a product thereof. Background technique [0002] Ceramics are an indispensable material and product in human production and life. Usually, there is a layer of glass-like quality on the surface of ceramic products, which is called glaze. The purpose of glazing is to improve the physical and chemical properties of the surface of the green body, increase the aesthetic feeling of the product, and improve the performance of the product. The preparation method of the existing ceramic products is mainly divided into three main processes: molding, glazing, and high-temperature sintering, and is mainly suitable for regular-shaped utensil-shaped products. According to the traditional glazing method, whether it is plastic forming rolling, spinning, extrusion, blanking process, or grouting...
