Reverse osmosis shell texture ceramic and preparation method thereof

Abstract

The invention relates to the field of ceramic products and preparation methods thereof, in particular to reverse osmosis shell texture ceramic and a preparation method thereof. The product comprises a green body, a shell, spot metal glaze and cover glaze, the texture surface of the shell faces outwards and is buckled on the outer surface of the green body, and the cover glaze covers the surface of the green body; the spot metal glaze is arranged between the green body and the cover glaze. According to the invention, the permeable glaze permeates out of the shell filled with gaps, so that the shell is pink, the texture and the edge of the shell are clear and visible; then, the temperature is rapidly increased in a strong reduction stage, so that the glaze surface is rapidly molten, air holes are sealed, a reducing atmosphere cannot permeate into a blank, Fe2O3 in the blank cannot be fully reduced into FeO and is yellow, and the dotted metal glaze presents a metal color; finally, a ceramic form is finished to show a sand-yellow glaze surface with golden spot-shaped spots which are similar to golden spot-shaped spots on a sand beach with the shell-like textures, so that the sand-yellow glaze has unique aesthetic value.

Description

technical field [0001] The invention relates to the field of ceramic products and a preparation method thereof, in particular to reverse osmosis shell texture ceramics and a preparation method thereof. Background technique [0002] In order to present the shell texture on the ceramic surface, the traditional method is to directly paint the shell pattern on the surface of the body. This method is a flat drawing and lacks a three-dimensional effect. The glaze is fired, and the surface color of the shell will decompose and oxidize during the firing process. In the end, the shell can only appear white, and cannot show rich colors. When fired, the texture of the shell itself cannot be presented, and the colored glaze on the edge spreads outwards, resulting in unclear edges of the shell. In view of this, this case was born. Contents of the invention [0003] An object of the present invention is to solve at least the above-mentioned problems by reverse osmosis shell-textured ce...

[0002] In order to present the shell texture on the ceramic surface, the traditional method is to directly paint the shell pattern on the surface of the body. This method is a flat drawing and lacks a three-dimensional effect. The glaze is fired, and the surface color of the shell will decompose and oxidize during the firing process. In the end, the shell can only appear white, and cannot show rich colors. When fired, the texture of the shell itself cannot be presented, and the colored glaze on the edge diffuses and overflows, resulting in unclear edges of the shell. In view of this, this case arises
