Description

technical field [0001] The invention belongs to the technical field of daily-use ceramic products, and more specifically relates to a white ceramic product that can be used in an open fire and a preparation method thereof. Background technique [0002] Chinese porcelain has a long history and there are many varieties. In addition to the noble and elegant blue and white porcelain and the colorful colored porcelain, the simple and elegant white porcelain is also a variety that people love. What it shows to people is the natural beauty.

Problems solved by technology

Existing white porcelain is mostly used in porcelain carving art porcelain such as porcelain Guanyin and display porcelain such as vases and incense burners. Due to its soft texture, thick glaze and poor heat resistance, it cannot be used on open flames, and it is easy to burst when exposed to water after heating. Therefore, the popularization and application of white porcelain is limited.

[0004] In order to solve the above problems, the Chinese invention patent application with the application publication number CN108530022A discloses a suet jade white porcelain that can be used for open flames and its preparation method. It adds a large amount of spodumene to the blank and glaze as a heat-resistant raw materials, but the large amount of spodumene will affect the color effect of white porcelain, and will also lead to an increase in cost

The Chinese invention patent application with the application publication number CN109437834A discloses a kind of unglazed heat-resistant white jade porcelain and its preparation method, which completely solves the problems of glaze cracking or chipping due to the lack of glaze in the whole body, but the unglazed white porcelain products After a long time of use, it is inevitable that there will be color absorption, and the appearance will no longer be beautiful
