Abstract

The invention relates to a technology of a daily-use double-layer ceramic bowl, which belongs to the field of products made of ceramic material, and the daily-use double-layer ceramic bowl comprises a ceramic bowl body and is characterized in that the bowl body comprises an inner layer and an outer layer, the upper edges of the two layers are combined together, support legs are arranged at the outer bottom of the bowl body, and the bowl body is made of industrial ceramics; and the preparation method comprises material preparation, molding and firing, and is characterized in that the molding method by slip casting is adopted for molding, the outer bottom is molding alone, and the outer bottom is combined with the bowl body by adopting the bonding way. The daily-use double-layer ceramic bowl can realize thermal insulation and avoid scalding hands; furthermore, the strength is high, the transportation is convenient, the service life is long, the decoration is convenient, the daily-use double-layer ceramic bowl is healthy and environment-friendly, and the product grade is high; and the preparation method is scientific, reasonable, simple and easy to operate.

Description

technical field [0001] The invention relates to a double-layer ceramic bowl for daily use and a preparation method thereof, belonging to the field of ceramic material products. Background technique [0002] With the improvement of national life, the requirements for household products are getting higher and higher. People are no longer limited to the practicality of supplies, but also care about their taste. This is mainly reflected in the aesthetics of products, cultural connotations, and exquisite production. As a necessity in people's daily life, bowls have higher and higher requirements for their quality. They are no longer limited to being ordinary containers, but also require other functions. Under this background, the double-layer bowl was born in time, but the double-layer bowl on the market is generally made of stainless steel. If traditional daily-use ceramics are used to make double-layer bowls, the strength will be low, which is not conducive to transportation, ...
