Background

The Chinese culture is profound and profound, the inheritance is long-lasting, and the world is a highly famous etiquette, and China stands by the agricultural countries and people eat food as days, so the etiquette on the dining table is very exquisite, and the culture of tableware is very representative. As early as the age of the stone novelties, people have come to understand that bowls are used for eating, most of the traditional materials used for making the bowls are porcelain, and metal accounts for a certain proportion.

In the diet mode, Chinese people also have own characteristics, namely poly food. The origin of poly-food is very early, and as can be seen from the discovery of a plurality of underground cultural heritages, the ancient cooking rooms and poly-food places are unified, the cooking rooms are arranged in the center of a house, skylight smoke is formed at the upper part, bonfire is arranged at the lower part, cooking is carried out on the fire, and eaters surround the fire to poly-food. This food accumulation is ancient until the coming. The long-term circulation of food-gathering system reflects Chinese meal in actual life by attaching importance to the relationship of kindness and family concept in dietary ways,

unlike the ancient fire-surrounding gathered food, the modern gathered food is no longer close to open fire, and if the temperature is in a cold environment, the food can be cooled quickly, so that the taste of the food is greatly influenced; therefore, people also invent a mode of an alcohol stove and the like for heating easily cooled food, but certain danger exists, and the attractiveness of the dining table is influenced. Therefore, the problem that the taste of food is influenced because the food is easily cooled is solved without damaging the ornamental value of the ceramic ware which is popular among Chinese people for thousands of years, and the method has great research value.
