One is fired from soil and the other is painting on metal
The raw materials, production process and craftsmanship of ceramics and enamel are different, so they belong to two different appliance materials.
Ceramics is the general term for pottery and porcelain. Generally, it is made by mixing, forming, and calcining under high temperature conditions using pottery clay or porcelain clay as the raw material. In the home life of the people of our country, the bowls and plates used for daily meals, and the tea sets for drinking tea are generally made of pottery and porcelain.
The enamel is an inorganic glass enamel, also known as enamel, which is made with metal as the base body through enameling, drying, firing, and inspection steps at high temperatures. In recent years, there have been fewer and fewer traces of enamel products in daily life, but if you pay enough attention, you can often see them in some film and television dramas that show life in the 70s and 80s, and the representatives of them are washing their faces. Most of the tableware used in the canteens of the army, state-owned factories, etc. also choose enamel.
