Ceramic is a hard material formed by a series of physical and chemical reactions of clay raw materials, inert raw materials and flux raw materials after proper proportioning, pulverization, molding and high-temperature roasting. More common are: ceramic tea sets, ceramic plates, ceramic bowls, and a variety of ceramic living utensils.
The enamel is a kind of composite material that is coated with one or several layers of enamel on the surface of metal and is sintered and physically and chemically reacted to form a solid composite. The biggest benefit of doing so is corrosion resistance. More common examples are: enamel wok, enamel washbasin, etc.
How to distinguish between the two? First of all, enamel is coated on the metal surface with a layer of ceramic glaze and fired at a high temperature; enamel is only one layer on the metal surface, and the enamel industry requires good suspensibility. Once again, ceramics, which are mainly coated with a layer of ceramic glaze on ceramic bodies, are fired at high temperatures. The ceramics industry requires good plasticity, formability and whiteness of firing; refractory materials require high refractoriness, so chemically speaking, the composition of ceramics is not much different from the composition of rocks.
Therefore, it is concluded that these materials do not have any chemical materials and are almost harmless to the human body.
