Enamel coated cast iron pot, referred to as enamel pot. Enamel is also called enamel, which is inorganic glass enamel painted on the surface of metal substrate. Silicate minerals, mainly composed of high-strength quartz and feldspar, have no toxic and side effects on human body. Enamel enamel on the metal surface can prevent metal from rusting, prevent metal from forming oxide layer on the surface when heated, and can resist the corrosion of various liquids. Therefore, in the process of cooking food with enamel pot, harmful dissolved substances will not be generated due to high temperature, and the acid and alkali resistance is good, and it will not react with food chemically. The cast iron pot is composed of iron and carbon. The natural cast iron material is heavier than ordinary metal materials. It is recognized as the best pot material with the advantages of fast and uniform heat conduction and good thermal insulation. The enamel pot is the combination of natural cast iron materials and high-quality enamel.
