The material of the glass itself comes from nature, and the harmful substances have volatilized after high temperature in the production process, so the safety is high, and the glass has high temperature resistance and good thermal conductivity. Ceramic materials have a wide range of applications, such as acid resistance, alkali resistance, oil resistance, high temperature resistance, low temperature resistance and high safety.
