Ceramic worktop is calcined from natural silicate material at a high temperature of 1250 oC, and the surface is processed by imported corrosion resistant special glaze. Its physical and chemical properties are stable, the flame retardancy is quite good, the corrosion resistance is the best, and the scratch resistance is higher than the stone. The limit temperature is 1500 degrees, no moisture absorption, no deformation, and it has a very long service life. So it is very suitable for many special experimental conditions.
