We use high-quality ceramic materials, which are second only to diamond in wear resistance and hardness. The unique non-metallic property does not produce pores and effectively resists bacterial growth. Its thermal conductivity is much lower than that of steel, and the low heat can well retain the aroma.
The color is white, with the noble texture of jade. In addition, it is non-toxic, pollution-free, non-oxidizing, heavy metal-free, corrosion-resistant, wear-resistant, healthy and environmentally friendly, and washable. Ceramics can be used for grinding salt, pepper and other purposes.
The following are the performance parameters of our ceramic materials, for your reference.
