On the other hand, chlorite talc, rich in magnesium, is favored for its ability to improve the thermal shock resistance of ceramic products. This type of talc is often used in the manufacturing of sanitary ware and dinnerware. In summary, the choice between steatite and chlorite talc depends on the specific requirements of the ceramic product.
