Talc
Talc is a soft, silicate mineral composed primarily of magnesium, silicon, and oxygen, with the chemical formula Mg₃Si₄O₁₀(OH)₂. It is the softest mineral on the Mohs scale of hardness, with a rating of 1, meaning it can be easily scratched with a fingernail. Due to its unique properties, talc is used in various industrial, cosmetic, and medical applications. Talc is used in the production of ceramics, as it helps reduce the firing temperature and improves the glaze properties. It also adds to the durability and smoothness of ceramic products.
