Soapstone, also known as steatite or soaprock, is a metamorphic rock composed primarily of talc with varying amounts of other minerals like chlorite, pyroxenes, micas, amphiboles, and carbonates. Talc is the main constituent of soapstone, typically comprising 30% to 80% of the rock

Soapstone is primarily composed of talc (Mg3Si4O10(OH)2), a soft mineral with a greasy feel. The amount of talc in soapstone determines its characteristics, such as color and hardness.

Soapstone is known for its smooth texture, high heat resistance, and ability to withstand acidic and alkali chemicals. It is typically gray, green, or bluish in color, but can also be found in shades of brown, yellow, or white depending on mineral impurities.
