Talc or talcum
Talc, a naturally occurring mineral, holds a significant place in various industries due to its unique properties and versatility. Composed of magnesium, silicon, and oxygen, talc is mined from deposits around the world, with notable reserves found in regions such as the United States, China, and Brazil. Talc forms through the metamorphism of pre-existing rocks, primarily rich in magnesium. The mineral’s characteristic softness and slippery feel can be attributed to its structure, which consists of layers of sheets held together by weak bonds. This structure allows talc to easily break into thin sheets or slide against each other, giving it its distinct tactile qualities.
