French Chalk is a soft, white, powdery substance made from TALC and used for marking on surfaces such as paper, wood, or stone. It is also known as talcum powder, TALC, or chalk. The term 'French Chalk' is derived from the French word 'craie, ' which means chalk. TALC is a mineral composed of hydrated magnesium silicate and is the main component of French Chalk. It is often used in cosmetics, paint, and other industrial products.
