Talcum Powder – LR Grade, 1kg (French Chalk)

Talcum Powder, also known as French Chalk, is a fine, soft mineral powder supplied in a 1kg pack and manufactured to Laboratory Reagent (LR) grade. It is chemically known as hydrated magnesium silicate and is widely used in educational science laboratories due to its stability, softness, and characteristic physical properties.

Identified by CAS Number: 14807‑96‑6 and with no UN number, talcum powder is not classified as hazardous for transport when handled appropriately. Its very fine particle size and low hardness make it particularly useful for demonstrations and investigations involving mineral properties, friction, and materials science.

Supplied in a generous 1kg quantity, this product is suitable for repeated use across multiple lessons and year groups, making it a practical and economical choice for school laboratories and preparation rooms.
