Steatite, a talc-rich rock; chiefly talc, Mg₃Si₄O₁₀(OH)₂

AI-generated identification · may be incorrect

Small, pale gray-green, fine-grained piece with a dull to slightly waxy surface. Soapstone is very soft (about 1 on Mohs); the image alone does not confirm its identity or reveal crystal structure or specific gravity.

Physical properties

Formation & geological history

Forms through metamorphism and alteration of magnesium-rich rocks, commonly in Precambrian and younger metamorphic belts. The specimen’s age and source cannot be determined from the image.

Uses & applications

Soapstone is used for carving, countertops, laboratory benches, and heat-resistant components; this small piece appears to be a rough specimen rather than a finished object.

Geological facts

Talc-rich soapstone feels notably smooth or soapy and can usually be scratched with a fingernail.

Field identification & locations

Look for a soft, smooth feel and easy scratching; compare with a known specimen, since other pale rocks can look similar. Soapstone occurs worldwide, including Brazil, India, Finland, and the United States.
