Soapstone's formal name, for when you want geology to sound expensive.

means A soft, dense metamorphic rock made mostly of talc, prized for carving because it's workable with hand tools yet durable enough to hold heat and shape.

from From Greek 'stear' (στέαρ), meaning tallow or solid fat — the same slippery, fatty association that gives soapstone its common name. The '-ite' suffix is the standard mineralogical tag slapped onto rock and mineral names, so 'steatite' literally reads as 'fat-stone,' a nod to its greasy, soap-like feel rather than any culinary origin.
