Overview
A metamorphic rock dominated by talc, soft enough to scratch with a fingernail and smooth enough to feel like soap. It is inexpensive, widely available, and shaped with woodworking tools rather than masonry ones, which makes it the standard recommendation for a first piece. The cost is that it abrades away quickly and holds no fine edge for long.
Using it
- Treat it like hardwood: rasps, files, scrapers, and a coarse saw to block out.
- Because it is so soft, mistakes accumulate quickly. Work in small increments.
- It polishes to a warm, almost waxy sheen with nothing more than a cloth and patience.
- The classic first project: a simple organic form, worked entirely by hand.
Safety notes
- Soapstone dust is fine, pervasive, and often contains tremolite or quartz. A P2/P95 mask is not optional.
- Talc dust is extremely slippery on a workshop floor. Extract at the tool and clean with wet methods.
- It abrades fast, so blades and rasps dull quietly. Check edges often.
