Soapstone countertops: The dark countertops and sink in this photo are made from soapstone. Soapstone is heat resistant, stain resistant, nonporous, and resistant to attack from acids and bases. It is often used as a natural stone countertop in kitchens and laboratories.
Soapstone's texture resembles a dry bar of soap and is extremely malleable. It will easily form a shape with little force. Soapstone is so soft that you can carve it with harder rocks you find in your backyard; you can even use your fingernail to carve it. It also comes in many colors like grey, green, and black. Use soapstone if you are making a small sculpture that won't be easily damaged if you accidentally scratch or nudge it.
