  • It contains dangerous chemicals.
  • It’s prone to staining.

The natural stone contains no chemicals, is impermeable (and therefore stain-resistant) and can withstand heat without taking damage. However, soapstone’s softness makes it vulnerable to scratches. On the Mohs Hardness Scale, which ranks minerals from 1 to 10 based on hardness (with diamonds ranking 10 and talc at a 1), soapstone falls between a 1 and 5, meaning it is rather soft. This softness allows it to be used for other purposes besides countertops but also means it can be easily damaged. This would be considered a con to owning soapstone.
