Composed primarily of talc, soapstone is a very soft material sometimes used for countertops. Color options are limited as it only comes in varying shades of gray. Most slabs are smaller than 7 feet meaning a project is more likely to have seams. Because of its softness, it can easily be scratched. Over time, soapstone will darken. Even though it is soft, Soapstone is non-porous and resistant to staining. Unlike most natural stone countertops, soapstone should never be chemically sealed. Mineral Oil is used to give soapstone its rich finish.
