Soapstone
A soft, talc-rich stone that is heat-resistant, non-porous and easy to shape, prized for countertops and sinks.
What is Soapstone?
Soapstone, also called steatite, is a metamorphic rock rich in talc, which gives it a soft, soapy feel — hence the name. It is much softer than granite or quartzite and can be cut and shaped with standard woodworking-style tools. Dimensional soapstone used for countertops contains less talc and is harder than the pure carving-grade material.
Properties
Soapstone is non-porous and does not require sealing, it resists acids (so it will not etch from citrus or vinegar like marble), and it is highly heat-resistant, which is why it has long been used for wood stoves, hearth liners and fireplace surrounds. It is typically grey, blue-grey or greenish-grey when fresh, and it darkens and develops a patina with oiling and use; scratches can be sanded or oiled out.
Applications
Soapstone is used for kitchen countertops and islands (with the understanding it will patina and can scratch), carved sinks and basins, wood stoves and fireplace surrounds, decorative carvings and artifacts, and lab tops where chemical resistance matters. It offers a distinctive matte, rustic look different from polished granite or quartz.
