Mariana Soapstone™ Firebrick FAQ
A metamorphic rock, primarily made of the mineral talc. It is not anything like limestone, marble, granite, slate or sandstone. It is reasonably soft and can be scratched with metal. True soapstone has special mineral properties that make it ideal for lining fireplaces.
Soapstone has a low thermal coefficient of expansion: it doesn’t expand and contract much when its heated and cooled, so its less likely to crack or spall than other natural stones. Plus, soapstone is extremely dense, so it absorbs and retain heats for long periods of time. Soapstone is non-porous & not chemically reactive, so it won’t stain or discolor like marble or limestone.
All varieties of true soapstone are gray, with some lighter and darker veining.. The stone varies somewhat in the amount of patterning and white veining.
Sealers are not necessary to protect the stone and will not last in a fireplace. Soapstone countertops are often oiled to make them black: this should not be done in a fireplace application.
