Buy Mariana Soapstone Fire Brick : A fireplace liner of natural stone.
You’ve chosen the perfect mantel & surround – why not design your fireplace using the dove gray beauty of soapstone?
Soapstone’s special mineral properties make it ideal for lining fireplaces. Soapstone is a refractory material: it can withstand high temperatures without cracking.
It is also extremely dense and has a high thermal capacity, so it holds heat and radiates it slowly for hours, improving fireplace efficiency.
But perhaps the best thing is the look: a soft gray fire brick with natural veining & texture. It is a real upgrade to ordinary brick. And after all, what part of a fireplace to look at most: the firebox! Soapstone fire brick will make a beautiful back drop to your next fire.
Our soapstone fire brick is suitable for use with both gas and wood burning fireplaces, and is often used to line the interiors of Isokern™ or FireRock™ fireplaces.
We stock our Mariana Soapstone Fire brick in four different sizes, and we ship nationwide. Send us an email, or use the inquiry form at the bottom of this page to get prices, installation tips, layout guides, and a calculator that will show you how many soapstone fire bricks you would need for your project.
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.
