Are you building a Stone Fireplace?

Why settle for traditional clay fire bricks when you can have the luxury of an all natural, all stone Fireplace!

Let Stonetrade turn your ordinary firebrick fireplace into a beautiful imported all stone fireplace.

Mariana Soapstone Firebrick:

A natural fireplace liner made of all stone

You’ve chosen the perfect mantel & surround – why not design an all stone fireplace using the dove gray beauty of soapstone instead of clay firebrick?

Soapstone’s special mineral properties make it ideal for lining stone 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 hearth efficiency.

But perhaps the best thing is the look: a soft gray firebrick with natural veining & texture. It is a real upgrade to ordinary clay firebrick.  And after all, what part of a fireplace hearth do you look at most: the firebox! Soapstone firebrick will make a beautiful back drop to your next fire.

Our soapstone firebrick 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 Firebrick 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 firebricks you would need for your project.

Mariana Soapstone™ Firebrick FAQ- For a beautiful stone fireplace

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.

Yes, our soapstone has been tested and meets ASTM C-1261 (Standard Specification for Firebox Brick for Residential Fireplaces).

Choose your layout & brick size

We have four sizes of bricks:

Standard:    9" × 4½" × 2½"
Split:             9" × 4½" × 1¼"
Strip:             9" × 2 ½" × 1¼"
Soap:             9" x 2 ½" x 2 ½"

Decide what brick face you want to show and how thick you want the soapstone to be (2 ½”, 4 ½”, or 1 ¼”).  For wood-burning fireplaces, we recommend a minimum soapstone thickness of 2½".  IsokernTM and gas fireplaces may be able to use 1¼" thickness: check with your fire inspector.
