Can you cover a brick fireplace with granite?
Brick is a common material used when building a fireplace because of its heat resistance, durability and attractiveness. Installing granite tile over the bricks provides you with a way to update the fireplace to fit the new decor while still using a fire resistant material.

What is a granite stone?

Is Limestone good for fire pit?
6. The center of the fire pit can be covered with several inches of Blue Granite, Mason Sand or Lava Rock. Never use limestone as excess heat can cause limestone to explode.
How do you cut granite?
