Black Granite hearths are suitable for gas fireplaces and electric fireplaces, and are not suitable for solid fuel applications (such as burning coal and logs). In order to make a black granite hearth suitable for solid fuel, the hearth needs to be cut into sections (usually 3 sections) and filled in the back with cement. This will allow a purpose built vent for the hot air to escape and prevent the hearth from cracking. There is no such requirement needed if you will be using a gas or electric fire.
