Black Granite (GregTech 5)

Black Granite is an deep black type of stone added by GregTech. It spawns naturally in the overworld in form of huge boulders replacing vanilla Stone.

Black Granite is much harder than Stone and can be processed into different building blocks. Its variations are: Black Granite, Black Granite Cobblestone, Black Granite Bricks, Cracked Black Granite Bricks, Chiseled Black Granite and Smooth Black Granite.

Bricks, Chiseled and Smooth Black Granite stop mobs from spawning above them.
