Stone Bricks

Stone Brick is a new block type that was implemented in the 1.8 Beta update. Stone Bricks are one of the materials that are used in the Strongholds.

Stone brick the player crafts appears to have a very small chance of having the skin change to Cracked Stone Brick or Mossy Stone Brick when harvested. It's unknown if this is a glitch or intentional. The same phenomenon also happens with harvested Stone Brick Stairs.

Crafting
Stone Bricks can be crafted by placing 4 Stone blocks in a square.
