Nether Brick

Nether Brick is an Item, that is made by smelting Netherrack - a naturally spawning block, that can only be found in the The Nether - in a furnace. On its own, Nether Bricks cannot be used, but when crafted in a 2x2 square, it can be made into a block of Nether Brick. Nether Brick blocks can also be crafted into Nether Brick Fences, Nether Brick Stairs, and Nether Brick Slabs. The only other way of obtaining nether bricks is by finding a Nether Fortress, where Nether Bricks, Nether Brick Fences, and Nether Brick Stairs are all found naturally.
