Nether Brick

Nether Brick is an Item made by smelting Netherrack - a naturally spawning block, that can only be found in the The Nether - in a furnace. On its own, Nether Brick items cannot be used on there own, but when put together in a Crafting Table, can be made into Nether Brick (Block)s. 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 brick blocks is by finding a Nether Fortress, where Nether Bricks, Nether Brick Fences, and Nether Brick Stairs are all found naturally.
