Nether Bricks

Nether Brick is a type of block added in 1.0.0; they first appeared in the first 1.9 Pre-Release. They are used to form generated structures in The Nether, making up a majority of Nether fortresses, forming their walls and supporting pillars. Currently, the player can not craft Nether Brick. However, Nether Brick can be crafted into Nether Brick Stairs and Nether Brick Fences. Nether Bricks take approximately one second to mine with a stone pickaxe, which is a little shorter than the time required to mine normal stone. Nether Brick does not burn continuously, unlike Netherrack. It appears similar to the Brick(block) but textured with different textures. When walking on it, it makes the same step sound as Stone. So far, the only uses for the Nether Brick is to make stairs, fences, and as a pleasing decoration.

Trivia

 * Despite common misconception, Nether Bricks cannot be made out of Netherrack.
 * The only place where you can find Nether Bricks currently is in a Nether Fortress
 * In comparison, the Nether brick and Bricks seem similar, but are different by rectangles that make them up placed in different locations on the brick.
