Nether Bricks

Nether Brick is a type of block that will be added to The Nether; they exist only in the current 1.9 Pre-Release. They are used to form generated structures in The Nether, making up a majority of the Nether Ruins, 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 do not stay lit on fire, unlike Netherrack. When lava is above the Nether Brick there is a chance that the lava will drip through.
