Nether Bricks

Nether bricks are blocks used to form nether fortresses in the Nether.

Red Nether bricks, cracked Nether bricks and chiseled Nether bricks are decorative variants that do not naturally generate.

Breaking
Nether bricks can be mined using any pickaxe. If mined without a pickaxe, they drop nothing.

Natural generation
Nether bricks form the walls and supporting pillars of all Nether fortresses.

Usage
Nether bricks are non-flammable and immune to ghast fireballs, making it a suitable shelter material for the Nether.

If a Nether bricks block is inside the whole bounding box of a Nether fortress (not just inside the individual parts), nether fortress mobs (such as blazes and wither skeletons) can spawn on it if other normal conditions are met. It is not known if this is an exclusive property of the block.

Note Blocks
All types of Nether bricks can be placed under note blocks to produce "bass drum" sound.
