Netherrack
Netherrack is the soft red rock that fills the Nether — burns indefinitely once lit and yields easily to any pickaxe.

Description
Netherrack makes up the bulk of the Nether dimension — its rolling red landscapes, cliff faces, and ceilings are almost entirely composed of this material. Visually it reads as a coarse blood-red stone with darker veins running across the surface, a colour palette no Overworld block matches outside of dyed terracotta.
A wooden pickaxe is the minimum required tool, and the block breaks faster than ordinary stone — useful given how much of it stands between a player and any Nether resource. The defining property is permanent flammability: a flame placed on top, by flint and steel or fire charge, will burn forever without consuming the block. This is why Nether floors covered in fire are so common: builders set the bait once and it never goes out. Mining returns the block as-is without Silk Touch. Smelting in a furnace produces nether bricks, the foundation of fortress-style builds.
