Netherrack is a rock-like block found in the Nether.
- Times are for unenchanted tools as wielded by players with no status effects, measured in seconds. For more information, see Breaking § Speed.
In Bedrock Edition, netherrack generates as part of nether portals spawned floating.
When netherrack's top is lit on fire, the fire burns indefinitely.
