Netherrack
Netherrack is the soft red rock that fills the Nether — burns indefinitely once lit and yields easily to any pickaxe.
Description
Netherrack's most distinctive property is permanent fire: placing fire on top of a Netherrack block via flint and steel or a fire charge causes the flame to burn indefinitely without consuming Netherrack. Builders exploit this to create eternal campfires, decorative torches, or atmosphere-rich Nether-themed builds. Netherrack has very low blast resistance of 0.4, so it shatters immediately under explosions and should never be used as a protective wall. Smelting one Netherrack in a furnace yields one Nether Brick item — the raw material required to craft Nether Brick blocks and Nether Brick slabs. Netherrack is not renewable, making stockpiling worthwhile if players plan large-scale builds using Nether Brick.

How to use Netherrack in Minecraft
-
1
Find and collect Netherrack in the Nether
Netherrack generates throughout the Nether dimension in all biomes except areas dominated by Soul Sand Valley. Bring any pickaxe — even a wooden one works — because Netherrack has hardness 0.4 and breaks almost instantly. Netherrack drops itself without Silk Touch, so no enchantment is needed for bulk collection.

2
Create permanent fire for decoration or utility
Place a Netherrack block anywhere in your build, then ignite the top face with flint and steel or a fire charge. The fire burns indefinitely without consuming Netherrack. This technique is ideal for fireplaces, Nether portals ambiance, throne rooms, or any eternal flame effect. Only water, explosions, or player action can extinguish the flame.

3
Smelt Netherrack into Nether Brick items
Insert Netherrack into the top slot of a furnace and any fuel below. Each Netherrack smelts into one Nether Brick item (not the block). Collect four Nether Brick items to craft one Nether Brick block in a 2×2 crafting grid. This is the primary way to obtain Nether Brick for fortress-style construction.

4
Use Netherrack as fast-breaking filler in Nether builds
Because Netherrack breaks in under a second with any pickaxe, large Nether excavation projects move quickly. Clear vast underground areas or sculpt biome-authentic caves using Netherrack as the primary material. Its blood-red texture blends naturally with other Nether blocks like magma blocks and soul sand.

Avoid Netherrack in explosion-prone areas
Netherrack has a blast resistance of only 0.4 — far lower than stone (6.0) or obsidian (1200). Ghast fireballs and creeper explosions destroy Netherrack instantly. If using Netherrack in builds near Nether mobs, layer it behind blast-resistant blocks or keep fire decorations away from key structures.
Stack multiple Netherrack blocks vertically and light the top one for a tall eternal fire column — a dramatic effect for Nether-themed bases or portals.

Frequently asked questions
Does fire on Netherrack burn forever?
Yes. Fire placed on top of Netherrack using flint and steel or a fire charge burns permanently without consuming Netherrack. Only water, explosions, or direct player removal (right-click to extinguish) will stop the fire.
What tool is needed to mine Netherrack?
Any pickaxe works — wooden, stone, iron, gold, diamond, or netherite. Netherrack has hardness 0.4 and breaks faster than stone with any pickaxe. Netherrack drops itself without Silk Touch.
What does smelting Netherrack produce?
Smelting one Netherrack in a furnace produces one Nether Brick item. Four Nether Brick items can then be crafted into one Nether Brick block in a 2×2 crafting grid.
Where does Netherrack generate in Minecraft?
Netherrack generates throughout the Nether dimension, forming floors, walls, and ceilings across almost all biomes. It is partially replaced by Crimson Nylium and Warped Nylium in their respective biomes since the 1.16 Nether Update.
Can Netherrack be used to build structures?
Yes, Netherrack can be used for Nether-themed atmospheric builds. However, Netherrack has a blast resistance of only 0.4 — extremely low — so it is not suitable for walls or structures that need to survive explosions. Use it for interior decoration or fire features rather than defensive construction.
Is Netherrack renewable?
No. Netherrack is a naturally generated block found only in the Nether and cannot be crafted, traded, or otherwise reproduced. Once all Netherrack in an area is mined, it does not regenerate.
