What netherrack is
Netherrack is the reddish, fleshy-looking stone that makes up most of the Nether. If you’ve ever stepped through a portal and seen the ground stretching out in every direction in shades of red and brown, that’s netherrack. It’s the basic block of Nether terrain, the way stone is for the overworld.
The block is soft enough to mine with a wooden pickaxe and common enough that you’ll have stacks of it within minutes of arriving. It also has one trick no other common block has: light it on fire and it burns forever. That single property is the reason most players bring some back to the overworld.
Where to find netherrack
Netherrack is the default block of the Nether dimension. It generates from the top of the Nether (Y=127) down to bedrock, with caves, lava lakes, and ore veins cutting through it. Every Nether biome uses netherrack as the base block: the Nether Wastes, Crimson Forest, Warped Forest, Soul Sand Valley, and Basalt Deltas all sit on netherrack underneath their surface features.
Outside of the Nether, netherrack doesn’t generate naturally. If you want any in the overworld or End, you have to mine it in the Nether and carry it back. The block isn’t damaged by lava, so transporting it is safe.
How to mine netherrack
Mining netherrack needs any pickaxe. A wooden pickaxe works just as well as a netherite one for getting the drop. Higher tiers only matter for speed: netherrack is one of the fastest blocks in the game to break, so even a wooden pickaxe clears it in under half a second.
Without a pickaxe, the block still breaks if you keep punching, but it doesn’t drop anything. The same rule applies as with stone: wrong tool, no item.
Each block drops one netherrack. There’s no fortune bonus and no XP. The block doesn’t need silk touch because it drops itself by default.
Bulk-mining tips:
- Bring a pickaxe with Efficiency. It’s overkill for the block, but it lets you clear tunnels at a sprint.
- Watch for lava. Netherrack is the most common block in the Nether, but it has lava lakes and pockets at every Y level. Always have a fire resistance potion and a way out.
- Ghasts can knock you around while you mine. Cover your back, especially in open Nether Wastes.
The eternal flame
Netherrack has one of the most useful properties of any block in the game: once lit on fire, it keeps burning forever unless something puts it out. The fire on top of a netherrack block won’t go out from time alone, which is what makes the block worth carrying home.
To light it, use flint and steel, a fire charge, or a fire aspect weapon. The flame stays put. It doesn’t spread to non-flammable blocks on its own. A player or mob walking through it takes fire damage, just like any other fire.
Common uses for the trick:
- Fireplaces. Place a netherrack block in a stone or brick recess and light the top. The fire stays for atmosphere without burning your house down.
- Lit decorative tiles. A line of lit netherrack along a wall reads like a row of small flames.
- Old-style portal frames. Older versions of the game used netherrack inside obsidian portal frames. It’s no longer required, but some builders still place it as a visual marker.
- Choke-point mob damage. A netherrack tile with fire on top will damage mobs that walk over it. Not a full mob trap design, but useful for narrowing entrances.
One thing to know: the fire on netherrack is still fire. If you place flammable blocks (wood, wool, leaves) next to it, those blocks will ignite and burn normally. The netherrack itself never burns up, but anything next to it can.
What puts a netherrack fire out: water placed adjacent, a player or mob breaking the fire by punching it, and rain if the block is in the overworld. In the Nether and End, there’s no rain, so the fire stays.
Smelting and crafting
Put netherrack in a furnace and you get nether brick (the item). Four nether brick items in a 2×2 crafting pattern make one nether bricks block. Nether bricks blocks are the input for nether brick stairs, slabs, fences, walls, and the red nether brick variant when combined with nether wart.
The full chain looks like this:
- Mine netherrack in the Nether.
- Smelt it in a furnace to get nether brick (the item).
- Combine 4 nether bricks in a crafting grid to make 1 nether bricks block.
- Use nether bricks blocks as the input for any nether brick recipe.
If you’re planning a big nether brick build, the limiting step is the smelting. A blast furnace doesn’t smelt netherrack because blast furnaces only handle ore and ore-like items. You’re stuck with regular furnaces. Set up a row of furnaces with auto-feed hoppers and let them run while you do something else.
Fuel-wise, netherrack itself can’t be used as fuel. The block looks like it should burn, but mechanically it doesn’t count as a fuel item. Use coal, charcoal, or anything else that already works in your furnace.
Mob spawning and behavior
Hostile mobs in the Nether ignore the usual light-level rule. They spawn on netherrack regardless of how bright it is. That’s why building a fully lit Nether base still leaves you exposed: lighting doesn’t stop spawns the way it does in the overworld.
What does stop spawns on netherrack:
- Replacing the block with anything else. Mobs only spawn on netherrack and a handful of other Nether-native blocks. Lay a path of cobblestone or smooth stone and nothing spawns on it.
- Half-slabs and stairs in the top half of the block. Mobs need a full block face to spawn on, so a half-slab placed at the top of a netherrack column prevents spawning on that column.
- Carpets, snow layers, and other non-collision blocks placed on top. Same logic.
If you’re carving out a base in the Nether and you want it mob-free, replace the floor. Don’t try to light your way out of the problem.
Tips and common mistakes
A few things players learn the slow way:
- Don’t strip-mine netherrack hoping for ores. Most Nether ores (quartz, gold, ancient debris) generate inside netherrack veins, but the block itself doesn’t have hidden drops. Mining netherrack for the sake of mining netherrack only gets you netherrack.
- Don’t store flammable blocks near a netherrack fireplace. A chest of wood next to a lit netherrack tile is one stray spark from gone.
- Don’t build long netherrack bridges over lava with wooden details next to them. The netherrack is fine. Anything wooden along it isn’t.
- Use netherrack as a path block in builds that want a warm, baked-clay look. It pairs well with red sandstone, granite, and brick.
Java vs Bedrock differences
For netherrack itself, the two versions behave the same: same drops, same mining, same fire mechanics. The few differences worth knowing:
- Mob spawning weights on netherrack vary slightly between editions, but the practical effect is the same: hostile mobs will spawn at any light level.
- Some texture packs and shader interactions render netherrack slightly differently on Bedrock vs Java, but the underlying block is identical.
- Commands that target netherrack use the ID
minecraft:netherrackin both editions.
Frequently asked questions
Can you craft netherrack?
No. There’s no crafting recipe for netherrack. The only way to get it is to mine it in the Nether, or use commands in creative mode.
Does netherrack really burn forever?
Once lit on fire with flint and steel or another ignition source, yes. The fire on top of netherrack stays until water, rain, or a player breaks it. The netherrack block itself doesn’t burn up, so you can leave a fireplace running for as long as your world exists.
What pickaxe do you need to mine netherrack?
A wooden pickaxe is the minimum. Any pickaxe tier from wood up through netherite drops the block. Without a pickaxe, the block still breaks but doesn’t drop anything.
Can netherrack be used as fuel?
No. Despite its appearance, netherrack isn’t a valid furnace fuel. Use coal, charcoal, or another fuel item to smelt it.
Does rain put out netherrack fire?
In the overworld, yes. Rain extinguishes fire on top of netherrack the same way it extinguishes any other fire. In the Nether, there’s no rain, so the fire stays lit.
Can mobs spawn on netherrack?
Yes, and they spawn at any light level. This is one of the main differences between the Nether and the overworld. Torches and lanterns won’t stop spawns on netherrack.
What’s the fastest way to get a lot of netherrack?
Find any open Nether biome (Nether Wastes is the easiest), bring an Efficiency pickaxe, and dig in a straight line. A single minute of clearing will give you several stacks. Carry fire resistance if you’re not confident around lava.
One last thing
If you’re new to building in the Nether or planning your first big nether brick castle, mine your netherrack in the upper layers near your portal exit. Top-of-Nether mining keeps you away from lava lakes and lets you set up a small base safely before going deeper. Build a small fireplace on the way out as a marker for the route home.
