Blast Furnace Minecraft: Recipe and Uses
The Blast Furnace recipe is 5 Iron Ingots, 1 Furnace and 3 Smooth Stone placed across three rows. Use it to smelt ore twice as fast for half the fuel cost, plus get it as a job site for Armorer villagers.
The short answer
A Blast Furnace is a specialised smelter for ore and metal. Craft it with 5 Iron Ingots, 1 Furnace and 3 Smooth Stone, and it will process ore blocks twice as fast as a Furnace while using half the fuel per item.
Blast Furnace crafting recipe
Crafting layout (3x3 grid)
| Slot position | Ingredient |
|---|---|
| Top-left | Iron Ingot |
| Top-centre | Iron Ingot |
| Top-right | Iron Ingot |
| Middle-left | Iron Ingot |
| Middle-centre | Furnace |
| Middle-right | Iron Ingot |
| Bottom-left | Smooth Stone |
| Bottom-centre | Smooth Stone |
| Bottom-right | Smooth Stone |
Craft it in four steps
- Make a Furnace. Surround the centre of your Crafting Table with 8 Cobblestone.
- Make Smooth Stone. Smelt Cobblestone into Stone, then smelt that Stone a second time. You need 3 blocks.
- Smelt Iron Ore. Mine Iron Ore with a Stone Pickaxe or better, then smelt it into Iron Ingots. You need 5.
- Assemble. Place the Furnace in the centre, ring it with the 5 Iron Ingots, and line the bottom row with 3 Smooth Stone.
Total material cost: 5 Iron Ingots, 3 Smooth Stone and 1 Furnace, which itself costs 8 Cobblestone.
What a Blast Furnace can and cannot smelt
Accepted
- All ore blocks: Iron Ore, Gold Ore, Copper Ore, Deepslate variants.
- Raw metals: Raw Iron, Raw Gold, Raw Copper.
- Iron and Gold tools, armour and horse armour, recycled into nuggets.
Rejected
- Cobblestone and Stone type building blocks, except plain Stone which polishes into Smooth Stone.
- All food, including Raw Beef, Kelp and Potatoes.
- Sand into Glass, Clay into Terracotta, Netherrack into Nether Brick.
Remember it this way: a Blast Furnace is for metal, a Smoker is for food, and a regular Furnace handles everything else.
How to use a Blast Furnace efficiently
Single furnace basics
- Place the Blast Furnace and right-click to open it.
- Put ore or raw metal in the top slot.
- Put fuel such as Coal, Charcoal or a Lava Bucket in the bottom slot.
- Take ingots from the right slot to claim the XP.
Because each fuel unit handles twice as many items as a regular Furnace, one Coal smelts 16 items instead of 8.
Scale up with an automatic smelter array
- Place a row of Blast Furnaces with a Hopper feeding their top faces from a minecart or chest line.
- Add a second hopper line along the backs feeding fuel into every furnace.
- Run a collection hopper underneath leading to a chest.
- Leave one output item in each furnace you want to collect XP from later — this pauses XP until you take that item out, letting you bank experience and cash it in when enchanting.
Why hoppers matter
Hoppers let furnaces run while you mine elsewhere, and they prevent over-filling the input slot. Feeding from the top keeps the output slot free for manual XP collection.
Blast Furnace vs Furnace vs Smoker
| Feature | Furnace | Blast Furnace | Smoker |
|---|---|---|---|
| Ore smelting | Yes, standard speed | Yes, double speed | No |
| Food cooking | Yes, standard speed | No | Yes, double speed |
| Smooth Stone polishing | Yes | Yes, double speed | No |
| Recipe cost | 8 Cobblestone | 3 Smooth Stone, 5 Iron, 1 Furnace | 1 Furnace, 4 logs or stems |
| Villager job site | No | Armorer | Butcher |
Extra uses worth knowing
- Armorer workstation. Place an unemployed villager next to a Blast Furnace to turn them into an Armorer, then trade emeralds for Iron Armour, chainmail and Diamond chestplates.
- Village loot. Blast Furnaces generate inside Armorer houses in most village types, giving you a free furnace during early raids.
- Redstone compatibility. Comparators can read a Blast Furnace for fuel level, which is how smart smelter designs auto-shutoff when fuel runs low.
Troubleshooting
The UI opens but nothing smelts. Your input is not metal. Move it to a regular Furnace or Smoker.
I built it and got a Smoker instead. Smokers use logs instead of Smooth Stone, so check that the bottom row is Smooth Stone and not planks.
No recipe appears. Smooth Stone is required, and ordinary Stone will not work. Smelt Stone one more time to convert it.
My XP is missing. Experience is only granted when you remove output items manually; a hopper taking items out grants none. Leave one nugget behind to hold XP for later.

Frequently Asked Questions
What is the Blast Furnace recipe in Minecraft?
Place 3 Smooth Stone across the bottom row, 5 Iron Ingots along the middle row and left and right slots of the top row, and 1 Furnace in the centre of the Crafting Table. In other words, a ring of Iron Ingots around a Furnace with a Smooth Stone base.
Why use a Blast Furnace instead of a Furnace?
A Blast Furnace smelts ore and raw metals twice as fast and uses half the fuel per item. The trade-off is that it cannot smelt food, Cobblestone or Smooth Stone type building materials — it accepts only ores, raw metals, iron and gold tools and armour.
Why will my Blast Furnace not accept Coal?
Coal placed in the top slot is input material, not fuel. Put fuel such as Coal or Charcoal in the bottom slot. If you placed an item the Blast Furnace rejects, like Cobblestone, it will simply not process.
Do Blast Furnaces give XP when you take items out?
Yes. Removing smelted output grants experience, exactly like a regular Furnace, which is why automatic smelter setups commonly include a hopper chain that pauses output to bank XP.
