How to Make a Blast Furnace in Minecraft
Blast Furnace TipsThe Blast Furnace is one of the most impactful quality-of-life upgrades in a Minecraft base — the double-speed ore smelting alone justifies the 5 Iron Ingot crafting cost within the first mining session it processes. Players who discover it early dramatically reduce the dead time spent waiting for furnaces and can process large ore hauls in half the time, keeping the gameplay momentum from mining sessions flowing directly into gear upgrades without a long wait. The Armorer trade route adds long-term value as a source of Enchanted Diamond armour, and the Smooth Stone requirement ties it naturally into any stone-processing setup. Combine the Blast Furnace with a Smoker (double-speed food cooking) to cover all your smelting needs at maximum efficiency — regular furnaces become backup units for the occasional material that doesn’t fit either specialised station. This trio of furnace, Blast Furnace, and Smoker is the foundation of any well-organised Minecraft base’s resource processing area.FAQ
⚡ Quick Answer
How to Craft and Use a Blast FurnaceTo make a Blast Furnace place 5 Iron Ingots across the top row and middle-left and middle-right slots, 1 Furnace in the middle-centre, and 3 Smooth Stone across the bottom row. The Blast Furnace smelts ores and metal items at twice the speed of a regular furnace using the same fuel — but only works on ores, raw metals, and metal armour/tools. It’s also the Armorer villager’s job site block.
1
Craft Smooth Stone — smelt Stone twice. The Blast Furnace requires 3 Smooth Stone blocks. To get Smooth Stone: smelt Cobblestone in a regular furnace → produces Stone → smelt Stone again → produces Smooth Stone. Two smelting passes from Cobblestone. Smooth Stone cannot be crafted directly — it requires the double-smelt process. You’ll need at least 3 Smooth Stone blocks for the recipe. This is the most involved material in the Blast Furnace recipe and the one players most commonly forget when first crafting it.
2
Craft a regular Furnace. You need 1 Furnace as an ingredient. Craft it with 8 Cobblestone filling all slots of a crafting table except the centre. You almost certainly already have a Furnace by the time you’re crafting a Blast Furnace — if so, you can use your existing one as the ingredient and replace it with a new regular Furnace crafted immediately after. Alternatively, you can find Furnaces in Villages and use one from there. The Furnace ingredient is consumed in the recipe — it becomes part of the Blast Furnace.
3
Craft the Blast Furnace at a crafting table. Open a crafting table and arrange: Top row — Iron Ingot, Iron Ingot, Iron Ingot. Middle row — Iron Ingot, Furnace, Iron Ingot. Bottom row — Smooth Stone, Smooth Stone, Smooth Stone. This produces 1 Blast Furnace. Place it anywhere in your base like a regular furnace. The Blast Furnace looks similar to a regular furnace but with an industrial iron frame aesthetic — it glows orange-red when active and has the same right-click interface as a regular furnace with input, fuel, and output slots.

What the Blast Furnace smelts — ores and metal items only. The Blast Furnace processes a limited category of items at double speed: Raw ores (Raw Iron, Raw Gold, Raw Copper → their Ingots), Ore blocks (Iron Ore, Gold Ore, Copper Ore, Ancient Debris → Netherite Scrap), Metal armour and tools (Iron Sword, Diamond Pickaxe — smelting these gives 1 Nugget and removes the item; useful for clearing inventory of old gear). It cannot smelt food (use a Smoker for that), Sand into Glass, Clay into Terracotta, or any non-metal material. The speed advantage: regular furnace takes 10 seconds per item; Blast Furnace takes 5 seconds — exactly half. Same fuel efficiency per item.
5
XP from Blast Furnace smelting — same total, faster delivery. Smelting ores in a Blast Furnace produces the same total XP per item as a regular furnace — it’s just delivered twice as fast. This means large-scale ore smelting in a Blast Furnace generates the same XP as a regular furnace over the same number of items, but in half the time. For XP farming specifically, this makes Blast Furnaces more efficient per unit of time when processing stockpiled raw ore. Collect the XP by opening the Blast Furnace and taking items from the output slot — XP orbs pop out when you retrieve smelted items.
6
Armorer Villager — the Blast Furnace job site trade route. Placing a Blast Furnace near an unemployed Villager assigns them the Armorer profession. Armorer Villagers trade Iron Ingots, Coal, and Diamonds for Emeralds, and sell armour pieces — including Enchanted Diamond armour at Master level — for Emeralds. The Master Armorer Diamond Chestplate trade is one of the best sources of Enchanted Diamond armour without relying on enchanting table RNG. Combine with the Grindstone to disenchant armour with bad enchantments and the Smithing Table to upgrade Diamond armour to Netherite for the complete end-game gear workflow.

Always use a Blast Furnace for ore smelting — regular furnaces are only for everything else: the only reason to smelt ores in a regular furnace is if you don’t have a Blast Furnace yet. Once crafted, the Blast Furnace should handle all ore, raw metal, and metal tool/armour smelting. Keep regular furnaces for food, Sand, Clay, Cobblestone→Stone, and other non-metal smelting. Dividing tasks between furnace types is the correct efficient base smelting setup.

Smelt old Iron and Gold armour/tools for Nuggets — clean your inventory fast: right-clicking the Blast Furnace with old Iron Swords, Iron Armour, or Gold items smelts them into Iron or Gold Nuggets (9 Nuggets = 1 Ingot). This converts junk gear from mob drops, dungeon loot, and old equipment into usable raw materials instead of discarding them. A single Blast Furnace session after a major dungeon run converts all the Iron junk into useful Ingots.

Use a Hopper below the Blast Furnace to auto-collect output: place a Hopper directly under the Blast Furnace and connect it to a Chest — smelted items automatically flow into the Chest without manual collection. Add a second Hopper on the side feeding raw ore into the input slot for a fully automated smelting line. This is the standard base smelting array setup used by most experienced Minecraft builders. The Redstone builds guide covers more advanced automated smelting designs.

Ancient Debris only smelts in regular furnaces AND Blast Furnaces: Ancient Debris (used to make Netherite) smelts into Netherite Scraps in both regular and Blast Furnaces. Use the Blast Furnace for faster Netherite Scrap production — every second counts when Ancient Debris is so rare that you may have gathered a small stack over a long mining session. The double-speed processing means fewer furnace fuel items consumed waiting for Scraps.

Build a bank of 4+ Blast Furnaces for mass ore processing: when you return from a long mining session with 200+ Raw Iron, a single Blast Furnace still takes time even at double speed. A row of 4 Blast Furnaces processing in parallel quarters the total time. Place them side by side with Hoppers underneath feeding into a shared Chest — load all four simultaneously for maximum throughput. Four Blast Furnaces processing together turns a 30-minute smelting job into 7 minutes.
What does a Blast Furnace do in Minecraft?
A Blast Furnace smelts ores, raw metals, and metal armour/tools at twice the speed of a regular furnace using the same amount of fuel per item. It only works on metal-type items — it cannot smelt food, Sand, Clay, or other non-metal materials. It’s also the Armorer villager’s job site block.
How do you make a Blast Furnace in Minecraft?
Place 5 Iron Ingots (top row + middle-left and middle-right), 1 Furnace (middle-centre), and 3 Smooth Stone (bottom row) in a crafting table. Smooth Stone is made by smelting Cobblestone into Stone, then smelting Stone again. The regular Furnace ingredient is consumed in the recipe.
What can you smelt in a Blast Furnace in Minecraft?
Blast Furnaces smelt raw ores (Iron, Gold, Copper, Ancient Debris), ore blocks (Iron Ore, Gold Ore, Copper Ore, Nether Gold Ore), and metal armour and tools (Iron, Gold, Chainmail items — they produce Nuggets). They cannot smelt food, Sand, Clay, Wood, or any non-metal material. Use a Smoker for food and a regular furnace for everything else.
Is the Blast Furnace faster than a regular furnace in Minecraft?
Yes — the Blast Furnace smelts at exactly twice the speed of a regular furnace. A regular furnace takes 10 seconds per item; the Blast Furnace takes 5 seconds. Fuel efficiency is the same — each fuel item smelts the same number of items in either furnace. The only advantage is speed, not fuel savings.
