Key Takeaway

To make a Blast Furnace in Minecraft, you’ll need the following:

  • 5 Iron Ingots
  • 3 Smooth Stone
  • 1 Furnace

Blast Furnaces smelt ore twice as fast as regular Furnaces—but also consumes fuel twice as quickly. Furthermore, Blast Furnaces cannot cook food; they can only smelt ore and melt down metal goods, such as tools and pieces of armor.

If you’re tired of waiting around for ore to smelt, don’t just make another Furnace to split the load—there’s a better way! Crafting a Blast Furnace in Minecraft lets you speed up the resource refining process so you’ll have more time for adventuring and building.

    How to Make a Blast Furnace in Minecraft

    To make a Blast Furnace in Minecraft, you’ll need to gather three types of items:

    • 5 Iron Ingots
    • 3 Smooth Stone
    • 1 Furnace

    Once you have these components, combine them on a Crafting Table. Place the three Smooth Stone on the bottom row. Following this, insert the Furnace into the middle slot. Finally, fill the remaining five slots with your five Iron Ingots. This crafting recipe gives you one Blast Furnace.

    How to Get Iron Ingots

    You get Iron Ingots from smelting Raw Iron in a Furnace. Each piece of Raw Iron gives you one Iron Ingot. To get Raw Iron, you must mine Iron Ore with a Stone Pickaxe or better.

    Iron Ore is fairly common; in each chunk, three batches are generated:

    • The first batch attempts to spawn Iron Ore blobs between 1 and 13 (Java Edition) or 1 and 16 (Bedrock Edition) 90 times between levels 80 and 384, with 232 being the most common for Iron Ore.
    • Next, the second batch tries to spawn 90 Iron Ore blobs between 1 and 13 (Java Edition) or 1 and 16 (Bedrock Edition) between levels -24 and 56, with 16 usually having the most Iron Ore.
    • Then, the third and final batch of 10 Iron Ore blobs—1 to 5 blocks in size—attempts to spawn between levels -64 and 72 with no individual level standing out as having more Iron Ore than others.

    How to Get Smooth Stone

    You can make Smooth Stone from Cobblestone by smelting the latter in a Furnace multiple times. Firstly, smelt Cobblestone to get Stone. Afterward, smelt Stone to get Smooth Stone. Rinse and repeat until you have all the Smooth Stone you want.

    How to Get a Furnace

    To craft a Furnace, place eight Cobblestone in a ring on a Crafting Table. This recipe results in one Furnace. Additionally, you can find pre-made Furnaces in Villages—which you can take with no consequences.

    Finding a Blast Furnace Instead of Crafting It

    If you get lucky, you can stumble upon a pre-made Blast Furnace in a Village or a Trail Ruin. To gather it, you must mine a Blast Furnace with any Pickaxe. Using your fists or another tool results in the Blast Furnace breaking but not dropping itself.

    How to Use a Blast Furnace in Minecraft

    A Blast Furnace is meant to speed up the ore refining process. The main benefit of using a Blast Furnace in Minecraft is that it smelts ore twice as quickly as a regular Furnace. However, it consumes fuel twice as fast, so you don’t save on resource consumption. Furthermore, you cannot cook food in a Blast Furnace; it’s only for metallurgy.

    To use a Blast Furnace, place fuel in the bottom-left slot (Coal, Charcoal, etc.) and the raw metal you want to smelt in the top-left slot. After the white arrow fills up, ingots appear in the right slot. Take your smelted ingots out when you’re ready to use them.

    Smelting Raw Gold into Gold Ingots with a Blast Furnace.

    On top of refining raw metal into ingots, Blast Furnaces lets you melt down iron, gold, and chainmail armor pieces into nuggets. Each iron tool, or piece of iron or chainmail armor, melts down into one Iron Nugget apiece. Similarly, gold armor pieces and tools melt down into one Gold Nugget each.

    Why a Blast Furnace Is Better Than Two Furnaces

    While using two Furnaces results in smelting at the same speed as one Blast Furnace, doing so requires twice the amount of fuel. Using one Blast Furnace saves you from having to mine more Coal or convert Wood Blocks into Charcoal. The latter of which is not efficient at all since one Wood Block can be used to create four Wooden Planks or eight Sticks.

    Blast Furnaces as Job Site Blocks

    You can place a Blast Furnace near an unemployed Villager to turn them into an Armorer. Make sure the unemployed Villager stays close to the Blast Furnace until it transforms.

    If you’re upgrading your refining setup in your Minecraft world, don’t stop at merely making Blast Furnaces! Connect them to Hoppers, Levers, and Redstone Torches to automate the process. That way, you can spend more time building, exploring, and experimenting!
