If you need a Minecraft blast furnace for all your smelting needs, you’ve come to the right place. Creating a blast furnace in Minecraft is the first step towards being able to smelt your old gear into iron ingots, which you can use to craft other items, such as a Minecraft anvil or Minecraft grindstone.

You can find blast furnaces in Minecraft villages in armourer houses. If there isn’t an armourer villager already using a blast furnace as their job site block, then any villager can change their profession to armourer. Blast furnaces finish smelting at double the speed of a regular furnace and can be used to smelt ores, iron armour, and tools.

To create a blast furnace, you’ll first need to craft a normal furnace, which you can do by using eight pieces of Cobblestone in the crafting grid. Now you’ve got your furnace, here is the rest of the Minecraft blast furnace recipe and what you can do with it when it’s all fired up and ready to go.

How to use a blast furnace in Minecraft

You can use a Minecraft blast furnace for smelting ore blocks, tools, and armour – as well as gold or chainmail. To use the blast furnace, you’ll need to place the item and fuel onto the blast furnace to change the state to ‘lit’. The item on the blast furnace will be smelted twice as fast as a regular furnace, but fuel used on the blast furnace will also be used at double the rate. You can collect the smelted item from the block by selecting ‘use item’.

Here are some other facts about the blast furnace:

  • Any villager in a village without a dedicated armourer can become an armourer when standing nearby the blast furnace.
  • You can’t smelt food. Use a normal furnace or a campfire instead.
  • You will get less experience collecting items from a blast furnace than from a regular furnace.
  • You can’t push blast furnaces with pistons.
  • They have similar resistances to explosions and emit a light level similar to normal furnaces when active.
  • You can use a blast furnace with hoppers.

Using a Minecraft blast furnace on a block of ore will melt it down to iron ingots quickly and efficiently, so you can use it for your other crafting needs, whether using a Minecraft enchantment table, repairing your gear with a Minecraft anvil, or creating a Minecraft banner for your shield.
