How To Make a Blast Furnace in Minecraft [3 Easy Steps]

Key Takeaways
  • A blast furnace in Minecraft is a specialized tool for smelting ores, raw metals, and metal tools/armor. It works twice as fast as a regular furnace but can't be used for cooking like a furnace or smoker.
  • Players can find blast furnaces in villagers' armorer houses or trail runes in forest biomes, and they can also craft one using a furnace, 5 iron ingots, and 3 smooth stones.
  • While a furnace and smoker can cook food and process various items, a blast furnace is solely focused on smelting ores and metals at double the speed of a regular furnace.

A furnace is one of the most essential blocks in Minecraft. Without a furnace, you cannot obtain materials normally obtained by smelting, meaning that you won’t be able to craft more complex objects neither upgrade your gear. And while a furnace is good, a blast furnace is better.

Today, we’ll be discussing what is a blast furnace, how you can obtain it, and how does it compare to a normal furnace and a smoker.

    2. Now, we’ll need cobblestone. Cobblestone is pretty common on the surface but the most surefire way to get some is by mining underground. We’ll need a total of 8 blocks.
