Blast Furnace Overview

Inside the Armorer’s house.

Blast Furnace is one of the 13 job site blocks that Villagers use to work. A Villager who works with Blast Furnace is called Armorer. You can always find a Blast Furnace inside Armorer’s house.


If there is an unemployed/jobless Villager standing near a Blast Furnace, It becomes an Armorer.

Unlike regular Furnace, you can use Blast Furnace for smelting Ore Blocks, Iron, Gold, and Chainmail items only. And it is 2× faster than the regular Furnace.

Blast Furnace doesn’t require more fuel even it’s faster than the Regular Furnace. 

For example, to smelt 64 Iron Ores, you need 8 Coals as fuel when you use the Regular Furnace. 

But when you use the Blast Furnace, you also need 8 Coals as the fuel, not more than that. The thing is, Blast Furnace is just faster, but only for smelting ore-related items.

I hope this post helps you understand Blast Furnace in Minecraft. Also, check out the Smoker, the Blast Furnace’s twin. Thank you for reading the article.

  1. Fan of this website

    You said:”And it is 2x faster than the regular Furnace. ” but forgot to say that it is just for the items that the furnace can actually smelt XD. But I really like this website.

    • Dex

      I think I’ve made it clear enough. I have already written what kind of items that Blast Furnace can smelt before the “And it is 2x faster than the regular Furnace.” sentence.

      If you think, there is another thing I should fix, just tell me. Btw, thanks for commenting and became a fan of my website ^_^/

      Your suggestion is really important to me.
