In today’s post, you will learn how to craft and use Blast Furnace in Minecraft. You can use the table of contents above to navigate quickly.

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 2x faster than the regular Furnace.

The fuel you use for Blast Furnace has a burning time. It determines how long a fuel item will last while smelting some item(s). The fuel level pictured as the “fire level” you see on the Blast Furnace’s menu.

You can see the list of fuel and their burning times in the comparison section below. It used as a comparison between a Blast Furnace and a Regular Furnace.

If you want to know the comparison side by side on how fast between the Blast Furnace and Regular Furnace, see the video below.


As you can see, the Blast Furnace is 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 the 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.
