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. 

How to Craft a Blast Furnace

To craft a Blast Furnace, you need 5 Iron Ingots, 1 Furnace, and 3 Smooth Stones (to get Smooth Stones, you need to smelt Stones).

The Fuel Level.

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

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 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.
