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
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.
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).
How to Use The Blast Furnace
To use Blast Furnace, place the item you want to smelt in the first slot (upper left). And the fuel item under the first slot.
Now, wait for the Blast Furnace to smelt the items.
If you want to know what items Blast Furnace can smelt, see the table below:
|The Items||The Result|
1x Iron Nugget
1x Golden Nugget
|Iron Ore(s)||Iron Ingot(s)|
|Gold Ore/Nether Gold Ore(s)||Gold Ingot(s)|
|Lapis Lazuli Ore(s)||Lapis Lazuli(s)|
|Redstone Ore(s)||Redstone Dust(s)|
|Nether Quartz Ore(s)||Nether Quartz(s)|
|Diamond Ore(s)||Diamond (s)|
|Ancient Debris||Netherite Scap(s)|
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.
Blast Furnace and Regular Furnace Comparison
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.
Here are the fuels (and their burning times) you can use for Blast Furnace and Regular Furnace (it measured in seconds):
|Fuel Items||Burning Time (using Regular Furnace)||Burning Time (using Blast Furnace)|
|Lava Bucket||1000 s||500 s|
|Coal Block||800 s||400 s|
|Dried Kelp Block||200 s||100 s|
|Blaze Rod||120 s||60 s|
|Coal/Charcoal||80 s||40 s|
|Any types of Boats||60 s||30 s|
|Scaffolding||20 s||10 s|
|Any types of Wood Planks (except Crimson and Warped Planks)|
|Any types of Logs (except Crimson and Warped Stems)|
|Any types of Stripped Logs (except Stripped Crimson and Warped Stems )|
|Any types of Stripped Woods (except Stripped Crimson and Stripped Warped Hyphae)|
|Any types of Woods (except Crimson and Warped Hyphae)|
|Any types of Wooden Stairs (except Crimson and Warped Stairs)|
|Any types of Wooden Pressure Plates (except Crimson and Warped Pressure Plates)|
|Any types of Wooden Fences (except Crimson and Warped Fences)|
|Any types of Fence Gates (except Crimson and Warped Fence Gates)|
|Any types of Wooden Trapdoors (except Crimson and Warped Trapdoors)|
|Any types of Signs (except Crimson and Warped Signs)|
|Any types of Wooden Doors (except Crimson and Warped Doors)|
|Any types of Wooden Slabs (except Crimson and Warped Slabs)||7.5 s||3. 75 s|
|Any types of Saplings (including Dead Bush)|
|Any types of Wools|
|Any types of Wooden Buttons (except Crimson and Warped Buttons)|
|Any Types of Carpets||3.35 s||1.67 s|
|Bamboo||2.5 s||1.25 s|
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.
