How To Craft A Blast Furnace In Minecraft? Tutorial 2025

If you’re serious about efficiency in your Minecraft world, then it’s time to take a closer look at one of the game’s most useful blocks: the blast furnace Minecraft players often overlook. Whether you’re smelting tons of ores or trying to optimize your base, this powerful tool can significantly speed up your progress.

What is a Blast Furnace in Minecraft?

The blast furnace Minecraft introduced in the 1.14 Village & Pillage update is a specialized version of the regular furnace. Its primary function is to smelt ores, metal tools, and armor at twice the speed of a normal furnace. While it may seem limited because it can’t cook food or smelt non-metal items, the blast furnace is a game-changer for players who do a lot of mining and crafting.

Its interface is similar to a regular furnace, but the outcome is speed, at a cost. While it works faster, it also consumes fuel twice as quickly. This trade-off makes it perfect for players with a steady fuel supply and a large stock of ores.

How to Craft a Blast Furnace in Minecraft

To create the blast furnace Minecraft players love, you need the following materials:

• 1 Furnace
• 5 Iron Ingots
• 3 Smooth Stone

Crafting steps:

1. Open your crafting table.
2. Place the furnace in the center slot.
3. Put three iron ingots across the top row.
4. Place the remaining two iron ingots on the sides of the middle row.
5. Fill the bottom row with smooth stone.

Once crafted, you can place the blast furnace wherever it’s most convenient in your base—ideally near your mining storage or blacksmithing area.

Where to Find a Blast Furnace

If you don’t want to craft one, the blast furnace Minecraft generates naturally in village armorer houses. This makes it an easy way to get one early in the game. Just find a village, explore the houses, and look for the stone brick structure containing this block. You can break it and take it with you using a pickaxe.

Keep in mind: if you remove a blast furnace from a village, any armorer linked to it will lose their profession unless they find another one.

How to Use the Blast Furnace

Using the blast furnace Minecraft gives you is simple:

1. Open the blast furnace interface by right-clicking it.
2. Place a smeltable item like iron ore in the top slot.
3. Add a fuel source (coal, charcoal, lava bucket) in the bottom slot.
4. Wait a few seconds, and your item will be smelted!

Items smelt twice as fast compared to a regular furnace, but they also burn through fuel twice as quickly. Always have a steady supply of fuel if you plan to use the blast furnace frequently.

What Can You Smelt?

The blast furnace Minecraft supports can only smelt certain items:

• Ores: Iron, gold, copper, etc.
• Metal tools & weapons: Iron and gold gear.
• Armor: Iron and gold armor, including chainmail.

You cannot smelt:

• Food
• Sand
• Clay
• Cobblestone or other blocks not related to metal

Use regular furnaces or smokers for those items.

Why Use a Blast Furnace?

Here’s why the blast furnace Minecraft offers is essential:

• Speed: Twice as fast smelting helps process large quantities of ore.
• Convenience: Excellent for mining bases and metal-focused builds.
• Job Site Block: It turns unemployed villagers into armorers, allowing you to trade for enchanted gear.
• Redstone Potential: Can be used in automated smelting systems with hoppers and chests.

It’s especially helpful during mid-game when you’re building infrastructure and need iron and gold quickly.

Turn Villagers into Armorers

Another big advantage is that the blast furnace Minecraft recognizes as a job site block. When you place it next to an unemployed villager, it turns them into an armorer. This is incredibly useful if you want to trade for armor or tools without crafting them yourself.

Leveling up an armorer through trades can eventually grant you access to enchanted diamond armor, making the blast furnace a tool not only for smelting, but also for gearing up quickly.

Efficiency Tips

To maximize your use of the blast furnace Minecraft provides, consider these tips:

• Use lava buckets as fuel for large smelting sessions (they last longer than coal).
• Automate with hoppers feeding items in and out of the furnace.
• Have multiple blast furnaces if you’re processing large amounts of ore.
• Keep it near your mine or storage so you can smelt materials as soon as you collect them.

Mistakes to Avoid

Here are a few common errors players make when using the blast furnace:

• Trying to smelt food or glass – remember, the blast furnace Minecraft uses is only for metal-related items.
• Wasting fuel by smelting just one item at a time. Always smelt in batches to be fuel-efficient.
• Neglecting villager trades – turning villagers into armorers with a blast furnace opens up powerful trading opportunities.

Final Thoughts

The blast furnace Minecraft players can use is more than just a fancy upgrade—it’s a specialized, high-speed smelter that saves time and helps you progress faster. While it has a narrow function, it excels at what it does best: smelting ores and metal gear rapidly. It’s also one of the few utility blocks that plays a role in the villager job system, making it useful beyond simple crafting.

Whether you’re building a mega base, mining for hours, or preparing for battle, adding a blast furnace to your setup is a smart and efficient move.
