How to Make a Blast Furnace in Minecraft (Recipe and Uses)

To make a blast furnace in Minecraft, place 5 iron ingots, 1 furnace, and 3 smooth stone in a crafting table. Put three iron ingots across the top row, an iron ingot on each side of the furnace in the middle row, and three smooth stone across the bottom row. The result is one blast furnace.

What you need to make a blast furnace

The recipe is simple, but smooth stone takes an extra smelting step. You need:

• 5 iron ingots
• 1 furnace
• 3 smooth stone
• A crafting table

Mojang introduced the block with this same 5-iron, 1-furnace, 3-smooth-stone recipe. You can see the original recipe in the official Minecraft Snapshot 18w50a notes.

How to make a blast furnace in Minecraft

1. Make or collect a regular furnace

If you do not already have a furnace, craft one first using the standard furnace recipe. The furnace is not just a tool for preparing the other materials; it is also an ingredient in the final blast furnace recipe.

2. Make three smooth stone

Smooth stone is made in two smelting stages. First, smelt cobblestone in a regular furnace to make stone. Then put that stone back into the furnace and smelt it again to make smooth stone. Repeat until you have three blocks.

Any normal furnace fuel that works for those smelting operations can be used. You do not need a blast furnace for this step; in fact, the blast furnace is designed for ores and metals rather than general stone processing.

3. Arrange the blast furnace recipe

Open a crafting table and fill the 3×3 grid in this exact pattern:

• Top row: iron ingot, iron ingot, iron ingot
• Middle row: iron ingot, furnace, iron ingot
• Bottom row: smooth stone, smooth stone, smooth stone

Move the blast furnace from the result slot into your inventory.

4. Place the blast furnace and start smelting

Place the block in your base and open it just like a normal furnace. Put a compatible ore, raw metal, or smeltable metal item in the input slot and add fuel below it.

A blast furnace processes eligible materials twice as fast as a regular furnace. Fuel is consumed twice as quickly as well, so the fuel cost per smelted item is effectively the same. Mojang explains this behavior in its official Blast Furnace Block of the Week guide.

What can a blast furnace smelt?

Think of the blast furnace as a specialized metal furnace. It is useful for supported ores, raw metals, and smeltable metal equipment. It is not a universal faster furnace.

You cannot use it to cook food, and it is not the right block for general materials such as sand or stone. For food, use a smoker if you want the same kind of speed boost; Mojang describes the smoker as the food-focused counterpart to the blast furnace in its official smoker guide.

Useful tips

If you need a blast furnace but do not want to craft one, Mojang notes that blast furnaces can also generate in some village armorer buildings. For a permanent base, however, crafting one is usually straightforward once you have iron and smooth stone.

For large mining sessions, a blast furnace is especially useful because it cuts the processing time for compatible materials in half. If your goal is to process several different item types, keep a regular furnace nearby as well rather than replacing it entirely.
