Where to Find Blast Furnace in Minecraft

Blast Furnace is a utility item in the Utility Blocks category of Minecraft, and this guide names the 2 places it turns up, the 2 routes that end with one in your hand, and the fastest of them. Short version: Blast Furnace sits in All Overworld biomes (crafting) and Villages (Armorer houses), and craft using 5 Iron Ingots, 1 Furnace, and 3 Smooth Stone. Difficulty for Blast Furnace: 2 of 5, which we call easy, since most players can secure it within their first in-game day with basic tools. You will not be hunting for Blast Furnace across biomes at all: a Crafting Table is the whole source, so read on for what goes into it, what each part costs you and the best moment to make one.

A blast furnace is a furnace, five iron ingots and three smooth stone. It smelts ore twice as fast as a normal furnace and nothing else at all, so the practical setup is one blast furnace next to one ordinary furnace: ore in the first, food and glass in the second.

A blast furnace needs a furnace, five iron and three smooth stone, and it smelts ore twice as fast while refusing everything else. That specialisation is the point: a row of blast furnaces on the ore line and ordinary furnaces on the food line stops the two jobs competing for space.
