Blast Furnace – Minecraft Wiki

A blast furnace is a block that smelts ores, raw metals, iron and gold armor and tools, similar to a furnace, but at twice the rate. It also serves as an armorer's job site block. A blast furnace can be picked up by any pickaxe. If mined without a pickaxe, it does not drop anything. Blast furnaces drop their contents when broken. Blast furnaces can generate in any armorer house; these can be ...
