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

THE BLAST FURNACE

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
