Blast Furnace – Minecraft Wiki
A blast furnace is a block that smelts ores, raw metals and metal armor and tools twice as quickly as a furnace but cannot smelt anything else. It also serves as an armorer's job site block. A blast furnace can be picked up using any pickaxe. If mined without a pickaxe, it does not drop. Blast furnaces drop their contents when broken. Blast furnaces can …
