Blast Furnace – Official Minecraft Wiki

Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail. Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace. Fuel is also used at double the rate of regular furnaces, so the number of items smelted per fuel stays the same.
