Smelting Recipe

Blast furnaces are used to smelt mineral blocks twice as fast as a regular furnace resulting in half the experience.‌^{[Java Edition only]} When a smelting item and a fuel is placed into the blast furnace the block state will change to lit and the item will smelt. The product can then be collected. Its interface can be opened by pressing use on it.

Like normal furnaces, a hopper can be fed into a blast furnace and can also pick up items from it.

Light source

Blast furnaces emit a light level of 13 when active, similar to normal furnaces.

Custom name

By default, the GUI of a furnace is labeled "Blast Furnace", but this name can be customized by naming it in an anvil before placing it, or by changing the CustomName tag using the /data command.
