Blast Furnace

Blast furnaces are blocks used to smelt ores.

Natural generation
Blast furnaces can generate in all village variant armorer houses.

Smelting
Blast furnaces are used to smelt mineral blocks twice as fast as a regular furnace. 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. Like normal furnaces, a hopper can be fed into a blast furnace and can also pick up items from it.

Light source
Lit blast furnaces emit a light level of 13 blocks, similar to normal furnaces.

Block entity
A blast furnace has a block entity associated with it that holds additional data about the block.
