Blast Furnace

Blast furnaces are blocks used to smelt ores and smeltable armor and tools.

Obtaining
Blast furnaces can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing.

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

Usage
Blast furnaces cannot be pushed by pistons.

Blasting
Blast furnaces are similar to furnaces but are used to smelt mineral blocks in particular. 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, twice as fast as a regular furnace. Fuel is also used at double the rate of regular furnaces, so that the amount of items cooked per fuel stays the same. The product can then be collected by pressing on the blast furnace. 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  tag using the  command.

Change profession
If a village has a blast furnace and there's no armorer villager, any nearby villager who hasn't chosen a workstation has a chance to change their profession to armorer.

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