Blast Furnace

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.

Breaking
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.

Natural generation
Blast furnaces can generate in any armorer house; these can be found in a village. They can also generate in trail ruins.

Usage
Blast furnaces can be pushed by pistons.

Smelting


Blast furnaces are similar to furnaces, but can smelt only raw ore, ore blocks and tools/armor made of iron, gold or chainmail. Blast furnaces serve as the counterpart to smokers, which are used mainly to cook food faster. Smelting equipment yields one iron or gold nugget from their respective materials. 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. The product can then be collected by the output. Like normal furnaces, a hopper can be used to feed items into a blast furnace and can also pick up items from it.

Changing profession
If a village has a blast furnace that has not been claimed by a villager, any nearby villager who has not chosen a job site block has a chance to change their profession to armorer.

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

Custom name
By default, the interface of a blast 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.

Lock
$$, a blast furnace can be "locked" by setting its  tag using the  command. If a blast furnace's  tag is not blank, the blast furnace cannot be opened unless the player is holding an item with the same name as the   tag's text. For example, to lock a blast furnace at (0,64,0) so that the blast furnace cannot be opened unless the player is holding an item named "Blast Furnace Key", use.

Note Blocks
Blast furnace can be placed under note blocks to produce "bass drum" sounds.
