A blast furnace is a block that smelts ores and metal items twice as quickly as a furnace, but cannot smelt anything else. It also serves as an armorer's job site block.

Obtaining

Breaking

A blast furnace can be picked up using any pickaxe. If mined without a pickaxe, it does not drop itself.

Blast furnaces drop their contents when broken.

Smelting

Blast furnaces are similar to furnaces, but can smelt only raw metal, ore blocks, ancient debris and tools/armor made of iron, gold, chainmail, or copper. Blast furnaces serve as the counterpart to smokers, which are used mainly to cook food faster. Smelting equipment yields one iron, gold or copper 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 using the output. Like normal furnaces, a hopper can be used to feed items into or collect items from a blast furnace.

Profession

If a blast furnace has not been claimed by a villager, any nearby unemployed villager has a chance to change their profession to armorer and claim the blast furnace as their job site block.

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 CustomName tag using the /data command.‌^{[Java Edition only]}

Lock

In Java Edition, a blast furnace can be "locked" by setting its lock tag using the /data command. If a blast furnace's lock tag is not blank, the blast furnace cannot be opened unless the player is holding an item with the same name as the lock 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 /data merge block 0 64 0 {lock:{components:{"custom_name":"Blast Furnace Key"}}}.
