A blast furnace is a block that smelts ores, raw metals‌^{[upcoming: JE 1.17]}, iron and gold armor and tools, similar to a furnace, but at twice the rate. It also serves as an armorer's job site block.

Obtaining

Breaking

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

Smelting

Main article: Smelting

Blast furnaces are similar to furnaces, but can smelt only 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 using the output. 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 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]}

Change profession

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

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:"Blast Furnace Key"}.

Note Blocks

Blast furnace can be placed under note blocks to produce "bass drum" sound.
