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.

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.

Legend

• incorrect tool, drops nothing
• correct tool, drops nothing or something other than the block itself
• correct tool, drops the block itself
• italicized can be instant mined

Natural generation

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

Usage

Blast furnaces can be pushed by pistons.‌

Smelting

The GUI for the blast furnace, same as the ordinary furnace's.

Blast furnaces are similar to furnaces, but can smelt only raw metal, 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 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.‌

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" sounds.

Block data

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

Java Edition:

• [NBT Compound / JSON Object] Block entity data
  • Tags common to all block entities see Template:Nbt inherit/blockentity/template[show]
  • [Short] lit_time_remaining: Number of ticks left before the current fuel runs out.
  • [Short] cooking_time_spent: Number of ticks the item has been smelting for. The item finishes smelting when this value reaches 200 (10 seconds). Is reset to 0 if lit_time_remaining reaches 0.
  • [Short] cooking_total_time: Number of ticks it takes for the item to be smelted.
  • [Short] lit_total_time: Represent the total time the furnace should be lit.
  • Tags common to all objects that can be renamed see Template:Nbt inherit/nameable/template[show]
  • [NBT List / JSON Array] Items: List of items in this container.
    • [NBT Compound / JSON Object]: An item in the blast furnace, including the slot tag:
      Slot 0: The item(s) being smelted.
      Slot 1: The item(s) to use as the next fuel source.
      Slot 2: The item(s) in the result slot.
      • Tags common to all items see Template:Nbt inherit/item/template[show]
  • Tags common to all containers that can be locked see Template:Nbt inherit/lockable/template[show]
  • [NBT Compound / JSON Object] RecipesUsed: Recipes that have been used since the last time a recipe result item was manually removed from the GUI. Used to calculate experience given to the player when taking out the resulting item. Is not preserved when removed.
    • [Int] recipe ID: How many times this specific recipe has been used. The recipe ID is the identifier of the smelting recipe, as a resource location, as used in the /recipe command.
