A furnace is a storage block used for smelting of blocks and items, converting them into other blocks or items.

Obtaining

Natural generation

One furnace generates in every igloo.

Furnaces can be found in plains, desert, and some savanna village weaponsmiths. Furnaces also generate in some houses in snowy tundra villages, and in one of the taiga/snowy taiga‌^{[BE only]} village houses.

Breaking

Furnaces can be mined using any pickaxe. If mined without a pickaxe, it drops nothing. Furnaces also drop all of their contents.

Entity loot

In Java Edition, breaking a minecart with furnace drops both the furnace and the Minecart.

Chest loot

Crafting

Ingredients	Crafting recipe
Any Cobblestone or Blackstone

The lit furnace can be obtained in Java Edition only with commands such as /give @s minecraft:furnace{BlockStateTag:{lit:"true"}}, although it does not appear lit in the inventory. In Bedrock Edition, the lit furnace block can be obtained only by inventory editing. It always stays lit, despite containing no items.

Usage

Furnaces cannot be pushed by pistons in Java Edition.

Smelting

Main article: Smelting

Smelting Recipe

The main purpose of furnaces is to allow for smelting. Its interface can be opened by pressing the use item button on it.

Light source

Furnaces emit a light level of 13 when active, as well as smoke and flame particles.

Crafting ingredient

Name	Ingredients	Crafting recipe	Description
Blast Furnace	Iron Ingot + Furnace + Smooth Stone
Minecart with Furnace	Furnace + Minecart		‌[Java Edition only]
Smoker	Any Log or Any Stripped Log or Any Wood or Any Stripped Wood + Furnace

Custom name

By default, the GUI of a furnace is labeled "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 furnace can be "locked" by setting its Lock tag using the /data command. If a furnace's Lock tag is not blank, the 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 furnace at (0,64,0) so that the furnace cannot be opened unless the player is holding an item named "Furnace Key", use /data merge block 0 64 0 {Lock:"Furnace Key"}.

Block entity

See also: Block entity format

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

• Block entity data
  • Tags common to all block entities see Template:Nbt inherit/blockentity/template
  •  CustomName: Optional. The name of this container in JSON text component, which appears in its GUI where the default name ordinarily appears.
  •  Lock: Optional. When not blank, prevents the container from being opened unless the opener is holding an item whose name matches this string.
  •  Items: List of items in the container.
    • : An item in the 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
  •  BurnTime: Number of ticks left before the current fuel runs out.
  •  CookTime: 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 BurnTime reaches 0.
  •  CookTimeTotal: Number of ticks It takes for the item to be smelted.
  •  RecipesUsed: Which recipes 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.
    •  recipe ID: How many times this specific recipe has been used. The recipe ID is the namespaced ID of the smelting recipe, as used in the /recipe command.

Trivia

• Furnaces function as multiple real-world devices combined into one block: bloomeries and blast furnaces (for smelting ores), ovens (for baking and cooking), charcoal pits (for the charring of wood) and kilns (for baking of clay).
• Tamed cats often sit on top of lit furnaces.
• A lava bucket is the most effective fuel to use, smelting 100 items.
  • However, a block of coal is the best renewable fuel, smelting 80 items.
