“ | The main point of a furnace is to smelt things. Smelting requires fuel - usually coal or charcoal, and an object to be smelted. Pop those in the furnace and you'll see a progress bar for the smelting process which, when completed, yields a new object. Be careful which fuel you choose, because some are more efficient than others. | „ |
| — Duncan Geere[1] |
A furnace is a block used to smelt blocks and items and convert them into other blocks or items.

Obtaining[edit]
Furnaces can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing. A furnace will also drop when a minecart with furnace is broken.

Natural generation[edit]
Two furnaces can be found inside each blacksmith shop in villages, and one can be found inside each igloo.
Furnaces also generate in weaponsmith houses in plains villages, inside some houses in snowy tundra villages, in some desert village houses, in taiga and snowy taiga village houses.[upcoming: JE 1.14 & BE 1.10]
Furnaces can also be found inside snowy tundra village house chests.[upcoming: JE 1.14]
Crafting[edit]
| Ingredients | Crafting recipe |

| Cobblestone |
The lit furnace block cannot be obtained in Java Edition, even with commands. In Bedrock Edition however, the lit furnace block can be obtained by inventory editing. It will always stay lit, despite no items being inside of it.
Usage[edit]
Furnaces cannot be pushed by pistons.[Java and Legacy Console editions only]

- Tags common to all block entities see Template:Nbt inherit/blockentity/template
- CustomName: Optional. The name of this container in JSON text component, which will display in its GUI where the default name ordinarily is.
- 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
- : An item in the furnace, including the slot tag:
- 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.
- RecipeLocationN: N is the number of the recipe, starting at 0. The recipe name that has been used, used to calculate experience given to the player when taking out the resulting item.
- RecipeAmountN: N is the number of the recipe, starting at 0. How many times recipe N has been used, used to calculate experience given to the player when taking out the resulting item.
- RecipeUsedSize: How many recipes have been used, creates corresponding RecipeLocationN and RecipeAmountN tags, used to calculate experience given to the player when taking out the resulting item.

Trivia[edit]
- Furnaces function as multiple devices combined into one block: bloomeries and blast furnaces (for smelting ores), an oven (for baking and cooking), a charcoal pit (for the charring of wood) and a kiln (for baking of clay).
- Cats will often sit on top of active furnace
