Obtaining[]

Natural generation

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.

One furnace generates in every igloo.

Breaking

A furnace can be mined using any pickaxe. A furnace will also drop all of its contents when broken, including XP from smelting items that were extracted by hoppers.

In Java Edition, a furnace mined without a pickaxe drops nothing. In Bedrock Edition, a furnace drops itself when mined by hand or with any tool.

1. Times are for unenchanted tools as wielded by players with no status effects, measured in seconds. For more information, see .

Chest loot

Crafting

The lit furnace can be obtained in Java Edition only with commands such as , 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.

Tiny fuel generator[]

Charcoal

Tiny Charcoal Generator

View at: Tutorials/Automatic smelting/Tiny Charcoal Generator

This design lets a furnace producing charcoal feed its product back into the furnace to fuel itself. It needs to be started off with one piece of charcoal (or for that matter, any fuel) in the chest. If more than 5-6 stacks of wood are available, another chest for input can be placed atop the upper hopper. Note that this design uses a comparator, which requires access to nether quartz.

The chest will not start receiving charcoal until both the furnace and the hopper feeding it fuel (level 2) are full. However, the hopper can be «stuffed» with four non-fuel items in its last four slots, as long as you leave the first slot open for fuel. Then the chest will start getting charcoal after two stacks of charcoal are produced, which will require 2-1⁄₄ stacks of wood.

See the following video for an example of how to make this:

Block data

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

See also: Block entity format

• Block entity data
  • Tags common to all block entities
  •  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.
  •  CustomName: Optional. The name of this container in JSON text component, which appears in its GUI where the default name ordinarily appears.
  •  Items: List of items in this 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
  •  Lock: Optional. When not blank, prevents the container from being opened unless the opener is holding an item whose name matches this string.
  •  RecipesUsed

     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.

    : 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.

Usage[]

Furnaces cannot be pushed by pistons in Java Edition.

Smelting

Main article: Smelting

Interface for the Furnace.

The main purpose of a furnace is smelting. Its interface can be opened by pressing the use item button on it. A fuel source (up to one stack of fuel items) is placed in the lower slot, and the items (up to one stack) to be smelted are placed in the upper slot. A furnace smelts items at a speed of one item every 10 seconds, or six items per minute.

The number of items that a fuel source can smelt depends on the type of fuel. As soon as smelting begins, the fuel slot is decremented immediately and that unit of fuel begins burning. The fuel continues burning until it is consumed, regardless of whether the upper slot has any items remaining to smelt. For example, a piece of coal burns for 80 seconds and can smelt eight items, but if only one item is smelted (or if the item is pulled out before smelting is complete), the coal still continues burning for the full 80 seconds, wasting seven items worth of smelting. After it burns out, no additional fuel is decremented from the fuel slot if the upper slot is empty. If the fuel slot is empty and the burning fuel is consumed before an item completes smelting, the smelting stops, the smelted item is unchanged, and smelting must be restarted with new fuel.

Crafting ingredient

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 tag using the command‌[Java Edition only].

Lock

In Java Edition, a furnace can be «locked» by setting its tag using the command. If a furnace’s tag is not blank, the furnace cannot be opened unless the player is holding an item with the same name as the 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 .

Automatic item Sorting furnace[]

Compact Item Sorting Furnace: Minecraft Redstone Tutorial Video

This fully-automatic build allows for seamless integration into an existing item sorting system, and runs automatically in the background as a predetermined item is collected before reaching its final storage location.

Items collected by the will be smelted by an internal furnace, collected by a set of hoppers, and transported back to the main hopper line with a dropper item elevator to be transported to a chest or storage system. This design will require the occasional addition of coal or fuel, when its corresponding chest runs low, to keep the furnace running.

The following items can be smelted with this automatic furnace design:

• Cobblestone
• Sand
• Iron ore
• Gold ore
• Netherrack
• Wet sponges
• Clay

Semi-automatic furnace[]

Semi-Automatic Smelter.I is Input (smeltables)F is fuelO is output.

This semi-automatic design uses hoppers, and is not too difficult to build and is inexpensive.

You will need 3 chests, 3 hoppers, and 1 furnace. The raw ingredients for this would be 8 cobblestone, 15 iron ingots, and 12 logs of wood (48 planks).

Build instructions

See below for a step-by-step guide on how to make this semi-automatic furnace design. Sneak (hold down ⇧ Shift) to attach blocks to each block that has an inventory, such as attaching a hopper to a chest. Otherwise you will open the block instead of placing the block.

• Step 1: Place down a chest on the ground. (This will be the chest in which the smelted/cooked items will be put)
• Step 2: Attach a hopper to the chest.
• Step 3: Place the furnace on top of the hopper.
• Step 4: Place one hopper on the top and 1 hopper on the side (left, right, front, or back) of the furnace. (The top one will insert the items into the furnace, which get smelted / cooked; The hopper on any side-face inputs burnable fuels into the furnace)
• Step 5: Place a chest on top of each hopper attached to the furnace.

Variations: You may choose to add switches to control the hoppers. Switching off the bottom hopper stops it from taking items out, allowing you to collect the experience from smelting them. Switching off the top hopper allows you to fill the top chest with various items, then eventually smelt them all in one go, reducing the fuel waste normally incurred by smelting partial stacks. The fuel hopper on the side never needs to be switched off.

Multiplayer: On servers that have chest and furnace protections, you may have to unlock these before the hoppers are able to interact with them.

Making two furnaces increases the rate of production much faster. Have a chest on top for the item to be smelted, and at the back, put a fuel chest.
