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

Obtaining [ edit ]

Natural generation [ edit ]

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 [ edit ]

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

Custom name [ edit ]

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 [ edit ]

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"} .

Trivia [ edit ]

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.
