This article is about the furnace. For smelting processes and recipes, see Smelting.

	“	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

A furnace is a block used to smelt blocks and items and convert them into other blocks or items.

Obtaining

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.
