Furnace

Introduced in version 0.3, Furnaces are items that let you smelt Cobblestone, Iron Ore, Gold Ore, Clay, Netherrack, Wood, Sand and raw meat. When you tap a Furnace, there will be a small area on the left of the screen showing your inventory (however, only items that are able to be smelted or used as fuel will be shown), 2 slots; the one on the top for the item to be smelted and the one on the bottom for the fuel, and a slot on the right for the output. Coal, Wooden Planks, Sticks, Charcoal, Bows and Saplings are currently the only items that can be used as fuel for a Furnace. Most people use Coal or Charcoal as fuel because one piece of Coal/Charcoal can smelt 8 items.

Trivia

 * Before Chests were added in 0.5, players would use Furnaces as storage areas since there is usually an abundance of Cobblestone in a world and Furnaces are crafted from Cobblestone.
 * If a Furnace is smelting in a dark area or at night, it will light up until it is done smelting, and for a couple seconds after that.
 * In Update 0.7.0 you were unable to use Furnaces, however this has been fixed.
