Smelting

Smelting is the process of obtaining refined goods from raw materials by heating them in a furnace, blast furnace or smoker. When items are smelted in either type of furnace, some experience is dropped. Like crafting, smelting uses recipes to determine what item is produced.

The furnace interface contains three item slots: the upper left slot for the item that needs to be smelted, the lower left slot for fuel, and the right slot where output items accumulate and can be retrieved by the player. Flames above the fuel slot act as a gauge showing the amount of fuel left of the current fuel item. An arrow in the middle shows the progress of smelting the current item.

The furnace takes 10 seconds (200 in-game ticks) to smelt an item. It begins to smelt if both input item and fuel are placed into the corresponding slots, and there is space in the output slot.
