How to Use the Furnace in Minecraft

By Jesse Stay, Thomas Stay, Jacob Cordeiro

You use the furnace in Minecraft, an important part of the Stone Age, to craft many more items. Many players mine for cobblestone and make a furnace on their first or second day because of its importance. Placing a furnace on a surface and right-clicking it opens a menu with three slots: fuel, input, and output.


The fuel slot can take coal (eight uses per lump), wooden objects (three uses per 2 planks), and items such as blaze rods or lava buckets. It also takes a variety of other flammable items.

A more effective way to use wood as fuel is to place a wood log in the top and place wooden planks in the bottom of the furnace, creating charcoal. Charcoal then burns in the bottom of the furnace longer than the wood used to make the charcoal.

Using a furnace grants experience orbs, and the items described in the table become available.
