The Furnace is a utility block used to smelt ores or to cook raw food and ingredients to make recipes. It is required to smelt ingots which are used to make a variety of tools and as such the furnace is a vital piece of equipment.
Furnaces can be crafted by placing four pieces of basalt adjacent to one another while in the inventory or workbench crafting interface.
As of update 2.0, furnaces can smelt 3 materials instead of 2 and now have easy smelt.
In-game description (Furnace): "Use furnaces to smelt a variety of items into other forms."
In-game description (Lit Furnace): "Use furnaces to smelt a variety of items into other forms. This furnace is fueled and hot!"
Uses[]
The Furnace Interface
The furnace is quite a useful block, as you can smelt specific blocks into other blocks (i.e. Clay into Bricks), cook and prepare food, melt ores into gems and ingots, and more.
Any block that is placed directly next to any of the six sides of a lit furnace (not diagonal) will be powered.

Trivia[]
Before Update 1.8 introduced basalt mountains on the surface, the furnace was moderately hard to get without the use of a shop. The player had to mine down almost 400 blocks just to mine the basalt required to make a furnace.
The bar representing fuel time is a flattened lava texture and the progress bar is a flattened dark green block texture.
