The Stone Furnace is a crafting station that processes stones, ores, and other minerals for different types of resources. These resources can be used to construct objects and equipment.

Each item takes a certain amount of time to process, provided that the stone furnace has fuel to operate. The Stone Furnace uses Wood for fuel, with 20 Wood being the maximum capacity for fuel. Fuel can last up to 20 hours, in which the crafting station needs to be refueled again. Upon running out of fuel, the Stone Furnace will halt all production. Up to 10 of the same item can be crafted at one time and will display the total time to completely process all of the materials. Only one type of item can be crafted at any time, however, multiple Stone Furnaces can be created.
