The Stone Furnace is a crafting station that processes copper and tin ores as well as sand, stone, and wood. As with all crafting stations, only one type of item can be produced at a time.

Items require the furnace to be fueled for a certain amount of time. Upon running out of fuel, the production is halted mid process until more fuel is added. The Stone Furnace uses wood as fuel to produce items. It has a maximum fuel capacity of 20 Wood with each piece providing 1 hour of fuel time. 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.
