Crafting station[]

Furnace can be used to smelt copper and bronze bars, as well as process dinas, stone, and clay.

Furnace uses Dregs, Wood or Power Stones as fuel. Crafting requires 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. In addition the Water Tank must supply all crafting stations with Water while running.

Furnace can be used to craft the following materials:
