Quick answer: Furnace I is tied to Bronze Melting, while Furnace II is tied to Iron Forge. Build them from the Yard building desk, then make sure the Yard fuel system has stock before queuing smelting.

What is confirmed

  • Furnace I handles early bronze and glass-related production.
  • Furnace II adds iron and advanced engineering outputs.
  • Fuel is consumed by recipes and is managed separately from the furnace placement cost.
  • Research the required metallurgy node.
  • Open the Yard building desk and place the correct furnace.
  • Finish construction with the listed tool and mastery.
  • Add fuel through the Yard fuel storage, then test one smelting job.

What not to assume

Do not use Furnace 2 instructions from Graveyard Keeper 1. Station names may look familiar, but the sequel has different research and work-area relationships.
