— In-game Description
The Refining Forge is a refining structure for refining raw materials, which are important for making metal items and advanced technology. The Refining Forge can smelt Metal into Metal Ingots or refine Oil and Hide into Gasoline, with fuel (Wood, Thatch, Sparkpowder, or Angler Gel) without having to learn any other engrams.
A calculator is available here to help you automate the calculations of all forge types.
