Furnace

The Furnace is a smelter used to turn Copper Ore, Tin Ore, and Iron Ore into their respective bars. It is part of the game’s basic metalworking progression and serves as one of the first essential crafting stations for turning raw ore into usable materials.

In practice, the Furnace is used whenever you need to process early- and mid-tier ore into bars for crafting. Its role is straightforward: place the appropriate ore into the Furnace and collect the matching bar output. Because it only handles Copper, Tin, and Iron Ore, it is limited to the standard metal resources shown in its description.
