The Furnace is one of the first essential structures you need in Forager. It lets you smelt ores into ingots, create coal from stone, and process other materials needed for progression. You cannot advance through the game without building one.
How to Build the Furnace
Open the game menu by pressing Escape (PC), then select the “Build” tab at the top of the screen.
On the right side, you’ll see four building categories: Industrial, Farming, Economic, and Magic. The Furnace is located in the Industrial section.
Furnace Cost
Building a Furnace requires 10 Stone. You can gather stone by mining the gray rocks scattered around your starting island.
Placing the Furnace
Select the Furnace from the build menu and click anywhere on your island to place it. A good strategy is placing it against the edge of your island or near a wall so resources don’t spawn behind it where you can’t see them.
What You Can Smelt
The Furnace processes raw materials into refined versions:
- Stone → Coal (essential for smelting ores)
- Iron Ore + Coal → Iron Ingot
- Gold Ore + Coal → Gold Ingot
- Sand → Glass
- Wood → Coal (alternative coal source)
Next Steps
After building your Furnace, you’ll also want to build a Forge (also in the Industrial section). The Forge uses ingots to craft coins, keys, tools, and other metal items. Together, the Furnace and Forge form the core of your early-game crafting setup.
