Frequently Asked Questions

How much wood does it take to smelt metal ore in Rust?expand_more

In a standard Furnace it is about 1.67 wood per metal ore, so 1,000 ore needs roughly 1,670 wood. A Large Furnace is far more efficient at ~0.33 wood per ore, and the Electric Furnace uses no wood at all — it runs on power.

How long does it take to smelt 1000 metal ore?expand_more

About 55 minutes in a single Furnace (3.33 seconds per ore), or around 11 minutes in a Large Furnace. Running several furnaces at once splits the time — two furnaces halve it.

Is the Large Furnace worth it?expand_more

Yes, by a wide margin. It smelts far faster and uses less wood per ore than a standard Furnace. The catch is it costs more to build and can not be picked up, but for serious farming it is the standard.

What does the Electric Furnace do differently?expand_more

It smelts using electricity instead of wood — no fuel to feed and no charcoal produced. It is slower per ore than a Large Furnace and needs a power setup, but it is hands-off once wired.
