Calculate ore requirements and fuel efficiency for smelting ingots. Compare fuel options and optimize your furnace usage.
Coal is the most efficient (8 ores per unit). Use wood only in emergencies as it's very inefficient (1 ore per unit).
Base smelting time varies by ingot tier: Copper (10s), Iron (12s), up to Mithril (30s). Higher tier furnaces reduce these times.
Yes! With an upgraded furnace, you can smelt different ore types in parallel, each using its own fuel allocation.
