Smelting is the process in which Ores are turned into Bars using a Furnace. This requires Oil for most ores or Charcoal for Titanium Bars, which can be obtained from burning Logs in the Foundry or from Castle Dungeon Loot Bags. Higher tier Furnaces allow more Bars to be placed in the Furnace for smelting, but will not increase the smelting rate. The Blue Furnace Orb can further enhance this by adding 50% more capacity to all Furnaces. The Furnace Potion can be used to increase the smelting rate by three times, and Bar Potions can give a 20% chance to smelt two bars at the cost of one ore, with the Small Bar Potion working on Bars up to Gold Bars and the Large Bar Potion working on Bars up to Promethium Bars.
