Level Requirements:

  • Smithing Levels: The minimum Smithing level required to use the Blast Furnace effectively varies depending on the type of bar being smelted. However, specific tasks within the Blast Furnace can be performed with no Smithing level requirement, but to smelt bars, certain levels are needed:
    • Iron bars: Level 15 Smithing
    • Steel bars: Level 30 Smithing
    • Mithril bars: Level 50 Smithing
    • Adamant bars: Level 70 Smithing
    • Rune bars: Level 85 Smithing
    • Gold bars, notably for XP efficiency, require Level 40 Smithing and are highly recommended to be smelted with goldsmith gauntlets for additional experience.
  • Operating Cost: For all players, regardless of their Smithing level, there’s an operational cost to use the Blast Furnace:
    • Players under level 60 Smithing must pay 2,500 coins every 10 minutes to the Blast Furnace Foreman for access, whereas players at level 60 Smithing and above can use the furnace for free. However, an hourly fee is still deducted from the coffer to pay the NPC workers for operating the machinery.


For an efficient Blast Furnace operation, certain gear and items are highly recommended. These enhance the smelting process by either reducing resource requirements, increasing experience rates, or improving player stamina and movement speed.

Ice Gloves and Goldsmith Gauntlets:

  • Ice Gloves: Obtained by defeating the Ice Queen located in the White Wolf Mountain. Ice Gloves are essential for handling hot bars directly from the bar dispenser without waiting for them to cool down. This significantly speeds up the bar collection process.
  • Goldsmith Gauntlets: A reward from completing the “Family Crest” quest. When worn, these gauntlets significantly increase the Smithing experience gained from smelting gold bars. Specifically, they boost the experience from 22.5 to 56.2 XP per gold bar, making gold smelting at the Blast Furnace the fastest Smithing experience in the game.
