Getting the most you can from your Blast Furnace is crucial to your weapons, however it does require a couple of tasks that must be accomplished before. Make sure you're well-stocked on GP since the following jobs will be expensive: Begin the quest 'The Giant Dwarf' for access to Keldagrim. It's recommended that you have at least 60smithing (with the exception of boosts) or, alternatively paying 2,500 to one of the Blast Furnace foreman to RS Gold smelt bars for 10 minutes. Every hour , the Blast Furnace will require the equivalent of 80,000 GP So be ready.

To cut down on the entrance cost we recommend that you get the Ring of Charos (a). Avoid using the 'pay' option with foreman at the Blast Furnace foreman because it could void the effect of the ring. You can gain this ring through The Creature of Fenkenstrain questline.

The addition of Ice Gloves in the Blast Furnace will be beneficial when you're using the bar dispenser, since it cools the bars in a short time for you to pick up. This can save you time, instead of needing buckets full of water every time to cool your bars (and it'll save inventory space too).

Before you begin you journey toward the Blast Furnace it's worth noting that it's only accessible within the worlds that are: 352, 355 3, 358, 386 and 387. Once you've spoken the Giant Dwarf, and then entered Keldagrim the next step is to: Head north and make your way across the bridge. After crossing it, continue to go south until you find that Blast Furnace icon on the map. In the designated building, walk downstairs and Buy RS Gold you'll discover the furnace.
