Players need to forge when upgrading weapons in Old School RuneScape. Among the many forging techniques, using Blast Furnace is one of the best ways to consume it. Getting the most out of your Blast Furnace is vital to your weapon, make sure you have enough OSRS Items, and complete a few tasks first:
Start ‘The Giant Dwarf' quest to gain access to Keldagrim
You’ll need at least 60 smithing (with no boosts) or alternatively, pay 2,500 to the Blast Furnace foreman to smelt bars for 10 minutes
Every hour at the Blast Furnace will use 80,000 GP, so be prepared
Please avoid using the "paid" option on the blast foreman as it will negate the effect of the ring. To reduce your entry fee, it is recommended to get the Ring of Charos (a). However, you can get this ring in Finkenslin's Creature questline.
When using the popsicle dispenser, it helps to bring ice gloves to the blast furnace, as it will quickly cool them for you to pick up to save time.
How to Get to OSRS Blast Furnace
Before you start your journey to the blast furnace itself, it's worth noting that it's only available in the following worlds: 352, 355, 358, 386, and 387. Once you speak the Giant Dwarf and enter Keldar Green, you need to:
Head north and make your way across the bridge
Once you’ve crossed it, keep going south until you see the Blast Furnace icon on the map
Go inside the marked building, walk downstairs and you'll find the furnace itself
Once this is done, it will be much easier to go there in the future. You can use the Grand Exchange shortcut on the northwest wall, ride a minecart through the Iceberg Dwarf Mine, or use the minigamegroup finder to appear outside the building.
How to use OSRS Blast Furnace
It takes a little getting used to at first, but Blast's mini-game is a breeze. To use the furnace, follow these steps:
Deposit your ore onto the conveyor belt
Run down the ramp prepared with a bucket of water or ice gloves
Cooldown your bars and bank them
Speed is critical here, so be sure to wear weight loss gear when traversing the blast furnace. For smithing players under 60, you need an stamina potion and 25 ores, while paying a cost every 10 minutes. If you're having trouble doing a quest, go to RPGStash.com for help, where you can Buy OSRS Items or Gold to enhance your quest completion.
