Old School RuneScape has a variety of smithing techniques that you can learn about, but The Blast Furnace one of the best methods to use up the coal RS Gold Buy. Runescape continues to flourish all these years later, as Old School Runescape is no an exception to the game's ongoing success. OSRS gives players that unique nostalgia that only Jagex can deliver, with an original Runescape experience preserved perfectly to enjoy.
Making the most out from the Blast Furnace is vital for your armaments but it does require a few tasks which must be accomplished before. Be sure to stock up with GP since the following jobs won't be cheap: Start The Giant Dwarf quest for access to Keldagrim.
It's recommended that you have at least 60 smithing (with the exception of boosts) or alternatively, pay 2,500 dollars to the Blast Furnace foreman to smelt bars for 10 minutes. Every hour at the Blast Furnace will require an average of 80,000 GP which is why you should be prepared.
To reduce your entrance fee I would suggest acquiring the Ring of Charos (a). Avoid using the option to pay with foreman at the Blast Furnace foreman as it will void the effects of the rings. You can gain this ring by completing The Creature of Fenkenstrain questline.
Bring Ice Gloves to the Blast Furnace will help when making use of the bar dispenser because they will cool them quickly for you to use rs07 gold. This will reduce time instead of having buckets full of water in order to cool your bars (and it'll help you save inventory space too).
