OSRS Blast Furnace Guide: All Ores

Blast Furnace is one of the classic OSRS minigames that has always been in the game and has always been famous for being the fastest place to get Smithing XP by smelting Gold Ores, which only requires 40 Smithing. Because of this, many players take the fast track of leveling up to 1-40 Smithing in an anvil and then quickly come to Blast Furnace.

How to get the Blast furnace

The Blast Furnace is a popular smithing minigame located in Keldagrim. To acquire access to Keldagrim, players must begin the Giant Dwarf quest by speaking with the Dwarven Boatman, who can be found east of Relleka. There are several routes to get to the blast furnace:

Fastest way to get there

•   The quickest way to travel to the blast furnace is via this teleport, which takes you right up to the entrance. However, you must have made at least one prior trip to the blast furnace before using it.

•   Mine cart from the Dwarven Mines

The Dwarven mines can be found under the Ice Mountain or in the Grand Exchange, but you need to travel to the Dwarven mine at least once to unlock this option.

•   Fairy ring DKS

This takes you close to the entrance of the Keldagrim, as shown above.

•   Running there from Relleka or Seer’s village

With construction level 30, you can ask any House Agent to change the location of your house to Relleka, which makes it a teleporter super close to the entrance of Keldagrim. If you don't have that level of construction, you can teleport to Camelot and then run to the entrance of Keldagrim.

The Official Worlds for Blast Furnace

There are up to 15 Blast Furnace worlds in OSRS, being the most popular 358; using these worlds is highly recommended. You can easily teleport to Seer’s village using runes or the Camelot teleport, then follow the path.

How the Blast Furnace Works

The Blast Furnace is located in Keldagrim and allows you to smelt bars using only half the coal normally required, which is why the XP and GP spent rates are so strong. The blast furnace requires a 72,000 coins fee per hour.

Once inside, you'll interact mainly with three key components:

• Bank Chest 

Playing the blast furnace is quite easy. There is a bank in the blast furnace that can be used to obtain the items you need. The bank will be your best friend in this minigame, used to withdraw ores and to store bars when you finish each trip.

• Conveyor Belt 

You would need to place ores on the conveyor belt. After a few seconds, the corresponding bars will be in the bar dispenser. Check below to find the ideal method, amount of ore, and coal to produce a particular bar.

• Bar Dispenser 

Because the bar dispenser will require time to cool down before you can take bars, you will need either a bucket of water or a pair of ice gloves to cool it down quickly enough to get the best experience rates. There is a bucket spawn in the blast furnace, and you can use the water pump to fill it with water, or you can wear the ice gloves and click the bar dispenser to collect the bars even faster. Various bars can be made in the blast furnace, and they have different methods of making them, which are listed below; most of these bars are quite profitable when made in the blast furnace, while some of them have lower smithing level requirements. It is recommended that you have at least 60 Smithing to avoid paying the blast furnace entrance fee. The profits shown below presume you use full graceful to save money on stamina potions; using the methods below without full graceful will significantly lower the mentioned profits.

Tip: Install a Blast Furnace helper plugin (Runelite) — it shows timing and necessary actions.

Bronze Bars (Level 1 Smithing)

At the Blast Furnace, they’re very fast to produce and are useful for learning the flow before moving to higher-tier bars.

How to run them: 

1. Fill your inventory with copper and tin ore (half and half)
2. Deposit them on the conveyor
3. Then collect bars from the dispenser. 
4. Go to the bank and repeat.

  XP/hr: 10,000–20,000

Iron Bars (Level 15 Smithing)

Iron bars are made from single iron ore; the Blast Furnace makes iron one of the fastest bars per hour because you don’t need extra ores for the bar itself.

How to run them: 

1. Bring full inventories of iron ore
2. Use the conveyor to deposit them
3. Run to the dispenser and collect with Ice Gloves. 

The Blast Furnace processes iron very quickly, and iron has a 1:1 ore → bar ratio at the furnace, letting you produce a large number of bars.

  XP/hr: 50,000–60,000

Silver Bars (Level 20 Smithing)

Silver bars are produced from silver ore and give modest Smithing XP. Silver bars are made with a Single Silver Ore in a 1:1 ratio.

How to run them: 

Load silver ore onto the conveyor and collect the bars at the dispenser, simple.

  XP/hr: 70,000–90,000

Lead Bars (Level 25 Smithing)

Unlike the ones we just saw, lead bars are not made with a 1:1 ratio but a 2:1 ratio, meaning that 2 ores are required to make just 1 bar of this type.

How to smelt at the Blast Furnace efficiently:

1. Withdraw a full inventory of lead ore from the bank.
2. Deposit the ores onto the conveyor belt.
3. Once the bar output is ready and cooled (with a bucket of water or Ice Gloves), collect all bars from the bar dispenser.
4. Bank the bars, then withdraw a new inventory of lead ore, and repeat.

  XP/hr: 45,000-55,000

Steel Bars (Level 30 Smithing)

Steel bars are a good mid-game option if you’re not ready for gold yet. Since steel requires a mix of iron ore + coal, having a coal bag is strongly recommended.

Method Overview:

1. Fill the coal bag and inventory with coal.
2. Load all the coal into the conveyor.
3. Withdraw from bank and load a full inventory of iron ore.
4. Collect bars with Ice Gloves or a bucket of water.
5. Repeat.

Steel is a great balance between profit and experience early on.

  XP/hr: 50,000–60,000

Gold Bars (Level 40 Smithing)

Gold is the go-to method for players who want the fastest Smithing XP possible. This ore/bar is made with a 1:1 ratio.

How to Do It:

1. Wear Goldsmith Gauntlets
2. Withdraw a full inventory of Gold Ore from your bank
3. Deposit ore onto the conveyor belt
4. Wait at the dispenser
5. Once the XP drop appears → quickly switch to Ice Gloves
6. Withdraw bars
7. Bank, re-equip gauntlets during the run, and repeat
8. If you forget to swap gloves before XP drops, you’ll lose a huge amount of experience, so you must get the hang of it.

  XP/hr: 300K–380K (Fastest XP in the game from 40–99)

Only efficient with Goldsmith Gauntlets

The XP here is unmatched — many players go 40→99 entirely using gold.

Mithril Bars (Level 50 Smithing)

Mithril bars require a mithril ore + 4 coal per bar, so the process involves alternating inventories.

Method Overview:

• Load full mithril inventory 
• Load the full 2 coal inventory
• Collect bars → bank → repeat
  
  

  XP/hr 57,000–67,000

Adamant Bars (Level 70 Smithing)

Adamantite requires a 6 coal per ore ratio, so expect more banking trips.

• 2 runs of coal
• Then 1 run of Adamantine Ore + coal bag

Same flow as mithril, just more coal loading.

  XP/hr 90,000–105,000.

Cupronickel Bars (Level 74)

To make these types of bars, a specific amount of ore is needed, such as 2 copper ore and then 1 nickel ore for each bar we want to make.

Smelting Process (Blast Furnace):

1. Withdraw and deposit a 2 full inventory of copper ore
2. Get back to bank and use a full inventory of Nickel ore
3. Once processing completes and bars are cooled, withdraw the bars using Ice Gloves or a bucket of water.
4. Bank the bars, re-stock ore, and repeat.
   
   

Runite Bars (Level 85 Smithing)

This is the final tier and is one of the best money-making methods while training Smithing.

Runite bars require a lot of coal, so expect multiple ore runs per cycle.
With optimal clicks, this becomes both good XP and massive profit per hour.

The process is coal-heavy and requires:

• 3 runs of coal
• Then 1 run of Runite Ore + coal bag
  
  

  XP/hr: 100K–120K

One of the most profitable methods in OSRS

Blast Furnace features

Coffer

Here you can deposit as many coins as you want, depending on how long you want to use the ability. Keep in mind that if you go AFK, the timer will continue to run, and the coins in the coffer will be spent.

The Blast Furnace foreman

Is the dwarf in charge of ensuring that no one with less than 60 Smithing can use the dwarves' service to use the Blast Furnace. If you don't meet that requirement, you can use it for 2,500 coins per 10 minutes.

Bucket and water

If you don't have ice gloves, you can take a bucket, fill it with water, and every time you make a trip to collect the bars, you'll have to use the bucket of water to cool them down so you can take them to your bank.

Standard Bars & XP Rates

The best experience rate is obtained from smelting gold bars at level 40 Smithing.

When using the Goldsmith gauntlets, you can expect up to  380,000 experience per hour.
 

Money Making

Tips, Plugins & Efficiency Boosts

•   Train Agility beforehand — upgrades like Graceful outfit help a lot.
•   Use the Blast Furnace Helper plugin if using Runelite — it visually guides your cycles.
•   Always check Grand Exchange prices. Sometimes gold bars are cheap; sometimes rune bars are more profitable.
•   Keep run energy high — stamina potions are NOT optional at high XP rates.

Conclusion

Whether you want to quickly reach 99 Smithing or passively increase your Smithing skill while making money, Blast Furnace is definitely the minigame for you. It might seem frustrating at first, and you'll probably fail some of your loads, but with consistency, it will become second nature, and much faster after reading this guide. Good luck!
