OSRS Blast Furnace Guide

OSRS Blast Furnace Guide

The Blast Furnace in OSRS is a blacksmithing-based activity that can provide an incredible amount of experience if the right materials and payments are used. Using a blast furnace, players can smelt metal ingots in bulk.

Of course, mass smelting these ingots requires a ton of raw materials, including various ores and coal. However, the catch with the Blast Furnace is that higher tier ingots such as Mithril, Adamantine, and Rune require half as much coal to smelt.

In addition to these raw res, the Blast Furnace also requires a certain amount of GP to use. Players under 60 will be required to pay 2,500 coins for every ten minutes spent in a blast furnace.

Since the Blast Furnace requires a lot of res and money, players will lose GP when using the Furnace. That being said, the insane blacksmithing rates of mass smelting are seen as a good compromise. To capitalize on these great experience scores, follow this OSRS Blast Furnace guide.

Blast Furnace Unlock

As with most minigames and activities in Old School RuneScape, the blast furnace must first be unlocked by completing a quest. The crucible is located in the dwarven city of Keldagrim, for which you need to start (completion is optional) the quest “Giant Dwarf”.

The Giant Dwarf quest requires 12 crafting, 16 fire, 33 magic, and 14 theft. You can start this quest by talking to the transport dwarf in the dungeon east of Rellekka, south of Olaf. It is very close to Fairy Ring DKS.

Blast Furnace Recommendations

Before you get started with the OSRS blast furnace, there are a few more tips you should be aware of. These are not difficult requirements, since you can work just fine with or without the oven, but they will greatly improve the quality of your life.

The first of these recommendations is ice gloves. Freshly smelted ingots will be too hot for your character, so they need to be cooled with a bucket of water. Using ice gloves allows them to automatically cool down and saves inventory space.

The second of these recommendations is to use the furnace on one of the official Blast Furnace worlds. These include worlds 352, 355, 356, 357, 358, 386, 387, 395, 424, 466, 494, 495, 496, 515, and 516.

A blast furnace usually requires a group of five to six players to function properly, but in the aforementioned worlds, a group of NPC dwarves will take care of this, allowing you to focus solely on smelting the ore.

However, you must pay 72,000 gp per hour to use the Crucible in these worlds, in addition to paying up to 60 smithing. pretty hard.

The third recommendation, which is not as important as the other two, is a bag of coal from the Motherlode mine. This allows you to store extra coal, greatly reducing your trips.

Blast Furnace Operation

Now let’s move on to the actual operation of the blast furnace in Old School RuneScape. Since ores and ingots are very heavy, you need to wear weight-reducing equipment such as Fine Equipment, as well as ice gloves.

First, pay the Furnace Master, located south of the bank chest, your 72,000 gp for one hour. If you are under 60, you will need to pay him a little more. Then take the ore from the chest in the bank.

The further process depends on the ingots you are smelting. Typically, you will place ore on a conveyor belt and then take the smelted ingots from the ingot dispenser in the middle. Return the bars back to the jar, rinse and repeat.

However, the actual smelting process will differ depending on the amount of coal required to smelt the ingots you choose. Remember that you need half as much coal in a blast furnace as you normally would.

If you are smelting bronze ingots, simply fill your inventory with 14 copper ore and 14 tin ore. Place them on the conveyor belt, then take 14 bars from the dispenser. Take them back to the bank and repeat the process again.

To smelt iron ingots, fill your inventory with 28 iron ores. Place them on the conveyor belt, then take 28 iron ingots from the dispenser. Take them back to the bank and start over. This process is the same for silver ores/bars.

Steel is the first ingot to require coal and is therefore a bit more difficult. First place 54 coals on the conveyor. You have 28 spots in your inventory, so that’s two coal-only trips. Then make a third trip with only coal. There must be 81 coal in the furnace before you can bring iron ore.

From there, simply bring in 27 iron ores, collect 27 steel ingots, and start the process again. Remember that you need a one to one ratio of iron ore to coal in the furnace, otherwise you will end up with iron ingots instead.

Gold is considered by most players to be the best ingot for gaining Blast Furnace experience since it doesn’t require coal and you can use Jeweler’s Gauntlets. These are special gauntlets that give more experience when smelting gold. They can be obtained from the quest “Family Crest” or its continuation “Family Pest”.

In addition, you can save your gold bars for future use. For example, you can make rings, bracelets and necklaces out of them at the appropriate crafting levels.

To smelt gold, you just need to put 27 gold ores on a conveyor belt and then collect your 27 ingots. One space in your inventory will be taken up by your Ice Gloves, which you must put on when collecting ingots and then switch back to Jeweler’s Gauntlets. Then repeat the process.

However, smelting mithril requires some coal. To smelt it, start by placing 81 Coal x3 in the Furnace, then take 27 Mithril Ores. Gather your 27 ingots, then bring in 27 more Coal and then 27 more Mithril Ore. Collect your ingots a second time, then return to the original 81 coals.

You can then smelt Adamantite Bars in the Blast Furnace by loading three batches of Coal for a total of 81 and then adding 27 Adamantite Ore. From there, simply collect 27 Adamantite Ingots and repeat the process with 81 more Charcoal.

Finally, runite bars can be smelted with 85 Smithing and tons of coal. Start with six runs of 27 Embers each for a total of 162. Then add 27 more Embers for a total of 189. Add 27 Runite Ores and collect your ingots. From there, add 27 more coal, then 27 more ores. Collect your ingots, then return to the original 162 coals.

hybrid method

In addition, you can save the most time and money in the OSRS Blast Furnace by using the hybrid method of smelting gold, mithril, adamantium or rune bars. Using this method turns the bag of coal, jeweler’s gauntlets, and ice gloves from soft recommendations to hard requirements.

Start with a sack of coal and either ice gloves or jeweler’s gauntlets in your inventory. A pair of gloves that is not in your inventory must be equipped. The bag of coal must be filled with coal and the remaining 26 inventory slots must be filled with gold ore.

Every time you put 26 gold ores into the furnace, you also put 26 embers through the charcoal bag. Every few trips, when there is enough coal for the corresponding metal, you will save that metal instead of gold. This will happen every two Mithril Ore Runs, three Adamantine Ore Runs, and four Rune Ore Runs.

For example, when using the hybrid method for gold and mithril bars, you put in 26 embers from a charcoal bag, then 26 gold from the same inventory, and then collect 26 gold bars. On your next journey, you place 26 more coal from the bag and 26 more mithril ore, and then collect your mithril ingots.

On adamantite bars, you will put 26 gold, 26 coal, and then collect your gold bars. Then you contribute 26 gold and 26 coal, collect a second time. Every third trip, you deposit adamantite ore instead of gold along with 26 coals, and then collect your adamantite ingots.

For runite bars, you simply repeat the process of depositing 26 gold and coal, then collecting gold bars three times, and then depositing 26 runite ores and 26 coal on every fourth trip.

The rule is to put 26 embers from the charcoal bag on each trip to place gold or mithril/adamantine/rune ore. This increases your experience when smelting metal ingots, while reducing the money loss when smelting gold only.

Final Thoughts

The Blast Furnace in OSRS, while quite re intensive and requires a lot of clicks, provides an incredible level of blacksmithing experience, depending on the method used. Traditional methods involve placing multiple stocks of coal, then moving the metal ore onto a conveyor belt, then collecting the ingots from a batcher and restarting.

However, monetary losses can be reduced with minimal experience loss by using the hybrid method of smelting gold and higher tier metals at the same time. Using a bag of coal, you can invest 26 units of coal and 26 gold per trip and exchange gold for metal ore every few trips.
