Blast Furnace Minigame
The Dwarven Blast Furnace is located under the factory in Keldagrim, the Dwarven city (east side of the city, northe-ast from the carts.) It can be used by anyone, but for players under level 60 Smithing, there is a 2500 coin fee (or 1250 gp wearing a Ring of charos (a)). This fee is well worth it because the Blast Furnace only requires half as much coal to smelt bars as a regular furnace. After making the payment, you will have access for 10 minutes after which you'll need to pay the fee again in order to continue using the furnace. That means that Steel bars take only 1 Coal, Mithril 2 Coal, Adamantite 3 Coal and Runite 4 Coal. The full amount of Smithing experience points are still earned. This minigame is slightly awkward without help; if you prefer not to solo it, go there with some friends, or if you don't find anyone operating the furnace, Jagex suggests World 58.
You will need a hammer, bucket, and spade. If you don't have those items, there are spawns of each item in the Furnace Room. The hammer respawns on the north edge of the room, the bucket next to the sink in the south, and the spade next to the coke box at the easternmost edge of the furnace. Bring your ore of course (or bring noted ore and coins to get it unnoted, if desired).
Furnace and Stations
When you go down the stairs into the Furnace Room, you will see three dwarves: two in the north-west, Ordan and Jorzik (see Shops), and one in the south, the Blast Furnace Foreman.
Talk to the Blast Furnace Foreman and he will explain all the stations in the Furnace Room. Note that in addition to the experience listed below for each station, everyone who works on the furnace also gets some smithing experience as well. When all the stations are working correctly, the furnace will start smoking and steam will come out of two pipes.
Ordan's Ore seller shop sells every ore up to Mithril, and his stock gets replenished gradually over time (maximum stock is 100 of each). Remember, if you are paying to use the furnace, you must pay again if you leave and come back.
However, players can use Ordan's store to change their ore notes into ore for smelting in the furnace. It costs some cash, but most people prefer this method over a trip to the bank. Do *not* sell your ore to him and then buy it back; instead, use your notes on him and he will un-note the ore for a small fee. Bring plenty of cash!
Jorzik's Armour store buys and sells all types of armour (helms, platebodies, legs/skirts, shields, and chainbodies) from Mithril up to Rune. The normal stock level is zero; all items are supplied by player smiths. He pays the high alchemy value for the first item if he has none in stock.
Smelting and Smithing
To smelt your ore, walk up the ramp on the north-west side to the conveyor belt and use your ore on it. If you click on the conveyor belt, it will ask if you'd like to deposit all of your ores on the conveyor belt at once. You will not lose your ore in the furnace; the game keeps track of what you have deposited and it cannot be picked up by other players. However, do *not* leave ores on the conveyor belt - if you log out, you will lose them.
If the furnace is being operated properly, you will see your ore move along the conveyor belt until it drops into the furnace. A little while later, the bar mould on the Bar dispenser will fill up and glow orange. Either use a bucket of water on the bars or wait for them to cool down and then collect them.
If you want to smith your bars, there are two places you can go. The first place is the fenced area of anvils in the north-west corner of the Blast Furnace room, but this is only available to players with level 60 Smithing. The second place is north of the general store on the west side of Keldagrim, or the smithy west of the bank.
The furnace will accept up to 201 coal from you. It will accept up to 28 (one packload) of each other type of ore (except iron; see below). Your unused coal "balance" is shown in the lower right corner of the bar dispenser menu. All deposited ores are held for you in the furnace indefinitely; they don't expire.
The bar dispenser will only hold up to 28 bars - you will not be allowed to make more bars until you remove some finished bars. Be aware of this when adding iron ore. If you have coal in the furnace, up to 28 steel bars will automatically be made, and then up to 28 iron bars will be made. Note that the Blast Furnace has a 100% success rate when smelting iron ore into bars. The normal amount of smelting experience per bar is earned here, the same as using a regular furnace. This experience includes bonus experience obtained when smelting Gold wearing Goldsmith Gauntlets, obtained after the Family Crest quest.
If you can't smith high level items for sale or high alching, you may wish to smith stackable items such as knives or arrow tips.
Soloing the Furnace
When the Blast Furnace was first introduced, the number of tasks required made it difficult to perceive that one person could run it alone. However, it is quite possible.
How to efficiently use it
Note: This section is purely a suggestion, there are other methods. However, this one is probably the best. This method requires 60 smithing.
The blast furnace requires quite a lot of work, so it's best to be with as many people as possible. The more people are working the furnace, the less work you have to do, so the more time you can devote to the actual smithing. Because of that, it's suggested to use the themed world.
Mithril is probably the most efficient bar to smith. It saves more coal than steel and Ordan can't un-note any higher ores. The rest of the guide will use mithril as the prime example, but it can easily be expanded to other bars and ores.
What to do
The reason behind this method is a lot of the smelting takes place when you're busy (either by putting more ores in the machine or smithing your bars). So you can devote the most time to the actual smithing and you waste the least time keeping the machine running (which gives no smithing xp).
