Blast Furnace

The blast furnace is a very useful minigame situated in Keldagrim for smelting bars which require coal. The furnace here only require half as many coal as when smelting usually so can be useful when smelting the ores that require more coal. It is designed to be used by a team but it can also be worked by a single player if the correct strategy is followed. It can be played as a team yet it is still very easy to play individually.

Note :  Blast furnace is a safe minigame, however player may be injured, round 16 hp, while using the heat pump.

Reaching the Furnace
There are many ways to reach Keldagrim :
 * Using the train from Dwarven Mine or Dorgeshuun
 * Walk from relleka or seer village
 * Fairy ring code D-K-S (north east of Keldagrim entrance)

The blast furnace is in the south east of keldagrim, near the train station, in the building cave.

Skills Requirements

 * Smithing level 60 or 2500 coins for the furnace entrance fee (1250 coins when wearing an activated Ring of charos)
 * Firemaking level 30, for fueling up the stove.
 * Strength level 30, for pumping the stove.
 * Agility level 30, for pedaling the conveyor belt.
 * Crafting level 30, for fixing the broken pipes.

Note :  for teams, all of the following level requirements must be met for the team overall, not for each individual.

Quests Required
There is no quests required to use the blast furnace, but a player may reach keldagrim faster with the help of two quests.
 * If players plan to reach keldagrim by dorgesshun train, they should finish Another slice of H.A.M. quest.
 * If players plan to reach keldagrim using Fairy ring, they should begin A Fairy Tale Part II quest.

Getting Ores
This can be done in three ways :
 * A player can either bring all the ore in note form (up to Mithril, as that is the highest the shop stocks) and bring cash to un-note them by selling them to the ore store and buying them back.
 * A player can buy all the ore from Ordan the shop keeper, and change world if there is no ore left.
 * A player can take trips to and from the bank, if the player wishes to bank the bars. If a player wishes to mine all their own coal then there is a small coal mine north of the blast furnace that would be very useful.

Tips : There are many different suggestions on where to bank the bars, if the player wishes to do it that way (including Ring of Dueling and Games necklaces) but it is also possible just to walk to and from Keldagrim bank.

Remark :  Every 15 seconds the shop is restocked by a dwarf that enters the room and gives a large number (around 30) of one random type of ore to Ordan, once there is 100 ore of one kind in stock, the surplus is send in another unknown storage...

Suggested Equipment
There are two main strategies which require a few items :
 * Nature Rune if player wish to high alch
 * Staff of fire if player wish to high alch
 * Ores depends of the player strategy
 * Coins to buy Ordan's ores.
 * Charos ring to pay a lower fee if player smithing level lower than 60 (2500 or 1250 coins)
 * Spade to refuel stove (respawn near stove)
 * Hammer to repair pipes and to smith (respawn on a table)
 * Bucket to cool down ores (respawn near sink)

Conveyor Belt
First of all, players have to put their ores in the conveyor.

Due to dwarf science, the blast furnace is requiring twice less coal to make bars, which means :
 * Steel : 1 coal
 * Mithril : 2 coal
 * Adamantite : 3 coal
 * Runite : 4 coal

Player have to put both coal and ores to get bars. There is no particular order, but the Conveyor belt capacity is limited :
 * There is a coal maximum of 254 in the furnace.
 * There is a metal ore (every ores but coal) maximum capacity of 28 in the furnace.
 * If a player puts in metal ore first, the coal capacity will decrease by the number of metal ore put in. Example : 10 mithril ores, means a coal capacity of 244.
 * If a player tries to put more ores in than possible, the following message will advert him : "?"

Remark : The ores a player puts in the conveyor can't be stolen by other players.

Once the different ores are put in the conveyor belt, the player has to activate the belt to move ores into the furnace. To do so the player has to use a kind of bicycle.

Sometimes, one of the conveyor's cogs break, the player will have to fix it with a single hammer.

Furnace Stoke
Once ores send in the furnace, player have to raise its temperature, to do so he will have to put coke, which is refined coal, in a stove. Player should first get a spade, collect coke with the spade and put it in the stove. Both of these actions require a single click.

There are three temperature level indicated on the upper part of the stove by a color :
 * cold : light orange
 * warm : orange
 * extremly warm : red

It is recommended that players put enough coke in stove until it turns red.

Note :
 * The stoke never explodes, even if a player adds coal continually.



Heat Pump
Once the stove temperature raised to red, player have to activate the heat pump, to raise the furnace temperature, by clicking on the pump. Player have to continue to pump until one of the following event :
 * The bars are smelted.
 * One of the pipe is broken

Note :
 * Player may be injured, around 16 hp, while using the heat pump.
 * If a player forgets to put metal ore (every ore but coal) in the furnace he will be injured while using the pump.
 * There is no need to check the gauge.

Bar Dispenser
Once the bars are melted, the bar dispenser turn to a golden colour. Player have to cool them down with a water fill bucket before getting them.

Remark :
 * Player can smelt up to 28 bars at once.
 * Player must get bars to be able to add more ore (except for coal)

Single player strategy


A single player is able to manage the blast furnace.


 * 1) Collect the materials in the desired way.
 * 2) Place them on the conveyor belt (just left click on the belt to put them all on at once) with the correct ratio (1 iron ore + 1 coal ore, 1 mithril ore + 2 coal ore, 1 adamant ore + 3 coal ore).
 * 3) Pedal the conveyor belt so that the ores go into the furnace. Repair conveyor belt if conveyor jammed.
 * 4) Collect the Hammer and spade from their respawn places in the room (Hammer: North East corner on a table, Spade: On the floor next to the re-fuel area).
 * 5) Now to fuel up the machine. There is no point only putting in a little fuel as it will run out when it's needed so it is important to put enough in. Click on "collect coke" and then "Refuel Stove". To know if you have put enough in notice the colour of the three lines on the stove, the more fuel you put in the colour changes from brown to orange then finally to red. When it is red there is enough fuel.
 * 6) Now to move onto pumping the machine. First check that there are no pipes broken. If there are click on them and you will repair them with your hammer.
 * 7) Start pumping. There is a common belief that the player must check the gauge. This isn't strictly true. While pumping, position the 'camera' so that one can see the bar dispenser, the pipe and the stove temperature, as shown on the upper image.
 * 8) Repair any pipes that break while pumping. Sometimes many will break and it will take a while, sometimes none will break.
 * 9) When the bar dispenser turn a golden colour (and if the sound effects are on one will hear a kind of fire noise), stop pumping as the bars are done. Otherwise, you will be hurt by the hot air.
 * 10) Collect the bucket and fill with water from the sink and use bucket with the bar dispenser.
 * 11) Collect the bars.

Team playing
Team playing on the Blast Furnace is much easier than attempting it yourself as people can assume different jobs so a single person doesn't overwork himself over multiple tasks and spreads the jobs evenly among fellow players. This option also allows for the faster gathering of experience.

As with most minigames in RuneScape, there is a world that many players will go to if they wish to work as a team. The official world is world 58. At some times this world can be very busy.

High level ores
One effective way is to bring 200 noted coal and 25 unnoted runite ore, roughly 30,000 coins, 5 nature runes and a fire staff. Put all of the runite ores on the conveyor then by using the method of noting and unnoting in the shop put all the coal on the conveyor too. As the prices to buy the ores back fall as the stock in the store increases it may be advisable to make sure as many ores are sold to the store as possible to decrease overall cost. It is important to realise that there is a coal maximum of 254 in the furnace. A player can't put more than this on conveyor and/or furnace.

After making the bars, a player can smith them and use High Level Alchemy on the smithed items. This means the player can run for longer when going back to the bank and the furnace is now ready for its next load.

Mithril processing
The dwarf Ordan sells all types of ore up to mithril. This allows a player to train smithing without mining ores. Buy mithril and coal from Ordan in the ratio two coal for each mithril. Make two trips of 25 coal and another for 25 mithril. Operate the blast furnace to obtain 25 mithril bars. Smith them into 5 mithril platebodies. After high alching the smithed items, a small profit remains (excluding the cost of the nature runes). Bringing a few hundred nature runes allows a player to repeat this until the shop runs out of ores. Generally the coal supply runs out first. Hence, players need to switch to another world or bring their own noted coals. Note that processing of 25 ores/bars requires a bit of inventory management. Use the spade and hammer respawns for this.
