Blast Furnace

The Blast Furnace is a very useful minigame situated in Keldagrim for smelting bars which require coal. The furnace here only requires 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.

Requirements

 * Started The Giant Dwarf to gain access to Keldagrim.


 * Smithing level 60 or a 2500-coin (1250 coins when wearing a Ring of charos) entrance fee for 10 minutes; to utilise the furnace for smelting bars.

Note that for teams, all of the following level requirements must be met for the team overall, not for each individual.
 * Firemaking level 30, for fueling up the stove.


 * Strength level 30, for pumping the stove (Skillers can have someone else pump for them.)


 * Agility level 30, for pedaling the conveyor belt.


 * Crafting level 30, for fixing the broken pipes and parts of the pedaling machine.

Traveling and Getting to the Blast Furnace
A player can only visit the Blast Furnace after visiting Keldagrim. To visit Keldagrim, the player must have started or completed the quest The Giant Dwarf. The player does not need the levels or items required to start the quest, only to finish the quest. Once the player has visited Keldagrim, they can return via Mine-Cart from the Dwarven Mines under Ice Mountain. The player can also use the Quick Minigames Teleport to be teleported outside the Blast Furnace building. The Quick Minigames Teleport is listed in the Quest Tab under the Minigames (Red) Icon. To use this teleport, the player must have visited Keldagrim at least once. Alternatively, the player can also walk from Seers' Village to Keldagrim via the path shown on the map to the left. Once in Keldagrim, the player can run to the opposite side of the town from the bank.

Suggested Materials/Inventory Setups

 * Note: Remember to deposit coal first if not working with pure iron! A spade can be picked up to refuel the stove with spadefuls of coke after depositing your ores on the conveyor belt. Coins can also be used to purchase ore there from Ordan.


 * Note: IF YOU HAPPEN TO LOG OUT WHILE YOUR ORE IS ON THE CONVEYOR BELT, YOU'LL LOSE IT, SO MAKE SURE IT GOES DIRECTLY INTO THE MELTING POT TO AVOID LOSING ANY. THUS, DO NOT LOG OUT WHILE ORE IS LEFT ON THE BELT.

The suggested inventory for players BELOW 60 Smithing is coins, a hammer, an energy potion, and 25 ore.

The suggested inventory for players ABOVE 60 Smithing is a coal bag, which helps greatly, a hammer, a bucket of water, and 25 ore. An energy potion is optional!

Experience Rates
Full Smithing experience is gained from smelting the bars. There is an anvil nearby to smith any items you wish for additional experience. Magic experience can be gained should one choose to alchemise his or her produced items. Also, both Magic and Smithing experience can be gained should one Superheat his or her ore.

Additionally, maintaining the Blast Furnace also offers XP in other skills. However, this gives trivial XP:

At the Blast Furnace, the following Smithing XP can be gained producing bars. Moreover, the following assumes that the player has a coal bag, hammer, and bucket of water in his or her inventory, thus there are 25 inventory slots occupied by ore.

Bars
The number of bars per hour will vary depending on team size and how quickly pipes are fixed.




 * Bronze: 950 - 1,250 bars per hour
 * Iron: 1,500 - 2,000 bars per hour
 * Steel: 1,200 - 1,500 bars per hour
 * Gold/Silver: 1,500 - 2,000 bars per hour
 * Mithril: 700 - 1,300 bars per hour

XP (per hour)

 * Bronze: 6,000 - 7,000 XP per hour
 * Iron: 15,000 - 20,000 XP per hour
 * Steel: 20,000 - 25,000 XP per hour

ALL RATES WILL VARY DEPENDING ON YOUR ACTIVITY LEVEL IN THE MINIGAME AND THE TEAM'S LEVEL OF COOPERATION TO MAINTAIN THE MACHINE.

Collecting Raw Materials
Raw materials can be obtained in two ways: A player can either have ore in his or her bank, and use the bank chest conveniently located in the Blast Furnance itself, or buy ore from Ordan who runs the ore seller shop (up to mithril). Ordan usually sells ore for cheaper than street price while his stock is 50 or above, so many players choose to supplement their supply of banked ores by buying ore from Ordan when his stock is high. Therefore, on a busy world, Ordan's stock will often be at less than the max of 100 (which is especially true with coal).

Operating the Blast Furnace
The process for operating the Blast Furnace is as follows:
 * 1) Place coal and/or ore on the Conveyor Belt.
 * 2) Turn the Conveyor Belt by operating the Pedals.
 * 3) Repair cogs or drive belt (if broken) using a hammer.
 * 4) Collect coke via using the spade to refuel the Stove.
 * 5) Operate the Pump.
 * 6) Repair pipes (if broken).
 * 7) Cool down smelted bars with a bucket of water from the sink.
 * 8) Collect the bars from the bar dispenser.
 * 9) Repeat!


 * Note: Always keep your coal bag full, and focus your run energy toward putting the maximum amount of coal on the conveyor belt, which is 254, although 225 or 250 is a decent amount for optimal Smithing. Sometimes, it will only allow you to place up to 225 coal max until your bars are finished. If you have 200 coal or under, you can usually place more coal on the belt. Afterwards, place a full load of your primary ore. The max amount of primary ore that may be placed is 28. Replenish your inventory with your primary ore, and place it on the belt after bars have been produced so that your bars can be processing while you bank your made bars.

Single-player Strategy


This can be hard work but it works.


 * 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). Remember to place coal first if working with steel, mithril, adamant, or rune with the correct ratio of ores (1:1 iron to coal, 1:2 mithril to coal, 1:3 adamantite to coal, and/or 1:4 runite to coal). For the long haul, place 25 pieces of coal on the belt ten times (250 coal total) and then a load of 25 of your preferred ore afterwards each time.
 * 3) Pedal the conveyor belt so that the ores go into the furnace. Repair the drive belt or cogs if jammed.
 * 4) Collect the hammer if you didn't bring one and/or the spade from their respawn places in the room. The hammer spawn point is in the north-east corner on a table, and the spade spawns on the floor next to the re-fuel area.
 * 5) Now, fuel up the machine. There's no point in only putting in a little fuel as it will run out when it's needed, so it's important to put enough in. Repeatedly click on "Collect Coke" and then "Refuel Stove." Notice the colour of the three lines on the stove to know if you've put enough in. The more fuel you put in results in the colour changing from brown to orange and then finally to red. When it is red, there's enough fuel, but adding a dozen more spadefuls of coke helps greatly.
 * 6) Now, move onto pumping the machine. First, check that there are no pipes broken. If there are, click on them, and you'll repair them with your hammer.
 * 7) Start pumping! There's a common belief that the player must check the gauge, which isn't strictly true, so there's no need to check it. While pumping, position the 'camera' so one can see the bar dispenser, pipes, and stove top.
 * 8) Repair the drive belt, cogs, or any pipes that break while pumping. Sometimes, many will break and it will take a while; other times, none will break.
 * 9) When the bar dispenser turns a golden colour (and if the sound effects are on, one will hear a splat), stop pumping as the bars are done, or you'll get damaged by a blast of hot air.
 * 10) Collect the bucket if one isn't already in your backpack, and fill it with water from the sink, and use bucket with the bar dispenser.
 * 11) Collect the bars and repeat the whole process.

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 him or herself 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. This is World 358. At some times, this world can be very busy. At other times, it is less cluttered.

Possible Methods
There is a maximum of 254 coal in the furnace, but if a player manages to put in even more coal, he or she will lose the extra coal. There's also a max of 28 primary ore.

High-level Ores
All high-level ore, such as (adamantite and runite), must be in the player's bank as they cannot be bought from Ordan. Coal can be bought from Ordan, but the quantities required for high-level ore usually exhaust his stock after only making one inventory of bars. Therefore, it is recommended that players only use Ordan as a supplemental source and have most or all of the required coal in their bank.

Mithril Processing from the Shop
Ordan sells all types of ore up to mithril, which allows a player to train Smithing without mining ores. The process for smelting mithril bars is as follows:


 * 1) Purchase mithril and coal from Ordan in the ratio two coal per one mithril.
 * 2) Make two trips of 27 coal (or one trip if using a coal bag with a loaded inventory) and another trip with 27 mithril.
 * 3) Operate the Blast Furnace to obtain 27 mithril bars as described thoroughly in the aforementioned Single-player Strategy.
 * 4) Smith the bars into items and bank them or bank the bars directly using the Blast Furnace bank chest.
 * 5) One can repeat this until the shop runs out of ores. The coal supply generally runs out first; hence, players may need to switch to another world or supplement the store coal supply with banked coal.

Trivia

 * Contrary to popular belief, the temperature of the stove does not affect the chance of a pipe becoming broken.
 * The conveyor belt that moves the ores into the furnace has three separate sections turning independently. However, only the outer two are connected to the pedal mechanism; the inner one turns by itself.
 * In the Q&A on 11 February 2010, Paul Gower stated that the Blast Furnace was created during an attempt to make a Smithing Guild.
