Getting There

These are the fastest ways to get to the Blast Furnace.

1. Minigame teleport (requires the player to at least have started "The Giant Dwarf" quest)

2. Taking a minecart to Keldagrim. The easiest one is accessible on the west side of the Grand Exchange (requires the player to at least have started "The Giant Dwarf" quest)

3. Players can use the fairy ring DKS and run west to the cave entrance where players start "The Giant Dwarf" quest. This is the slowest route to get to Keldagrim and is not recommended

Blast Furnace Worlds

You should use the official worlds whenever training smithing at the Blast Furnace. This is because there are NPC workers there running all of the machines required in order for the Blast Furnace to function, thereby increasing your XP rates significantly.

There are 14 blast furnace worlds, with 3 for each region, except for 2 for Australia.

Items & Gear

Ores	Ores are required in order to smelt bars at the Blast Furnace. Depending on what type of bar you are trying to make, you will need the specific ores for it. Any bar that takes coal to make has its coal price halved whilst smelting it at the Blast Furnace.
Cooling Item	The best items for cooling bars, in order, are:1. Ice Gloves (These allow you to left click the bars right away and are highly recommended)2. Bucket of Water (There is a water source near the bank players can refill their bucket at)
Coal Bag	The Coal Bag is a reward that can be bought from Percy's Motherlode Mine shop. The Coal Bag costs 100 golden nuggets and allows the player to store up to 27 pieces of coal within it, effectively making coal based bars much more efficient.
Graceful Set	The Graceful set significantly reduces your weight which means you are using less run energy. Ores and bars are heavy so this is highly recommended to have.
