Introduction

The Blast Furnace OSRS is one of the most efficient and cost-effective methods for training Smithing in Old School RuneScape (OSRS). This minigame-like activity allows players to smelt bars using half the required coal compared to a regular furnace, making it an excellent choice for both experience gain and profit-making. In this guide, we will cover everything you need to know about the Blast Furnace OSRS, including its location, requirements, mechanics, best training methods, and money-making strategies.

What is the Blast Furnace in OSRS?

The Blast Furnace OSRS is a special furnace located in Keldagrim, the dwarven capital. Unlike regular furnaces, it is designed to smelt ores more efficiently by reducing the coal needed by half. This makes it one of the best methods for smelting high-tier bars, such as mithril, adamantite, and runite, which usually require a lot of coal.

How to Access the Blast Furnace OSRS

Location

The Blast Furnace OSRS is located in Keldagrim, which can be accessed in several ways:

• Using the Minigame Group Finder: This is the fastest way to get to the Blast Furnace. Simply open the minigame teleport menu and select “Blast Furnace.”
• Minecart System: Players who have completed The Giant Dwarf quest can use the minecart transport system from various locations, such as the Grand Exchange.
• Fairy Rings: The closest fairy ring is DKS, but additional travel is required.
• Using a Keldagrim Route via the Fremennik Province: Players can enter via Rellekka after starting The Giant Dwarf quest.

Requirements

To use the Blast Furnace OSRS, players must meet the following requirements:

• At least level 15 Smithing (required to smelt iron bars and higher-tier metals efficiently).
• Start The Giant Dwarf Quest to access Keldagrim.
• 60 Smithing or pay 2500 coins per 10 minutes if below level 60.
• Coins to pay the dwarven workers (unless using a designated world where players collectively pay for the furnace).

How the Blast Furnace Works

The Blast Furnace OSRS operates differently from a normal furnace. Instead of using a conventional smelting process, it relies on dwarven mechanics and requires the following steps:

1. Deposit Ore and Coal: Players must place their ores and coal onto the conveyor belt.
2. Pump the Furnace: The furnace must be kept running by operating the pump (this is usually done by an NPC in designated worlds).
3. Cool the Bars: Once the ores are smelted, players must use the bar dispenser to collect their smelted bars.
4. Retrieve the Bars: Players must collect bars using a bucket of water to cool them down and then pick them up.

Tips for Maximizing Efficiency at the Blast Furnace OSRS

• Use coal bag and ice gloves: The coal bag allows you to carry extra coal, while ice gloves eliminate the need to use a bucket of water to cool bars.
• Plan inventory efficiently: Always keep your ore, coal, and any necessary equipment optimized for fewer trips.
• Utilize a Bank Chest: The nearby bank chest allows for faster restocking of ores.
