Iron Ore Blast Furnace OSRS Ultimate Guide for Smithing and Profits

The Blast Furnace in Old School RuneScape (OSRS) is a powerhouse for players looking to smelt iron ore into bars efficiently while racking up Smithing experience and potential profits. Located in Keldagrim, this members-only minigame offers a unique smelting experience that halves coal requirements for most bars, making it a go-to for iron ore smelting. Whether you’re a low-level smith or an Ironman chasing efficiency, this guide dives deep into mastering iron ore smelting at the Blast Furnace, optimizing your setup, and maximizing rewards.

The Blast Furnace stands out for its ability to smelt iron ore into bars with 100% success, unlike regular furnaces where iron smelting has a 50% failure rate without aids like the Ring of Forging. It’s particularly appealing for iron bars, which are in demand for low-to-mid-level Smithing projects. Here’s why it’s a game-changer:

100% Success Rate: Iron ore smelting at the Blast Furnace guarantees bars, boosting efficiency.
High Output: Produce up to 5,800 iron bars per hour with optimal setups.
Profit Potential: Iron bars (worth ~299 GP each) can yield up to 340,000 GP/hour after costs.
Low Requirements: Only level 15 Smithing is needed, though level 60 is recommended to avoid fees.

This makes the Blast Furnace ideal for players aiming to level Smithing quickly or make money without high skill requirements.

Key Benefits for Ironman Accounts

Ironman players benefit immensely, as the Blast Furnace reduces reliance on mining excessive coal and ensures consistent bar production. It’s a time-saver for crafting cannonballs or other iron-based items, especially since you can buy ore from Ordan’s shop nearby when stocks are high.

Requirements and Setup for Blast Furnace

Before diving into the smelting process, you need to meet certain requirements and prepare your inventory. Accessing the Blast Furnace is straightforward but requires some setup.

Quest and Skill Requirements

Quest: Start The Giant Dwarf quest to unlock Keldagrim. No completion is needed, just begin it by speaking to the Dwarven Boatman east of Rellekka.
Smithing Level: Level 15 to smelt iron bars, but level 60 is highly recommended to skip the 2,500 GP fee every 10 minutes.
Coins: 72,000 GP/hour on official Blast Furnace worlds (Worlds 352, 355, 358, 386, 387) to pay the dwarves operating the furnace. Below level 60, add 2,500 GP every 10 minutes unless using the Ring of Charos (a) to halve it to 1,250 GP.

Recommended Gear and Inventory

Optimizing your gear and inventory is crucial for efficiency. Here’s a suggested setup:

Item	Purpose
Ice Gloves	Instantly cool bars, replacing the need for a bucket of water.
Weight-Reducing Clothing (e.g., Graceful)	Reduces run energy depletion while carrying heavy ore.
Stamina Potions	Restores run energy for continuous trips.
Coins	Pays the 72,000 GP/hour fee or 2,500 GP/10 mins if below level 60.
Iron Ore (25-28)	Main resource for smelting, filling inventory slots.

Pro Tip: Equip Ice Gloves (obtained from the Ice Queen in White Wolf Mountain) to free up an inventory slot, replacing the bucket of water. Use weight-reducing gear like the Graceful outfit or Spottier Cape for maximum run energy efficiency.

How to Smelt Iron Ore at the Blast Furnace

Smelting iron ore at the Blast Furnace is a simple yet repetitive process, especially on official Blast Furnace worlds where dwarves (Dumpy, Stumpy, Pumpy, Numpty, and Thumpy) handle mechanics, letting you focus on ore delivery and bar collection.

Step-by-Step Smelting Process

Travel to Keldagrim: Use the minigame teleport, minecart system from the Grand Exchange, or travel via the Dwarven Boatman.
Deposit Coins: Place 72,000 GP in the coffer near the bank chest on a Blast Furnace world to cover the hourly fee (1,200 GP/minute).
Withdraw Iron Ore: Fill your inventory with 25-28 iron ores (27 if using a bucket, 28 with Ice Gloves).
Deposit Ore: Click the conveyor belt to place all iron ore at once (disable confirmation for speed).
Collect Bars: Click the bar dispenser with Ice Gloves equipped,指標
