OSRS Blast Furnace Guide 2026 - Fastest Smithing XP and GP/Hr Breakdown

February 13, 2026 · By D

TL;DR: Blast Furnace is still the best Smithing training method in the game for both XP and profit. Gold bars with Goldsmith Gauntlets hit 380k+ XP/hr. Runite bars print 800k-1M GP/hr. The coal bag is non-negotiable. Here’s everything you need to know heading into 2026. Look, Smithing is one of those skills where the “right” method saves you tens of hours and millions of GP. And in 2026, the Blast Furnace is still king. Giants’ Foundry took some of the spotlight, sure. But if you want raw speed or consistent profit, nothing beats cranking bars in Keldagrim.

I’ve spent way too many hours at this minigame across multiple accounts. Here’s the no-BS breakdown.

What Is the Blast Furnace (and Why Should You Care)?

The Blast Furnace is a minigame located in Keldagrim that lets you smelt bars using half the normal coal requirement. That’s the whole pitch. Half coal means faster banking cycles, cheaper inputs, and better margins on every bar you make.

You need to complete The Giant Dwarf quest to access it. Takes maybe 20 minutes if you have the reqs ready. Key detail: On official Blast Furnace worlds (Worlds 352, 355, 358, 386, 387, 395), other players run the machinery for you. You just load ore, collect bars, repeat. Off these worlds, you’d need to operate the conveyor belt and pumps yourself. Don’t do that. Stick to the designated worlds. If you’re under 60 Smithing, you’ll pay a fee of 2,500 GP every 10 minutes to the foreman. After 60, it’s free. Getting to 60 first through something like Knights Swords quest + Iron/Steel bars is worth the small time investment.

Requirements and Setup

Here’s what you need before you step foot in Keldagrim: Hard Requirements:

The Giant Dwarf quest (started, not even fully completed)
60 Smithing (or pay the foreman fee)
Coins for the coffer (at least 72k covers an hour of foreman fees if under 60) Strongly Recommended:
Coal Bag from Motherlode Mine (81 Nuggets). This is mandatory for anything involving coal. Doubles your coal per trip.
Ice Gloves from the Ice Queen under White Wolf Mountain. Lets you grab bars straight off the bar dispenser without cooling them with water.
Goldsmith Gauntlets from the Family Crest quest (for gold bar XP method).
Stamina Potions. You’re running back and forth constantly. Bring 3-4 doses per hour minimum.

| Item | Source | Priority |

|------|--------|----------|

| Coal Bag | Motherlode Mine (81 nuggets) | Essential |

| Ice Gloves | Ice Queen (White Wolf Mountain) | Essential |

| Goldsmith Gauntlets | Family Crest quest | Essential for XP |

| Stamina Potions | GE / Herblore | High |

| Weight-reducing gear (Graceful) | Rooftop Agility | High | Your inventory setup is simple: Stamina pot, coal bag (if using coal), and the rest is ore. Some people bring a ring of wealth or a gem bag. I don’t bother. Keep it clean.

Methods, XP Rates, and Profit

This is where it gets good. The Blast Furnace has two distinct use cases: training for XP and making money. Different ores, different goals.

Gold Bars (Maximum XP)

Equip your Goldsmith Gauntlets. Fill your inventory with 27 gold ore. Run to the conveyor, deposit, collect bars, bank, repeat. XP Rate: 350k-390k/hr depending on your click speed and latency. You’ll lose a small amount of money per bar since gold bars sell for less than gold ore on the GE. Last I checked, the loss was around 50-80 GP per bar. Over an hour that’s maybe 150k-200k GP lost. Honestly, that’s nothing for 380k Smithing XP/hr. Cost of doing business.

Tip: You can swap to Goldsmith Gauntlets right before collecting bars and use Ice Gloves when picking them up. But the tick timing is tight and honestly not worth the hassle for most people anymore. Just wear the Goldsmith Gauntlets the whole time.

Steel Bars (Decent XP + Profit)

Steel bars have always been the “do both” option. Reasonable XP and you actually make money.

XP Rate: ~85k-95k/hr
Profit: ~200k-350k GP/hr (fluctuates with GE prices) The process: fill coal bag with coal, fill inventory with coal, deposit on belt, empty coal bag on belt, bank, fill inventory with iron ore, deposit, collect steel bars. Rinse and repeat.

Mithril, Adamantite, and Runite Bars (Money Makers)

Here’s where the Blast Furnace earns its reputation as a money printer.

|-----|-------------|-------------------|-------------------|-------|

| Steel | 30 | 1 | 200-350k | ~90k |

| Mithril | 50 | 2 | 300-500k | ~105k |

| Adamantite | 70 | 3 | 400-650k | ~115k |

| Runite | 85 | 4 | 800k-1.1M | ~125k | Prices shift constantly. Check the OSRS Wiki for current GE values before committing to a method. Runite bars are the money play. 85 Smithing is the barrier, but damn is it worth it. Even with ore costs, you’re looking at close to 1M GP/hr with good banking. The margins have compressed a bit since 2024, but it’s still one of the best skilling money makers in the game. Adamantite is my go-to recommendation for mid-level accounts. 70 Smithing isn’t hard to reach, and 500k+/hr while training is solid.

Efficiency Tips That Actually Matter

Use world 355 or 387 during off-peak hours. Less lag, smoother runs. Peak times (weekends, evenings GMT) can cause the bar dispenser to feel sluggish.
Pre-load the coffer. Throw 500k-1M in the coffer near the entrance so you’re not interrupted. Nothing worse than getting booted mid-run because your payment lapsed.
Bank layout matters. Set up your bank tab so your ore, coal bag, and stamina pots are right there. Every tick you waste searching your bank is XP and GP lost. I keep a dedicated tab just for Blast Furnace supplies.
Bring exact stamina doses. 3-4 dose potions, 3 per hour is usually enough if you’re in full Graceful. Don’t bring more than you need. Inventory space is everything.
Use the bank chest, not the bank booth. The chest right next to the bar dispenser saves a couple ticks per cycle. Small thing, adds up over hundreds of trips.

Real talk: The difference between a sloppy Blast Furnace session and a focused one is like 15-20% efficiency. That’s 60-70k XP/hr difference on gold bars. Pay attention for the first 5 minutes until muscle memory kicks in, then throw on a podcast.

Is Blast Furnace Still Worth It in 2026?

Short answer: yes. Giants’ Foundry is a solid alternative if you hate the click intensity, and it’s better for Ironmen working with platebodies. But for pure XP/hr or pure GP/hr, Blast Furnace hasn’t been dethroned.

Jagex hasn’t made any significant changes to the minigame recently, and the official worlds still run smoothly with player-operated machinery. The economy around bars stays healthy because of PvM alch values and construction demand.

If you’re building an account and need 99 Smithing, gold bars at the Blast Furnace will get you there in roughly 35-40 hours from level 40. That’s fast for a 99. And if you need cash, runite bars are still printing.

So yeah. Learn the rhythm, get your coal bag, and get to work.
