Mithril Bars OSRS Blast Furnace Smelting Guide

You know that feeling when you’re staring at your Smithing level, hovering around 50, and wondering how to push forward without burning through your gold stack? Yeah, I’ve been there more times than I can count. As someone who’s sunk thousands of hours into Old School RuneScape, grinding skills from scratch on ironmen to maxing out alts, the Blast Furnace became my go-to spot for mithril bars early on. It’s not just about the experience points; it’s that sweet profit margin that keeps you coming back. Today, I’m breaking it all down for you, from the basics to those little tricks that separate the casual smelters from the furnace pros. Let’s dive in and get those shiny mithril bars flowing.

Picture this: you’re at a regular furnace in Falador, fiddling with one ore at a time, watching your coal vanish like it owes you money. Now flip that script. The Blast Furnace in Keldagrim? It’s a game-changer. This dwarven powerhouse lets you smelt batches of bars super quick, cutting your coal use in half for mithril. We’re talking about turning mithril ore and just two coals per bar instead of four. That alone saves you a bundle, especially when coal prices spike.

But here’s the real hook, especially if you’re like me and hate wasting time. At the Blast Furnace, you can crank out 3,000 to 3,700 mithril bars an hour with the right setup. That’s up to 111,000 Smithing XP per hour, folks. Compare that to superheating with Magic, where you’re lucky to hit half that rate while juggling runes. And profit? Oh man, after material costs, you’re looking at around 720,000 gold per hour. I remember my first long session there, back when I was leveling a fresh account. Walked away with enough cash to fund a bossing spree. It’s efficient, it’s profitable, and it feels rewarding when those bars stack up.

Ever tried smelting elsewhere and felt like you were just feeding a money pit? The Blast Furnace flips that. It requires a bit of setup, sure, but once you’re rolling, it’s smooth sailing. Plus, it’s perfect for that 50 to 70 Smithing hump where other methods drag.

Requirements to Get Started Smelting Mithril

Alright, before you hop worlds and charge in, let’s talk prerequisites. You don’t want to show up empty-handed and get turned away like I did once, forgetting the quest start.

First off, Smithing level 50 is the bare minimum to even touch mithril ore. But trust me, push for 60 if you can. Why? Below 60, you’re paying an extra fee to use the place, and it adds up fast. At 60 or above, that drops, making your runs cheaper.

Quest-wise, you need to kick off “The Giant Dwarf.” Don’t worry, it’s short, just chat with some dwarves in Keldagrim. Takes maybe 10 minutes if you’re quest-savvy.

Gear and items? Ice gloves are non-negotiable. They let you grab hot bars without dousing them first, saving precious seconds and inventory space. I grabbed mine from Heroes’ Quest ages ago, and they’ve paid for themselves a hundred times over. Oh, and the coal bag from the Rogues’ Den? That’s your secret weapon. Holds 27 extra coals, bumping your output way up.

Coins for the coffer: On official worlds, stash 72,000 gold per hour. It’s automatic, 12 coins a tick. If you’re under 60, bump it to 87,000. Small price for the gains.

What about stamina? Bring potions. Running back and forth wears you out quick, and low energy means sloppy mistakes.

Got all that? Good. You’re set to roll.

How to Reach the Blast Furnace Quick

Getting there used to be a trek, but not anymore. I’ve teleported in from the Grand Exchange more times than I can remember, and it’s a breeze.

Fastest way: Minigame teleport to Blast Furnace. Requires starting “The Giant Dwarf,” but boom, you’re there. No fairy rings or carts needed.

From GE? Chat with the dwarf minecart guy on the west side. Costs a few coins, drops you right outside. I use this when I’m banking mid-grind.

Official worlds are 358, 386, or 387. Hop on one, deposit your coffer fee at the chest near the bank, and you’re golden. Avoid busy times if you hate crowds; dwarves man the machines, so no hassle.

Pro tip: If you’re feeling fancy, the skills necklace tele to Fishing Guild, then run west. But honestly, why bother when teleports exist?

Once inside, head down the stairs, past the bank chest. Furnace is straight ahead. Smell that molten metal? You’re home.

Essential Inventory Setup for Mithril Runs

Your inventory is your lifeline here. Mess it up, and you’re wasting trips. Let me walk you through my standard loadout, honed from countless hours.

Start with ice gloves equipped. Always.

In slots: One stamina potion (4) for energy. Maybe a super energy if you’re pushing long sessions. The rest? Mithril ore and coal.

With the coal bag, fill it first: Withdraw 27 coal from bank, stuff the bag. Then grab 26 mithril ore. That’s your first trip maxed.

Why that ratio? Mithril needs two coal per ore at the furnace. So 26 ore means 52 coal total, but bag holds 27, so you supplement with inventory coal on later steps.

Don’t forget a bucket if you’re glove-less, but seriously, get the gloves.

Here’s a quick table to visualize:

Adjust for your level, but this setup nets me 3,500 bars easy. Experiment once you’re comfy.

Step-by-Step Walkthrough for Smelting Mithril Bars

Okay, boots on the ground. You’re at the furnace, inventory loaded. Let’s smelt.

Step 1: Fill the coal bag if it’s empty. Withdraw 27 coal, click the bag. Done.

Step 2: Grab 26 mithril ore from the bank chest. It’s right there, super convenient.

Step 3: Drink stamina if needed, then run to the conveyor belt. Click it, deposit all 26 ore. Watch them rumble in.

Step 4: Now coal time. Empty the bag into the hopper first, then any extra coal from inventory. Aim for at least 52 total coal for those 26 bars.

Step 5: Pedal the pump. Click the marked tile, operate it a few times to heat things up. Dwarves handle the rest on official worlds.

Step 6: While it processes (takes about 6.6 seconds per bar batch), run back to bank. Prep your next load: More ore and coal.

Step 7: Once ready, head to the bar dispenser on the left. With ice gloves, click it direct. Bars pop out, inventory fills.

But wait, don’t collect every trip. That’s inefficient. Here’s my rhythm, the one that got me through 60 to 70 in a weekend.

• Trip 1: Full coal bag + 26 mithril ore. Deposit both.
• Trip 2: Full coal bag + 25 coal in inv. Deposit, then collect first bars.
• Trip 3: Full coal bag + 26 mithril ore. Deposit, collect second set.

Repeat. This cycles two inventories of bars before banking. I once did this for four hours straight, hit 3,600 bars, felt like a machine. But take breaks, yeah?

What if the dispenser’s full? It holds 28 bars. Collect before it overflows, or you’re losing product.

Small tip: Always load coal before ore. Prevents mix-ups with other metals.

Follow this, and you’re golden. Literally.

Maximizing XP and Profit with Pro Tips

So, you’re smelting, but want that edge? I’ve got stories. One time, I forgot my coal bag on a ironman grind. Output halved, frustration doubled. Lesson learned.

First, coal bag is king. Without it, expect half the bars, around 1,800 per hour and 54,000 XP. With it? Skyrockets to 105k+ XP. Buy it cheap from Thieving cape rewards.

Stamina management: Sip potions proactively. Low run energy? You’re clicking slow, rates drop 20%. I pack four pots for two hours, sip every 10 minutes.

World hopping? Skip it unless you’re pinching pennies. Coffer fee is negligible compared to ore costs.

Buy smart: Mithril ore from GE or Ordan in Keldagrim. He’s got stock, often under market. Coal too, but bag helps.

Profit calc: Each bar sells for 803 gp. After 2 coal (say 250gp each) and 1 ore (400gp), net 266gp per bar. Times 3,300? Over 800k minus fees. I banked 500k in three hours last week, funded some Vorkath trips.

XP rates vary by focus. AFK a bit, hit 90k. All-in? 111k. Track with a plugin if you use RuneLite.

Ever wonder about superheat hybrid? Nah, for mithril, pure furnace wins. Magic splits focus.

Oh, and wear varrock armor if you have it. Slight smithing boost, why not?

Common Mistakes and How to Avoid Them

We all screw up. I did plenty. Like that time I logged out mid-load. Lost 50 bars. Ouch.

Big one: Forgetting the coffer. Foreman kicks you out, session ends. Deposit early.

Inventory overflow: Bars hot? Without gloves, you’re splashing water, wasting slots. Get ice gloves, period.

Wrong world: Non-official? You pedal forever. Stick to 358 etc.

Ore-coal ratio off: Too little coal, bars fail. Always double-check deposits.

Low energy: Feels obvious, but I see newbies walking. Stamina pots, people!

Overloading dispenser: Holds 28. Collect on even trips.

Fix these, and your rates soar. Learned the hard way, sharing so you don’t.

Beyond Mithril What to Do with Your Bars

Mithril bars aren’t just XP fodder. Sell ’em on GE for quick cash. Or smith plates, scims, whatever floats your boat.

I smith mith darts for fletching synergy. Or full sets for quests like Myreque.

Table of uses:

Bank extras for later. Never know when a quest calls.

My Personal Grind Stories and Final Thoughts

Man, where do I even start? Back in 2018, I was grinding smithing on my main for that 99 cape. Hit 50, dove into mithril at the furnace. First hour? Botched ratios, made like 1,200 bars. Felt dumb. But by hour three, dialed in, pulling 3k. That 720k profit? Bought my first black d’hide set.

Fast forward to my UIM. No GE, so mining mith south of Ardougne, carting to Keldagrim. Tedious, but rewarding. Hit 70 in two weeks, all self-made. One night, server lagged, lost a load. Ragequit, came back stronger.

Last month, helped a buddy level. He ignored the coal bag. Watched him slog at half rates. “Trust me,” I said. He did, output doubled. Smiles all around.

These grinds build character. The Blast Furnace isn’t just a spot; it’s a rite. Whether you’re chasing 99 or quick gp, mithril here’s your ticket.
