Mastering OSRS Blast Furnace in 2025: How Botting Hub’s Scripts Turn Smelting into Passive Gold
OSRS Blast Furnace is widely known as one of the most profitable and efficient methods to train Smithing in Old School RuneScape — but let’s face it: doing it manually is a full-time job. With a constant need for stamina, tight tick-perfect inputs, and multiple item movements, it’s one of the most demanding pieces of content in the game.
But here’s the good news: Botting Hub has automated it all.
With the right setup — high Agility for the Graceful outfit and a Coal Bag for better inventory efficiency — you can run a Blast Furnace bot for millions of GP per day, hands-free.
In this guide, we’ll cover:
Why OSRS Blast Furnace is the ultimate goldfarm
The best pre-requisites: Graceful set and Coal Bag
How Botting Hub’s AI scripts handle everything
Profit potential per hour (estimates)
Safe botting strategies for 2025
Let’s get into it.
Why OSRS Blast Furnace Is the Goldfarming King in 2025
OSRS Blast Furnace is a group-based minigame that allows players to smelt bars using half the usual amount of coal, massively increasing both speed and profit.
Key benefits:
🔥 Huge profits: up to 1.5–2.5M GP/hour
⏱ Fast XP for Smithing (especially Gold bars with Ice gloves)
🧍 Can be done on one account or scaled to multiple bots
🧠 Predictable and repetitive = ideal for botting
However, to truly unlock its potential, you need two key upgrades:
Step 1: Unlock Graceful with Botting Hub’s Agility Script
Running around the Blast Furnace takes stamina. Without Graceful gear, your bots will waste energy, slow down, and make fewer bars per hour — reducing your GP yield.
That’s why the smart move is to bot Agility first, using Botting Hub’s Agility Script, which:
🏃 Automatically runs rooftop courses from 1–99
📦 Collects Marks of Grace to get the full Graceful outfit
🔁 Uses human-like movement and break timers for low ban risk
With Graceful, your bots use 30% less run energy — directly improving bar output per hour.
Step 2: Unlock the Coal Bag with the Motherlode Mine Script
The Coal Bag is another must-have. It allows your bot to carry 27 extra coal, reducing trips and maximizing furnace uptime.
Use Botting Hub’s Motherlode Mine script to:
⛏ Safely mine pay-dirt at the Motherlode Mine
💰 Earn golden nuggets to purchase the Coal Bag
⚙️ Automate every part of the grind — no clicking required
These two upgrades (Graceful + Coal Bag) make your bots 30–50% more efficient.
How Botting Hub’s AI Blast Furnace Script Works
The AI Blast Furnace bot is not just another script — it’s a smart automation tool powered by machine learning and behavioral modeling.
🔍 Core Features:
Adaptive Movement: Realistic cursor paths, shift-dropping, inventory management
Tick-Optimized Logic: Minimized delays without being suspicious
Stamina Pot Usage: Auto-drinks when needed, detects low run energy
Coal Bag Support: Automatically fills and empties the bag for max coal efficiency
World Hopping + AFK Detection: Avoids crowded worlds and gets unstuck fast
Whether you’re making Steel Bars for bulk GP or smelting Gold Bars with Ice gloves for XP, this script does the work for you — intelligently.

Botting Smart: How to Stay Safe in 2025
Like all high-reward botting methods, Blast Furnace has some risk — but Botting Hub makes it far safer with true AI-driven behavior.
✅ Use fresh accounts with some questing & stats
✅ Limit usage to 4–6 hours/day with random breaks
✅ Mute public chat and world-hop if crowded
✅ Use residential proxies to separate accounts
✅ Regularly mule gold to avoid major losses
Botting Hub’s Break Manager, Mouse Movement Engine, and Failsafe System are all designed to mimic human behavior and reduce detection.
TL;DR: Automate Smithing, Print GP
If you’re serious about goldfarming or just want to hit 85+ Smithing without sweating over coal runs, Blast Furnace is the move — and Botting Hub gives you the ultimate toolkit to master it.
By first unlocking the Graceful set with BH Agility and the Coal Bag with BH MLM, your bots can operate with max efficiency and minimal downtime.
