How to Make Your Own Cannonballs at the Blast Furnace in OSRS

The Blast Furnace in Old School RuneScape (OSRS) is a popular location for players looking to smelt their ores efficiently. Unlike traditional furnaces, the Blast Furnace allows for smelting multiple ores at once, making it an ideal spot for crafting items like cannonballs. This guide will help you understand the basics of using the Blast Furnace and the specific requirements needed to create your own cannonballs, enhancing your gameplay and combat capabilities.

To successfully make cannonballs at the Blast Furnace in OSRS, players must meet several requirements and gather specific materials. First, you will need a minimum level of 35 Smithing to create cannonballs, as it is a prerequisite for using the furnace effectively. Additionally, players should have access to the Blast Furnace, which is located in Keldagrim.

The primary materials needed to make cannonballs are steel bars, which are produced by smelting iron and coal. Specifically, you will need one iron ore and two coal ores to create a steel bar. It’s worth noting that you can also purchase steel bars from other players or the Grand Exchange if you prefer not to mine and smelt them yourself.

Once you have your steel bars, head to the Blast Furnace. To use the furnace, you will need to pay a fee of 250 coins, which can be done by speaking to the foreman located near the entrance. This fee is a small price to pay for the efficiency and speed of the Blast Furnace.

In addition to the steel bars, it is essential to have a hammer in your inventory, as this tool is required to forge the cannonballs from the bars. After paying the fee and having the necessary items, you can use the steel bars on the furnace to begin crafting cannonballs. You will receive 4 cannonballs for each steel bar you melt, significantly increasing your ammunition supply for ranged combat.

It’s also important to note that you can use the Blast Furnace with other players, which can speed up the process further. Collaborating with friends or fellow players can help you share the costs and resources, making the entire experience more efficient. Overall, by fulfilling these requirements and gathering the necessary materials, you’ll be well-equipped to craft your own cannonballs at the Blast Furnace in OSRS.

5. Tips for Efficient Cannonball Production

Making cannonballs at the Blast Furnace can be a rewarding experience, especially if you’re looking to level up your Smithing skill efficiently. Here are some tips to help you maximize your cannonball production:

Use a Blast Furnace: Always use the Blast Furnace instead of traditional forges. The Blast Furnace allows you to produce cannonballs much faster and with less coal.
Bring the Right Supplies: Ensure you have a good supply of both steel bars and coal. For every cannonball you make, you’ll need one steel bar and four pieces of coal.
Utilize the Dwarven Multicannon: If you have a Dwarven Multicannon, use it near the Blast Furnace to defend against aggressive monsters while you work. This way, you can focus on crafting without interruptions.
Join a Team: Consider working with friends or other players. Teaming up can help you gather materials faster and share the workload.
Use the Right Gear: Equip gear that increases your Smithing efficiency. For example, wearing the Varrock Armor can grant you a chance to smelt an extra bar when using the Blast Furnace.
Take Breaks: Don’t forget to take breaks! Staying focused is great, but your efficiency can drop if you’re feeling fatigued.

By following these tips, you’ll find that your cannonball production becomes smoother and more efficient, allowing you to create ample supplies for your adventures in Gielinor.

6. Common Mistakes to Avoid

While making cannonballs at the Blast Furnace can be straightforward, players often fall into traps that hinder their efficiency. Here are some common mistakes to watch out for:

Overlooking Coal Requirements: One of the biggest mistakes is not bringing enough coal. Remember, you need four pieces of coal for each cannonball you produce. Always check your supply before starting.
Ignoring Blast Furnace Mechanics: Familiarize yourself with how the Blast Furnace works. Not using the conveyor belt effectively can lead to wasted time and materials.
Not Paying Attention to Health: If you’re in a PvP area or near aggressive monsters, make sure you monitor your health. Dying can result in losing your materials and time.
Not Using the Right Tools: Ensure you have a hammer in your inventory. Without it, you won’t be able to create cannonballs, which can lead to frustration.
Failing to Use Boosts: Don’t forget about potions or food that can boost your Smithing skill temporarily. These can make a significant difference in your production rates.
Neglecting Inventory Space: Always check that you have enough inventory space before you begin. Running out of space can interrupt the process and cost you valuable time.

By avoiding these common pitfalls, you’ll enhance your cannonball production experience and make the most of your time at the Blast Furnace.

7. Profitability of Making Cannonballs

Making cannonballs at the Blast Furnace in Old School RuneScape (OSRS) can be a lucrative endeavor, especially for players looking to supplement their income or train their Smithing skill. Let’s dive into the details of how profitable this activity can be.

First off, the cost of materials plays a significant role in determining profitability. To make cannonballs, you need:

Steel Bars: Each cannonball requires one steel bar.
Blast Furnace Fee: There’s a small fee for using the Blast Furnace, which is 1,000 coins per hour.

Now, let’s break down the numbers:

Item	Cost	Profit per Cannonball
Steel Bar	Approx. 1,000 coins	Approx. 200 coins

Given that each steel bar produces 4 cannonballs, here’s how the math works:

Cost to make 4 cannonballs: 1,000 coins.
Selling price for 4 cannonballs: Approximately 1,200 coins.
Profit: 1,200 – 1,000 = 200 coins.

When you consider that you can create around 1,000 cannonballs per hour, your profits can quickly add up. This makes the endeavor not only profitable but also a great way to level up your Smithing skill while earning some extra gold!
