What is the Superglass Make Spell?
Superglass Make is a high-level utility spell from the Lunar spellbook in Old School RuneScape, requiring 77 Magic to cast. Its primary function is to convert sand and a seaweed-based item (regular seaweed, giant seaweed, or soda ash) into molten glass without a furnace. This spell is a cornerstone of efficient Crafting training, especially for ironman accounts. A proficient player using this spell can achieve excellent experience rates and, with the right market conditions, significant profit. The efficiency of this method is why a dedicated superglass make calculator is an essential tool for any serious skiller.
Who Should Use This Method?
This method is ideal for players looking to train their Crafting skill quickly. It’s particularly popular among ironman accounts who need to gather all their own resources, as it provides a much higher yield of molten glass per raw material compared to a furnace. Main accounts can also find it highly profitable, turning raw materials into a valuable secondary resource. Using a superglass make calculator helps these players maximize their hourly profit by inputting real-time Grand Exchange prices.
Common Misconceptions
A common misunderstanding is that you need to cook Giant Seaweed into soda ash first; the spell works directly on the seaweed. Another point of confusion is the yield. The spell doesn’t produce a fixed amount of glass; it’s a variable amount that averages out over many casts. The most efficient method (3 Giant Seaweed and 18 Sand) yields an average of 1.6 glass per bucket of sand, a fact that is central to any accurate superglass make calculator.
Superglass Make Calculator Formula and Explanation
The calculations behind this superglass make calculator are based on established averages for the most efficient inventory setup: 3 Giant Seaweed and 18 Buckets of Sand. Here’s a step-by-step breakdown of the logic used.
- Determine Number of Casts: The number of casts is dictated by the ratio of resources. Since one cast consumes 3 Giant Seaweed, the total number of casts is `Total Giant Seaweed / 3`.
- Calculate Total Sand Needed: Each cast uses 18 Buckets of Sand. So, `Total Sand = Number of Casts * 18`.
- Calculate Molten Glass Yield: On average, each Giant Seaweed yields 9.6 Molten Glass when using this method. `Total Molten Glass = Total Giant Seaweed * 9.6`.
- Calculate Total Costs: This is the sum of all materials: `(Giant Seaweed Amount * Seaweed Cost) + (Total Sand * Sand Cost) + (Number of Casts * Rune Costs)`.
- Calculate Total Revenue: This is simply `Total Molten Glass * Molten Glass Price`.
- Calculate Total Profit: `Total Profit = Total Revenue – Total Cost`. For more details on profit, check out our OSRS Money Making guide.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Giant Seaweed | Primary ingredient for glass production. | Items | 100 – 10,000+ |
| Buckets of Sand | Secondary ingredient, required at a 6:1 ratio. | Items | 600 – 60,000+ |
| Astral Rune Cost | GP cost for the runes needed to cast the spell. | GP | 100 – 300 |
| Molten Glass Price | The market selling price of the final product. | GP | 150 – 300 |
Practical Examples
Example 1: A Standard Profit Run
A player has bought 3,000 Giant Seaweed and wants to calculate their profit. They input the following into the superglass make calculator:
- Giant Seaweed Amount: 3,000
- Giant Seaweed Cost: 1,100 GP each
- Bucket of Sand Cost: 180 GP each
- Astral Rune Cost: 160 GP each
- Fire/Air Rune Cost: 0 GP (using staves)
- Molten Glass Price: 220 GP each
The calculator determines: 1,000 casts are needed, consuming 18,000 sand. Total cost is 6,700,000 GP. The yield is 28,800 molten glass, for a revenue of 6,336,000 GP. The result is a net loss of 364,000 GP, but a massive gain in Crafting experience. This highlights how the superglass make calculator is vital for assessing profitability versus XP gain.
Example 2: An Ironman’s XP Goal
An ironman has farmed 500 Giant Seaweed and mined their own sand. They want to see the XP output. They use the superglass make calculator with cost inputs set to 0.
- Giant Seaweed Amount: 500
- All Costs: 0 GP (self-sourced)
- Molten Glass Price: 210 GP (for value tracking)
The calculator shows they will perform ~166 casts, yielding 4,800 molten glass. The total value of this glass is 1,008,000 GP. More importantly, they will gain 30,000 Crafting XP and 12,948 Magic XP, information crucial for planning their skilling progression. For more on this, see our Ironman Skilling Methods page.

Key Factors That Affect Superglass Make Results
The profitability and efficiency of using Superglass Make can swing dramatically based on several factors. A good superglass make calculator allows you to model these variables.
1. Molten Glass Price
This is the single most significant factor for profit. Molten glass prices fluctuate with supply and demand, often tied to players training Crafting by blowing glass. A small 10 GP change per piece can alter your total profit by hundreds of thousands.
2. Giant Seaweed Cost
As the primary limiting ingredient, the cost of Giant Seaweed is critical. Prices can be volatile. Players who farm their own via Giant Seaweed Farming have a massive cost advantage.
3. Bucket of Sand Cost
While less expensive than seaweed, you need six times as many buckets of sand. Buying sand directly from the Grand Exchange is convenient but adds up. Many players opt to mine sandstone in the desert to process into sand for free.
4. Astral Rune Price
You need two Astral Runes per cast. While not a huge cost individually, over thousands of casts for a big Crafting grind, this cost becomes substantial. A high Astral Rune price can eat into your margins.
5. Use of Elemental Staves
The spell requires 6 Fire and 10 Air runes per cast. Equipping a Fire Battlestaff (or equivalent) makes Fire Runes free. This is a simple but effective way to cut costs and is a standard assumption in any serious superglass make calculator.
6. Clicks Per Hour (Action Speed)
While not a variable in the calculator, your personal speed at banking and casting directly impacts your XP and profit per hour. Efficient players can perform over 1,000 casts per hour, maximizing their gains far beyond slower players.
Frequently Asked Questions (FAQ)
No, this calculator is optimized for Giant Seaweed and the 3:18 inventory ratio, which is vastly more efficient. Regular seaweed provides a much lower yield and is not recommended for serious training.
Extensive testing by the OSRS community has shown that when using 3 Giant Seaweed and 18 Buckets of Sand, the spell yields an average of 1.6 molten glass per sand bucket (or 9.6 per giant seaweed) over a large number of casts. This is the accepted standard for an accurate superglass make calculator.
For maximum XP and profit per hour, most guides recommend NOT picking up the glass that drops. The time spent looting is better spent starting the next cast. This calculator assumes you get the full yield, which may require picking up glass, but for efficiency’s sake, many players accept a slightly lower yield for faster casts.
Absolutely. Simply set the cost fields for any materials you gathered yourself (seaweed, sand, runes) to 0. This will show you the total value of the glass you produce and the net profit from selling it, which is useful for cash flow planning.
Yes. You get 60 Crafting XP for each Giant Seaweed consumed and 78 Magic XP per cast. This tool calculates the total Magic XP. Crafting XP is a direct multiple of your seaweed input (Your Seaweed * 60).
You must complete the Lunar Diplomacy quest to access the Lunar spellbook. This is a hard requirement before you can even consider using this method or a superglass make calculator.
Any bank is suitable, but a bank with a small footprint, like the one at Ferox Enclave, is often preferred for minimizing mouse movement and maximizing casts per hour.
Yes, a Smoke Battlestaff provides unlimited Air and Fire runes, covering two of the three rune types needed for the spell. This is a great cost-saving measure for anyone doing this method at scale.
