About This Tool
Candle Wax & Fragrance Load Sizer calculates exact soy wax flakes and fragrance oil weights in grams and ounces based on candle container capacity, fragrance load percentage, and batch size.
### Candle Making Formulas and Wax Density - **Volumetric Density Correction:** Molten soy wax occupies roughly 86% of the weight of liquid water for the same volume: $$\text{Total Batch Weight (oz)} = \text{Jar Volume (fl oz)} \times \text{Number of Candles} \times 0.86$ - **Fragrance Oil Load:** The fragrance percentage is calculated against the total candle weight: $$\text{Fragrance Weight} = \text{Total Batch Weight} \times \frac{\text{Fragrance Load \%}}{100}$ $$\text{Net Wax Weight} = \text{Total Batch Weight} - \text{Fragrance Weight}$ - **Gram Conversion:** Multiplying ounces by 28.3495 provides precise gram measurements for digital kitchen scales.
### Worked Numeric Example Suppose a chandler pours a batch of 4 candles using 8 fluid ounce glass jars with an 8% fragrance oil load: - **Total Fluid Capacity:** $4 \times 8\text{ fl oz} = 32\text{ fl oz}$. - **Total Wax Batch Weight:** $32 \times 0.86 = 27.52\text{ oz}$ ($780.2\text{ g}$). - **Fragrance Oil Required:** $27.52 \times 0.08 = 2.20\text{ oz}$ ($62.4\text{ g}$, rounds to **$62\text{ g}$**). - **Net Soy Wax Flakes:** $27.52 - 2.20 = 25.32\text{ oz}$ ($717.8\text{ g}$, rounds to **$715\text{ g}$**). - **Per Candle Allocation:** Roughly $179\text{ g}$ wax flakes + $15.6\text{ g}$ fragrance oil per container.
### Client-Side Processing Note All batch measurements evaluate locally in client-side JavaScript. No pouring recipes, fragrance oil ratios, or inventory calculations are sent to external servers.
How to Use
- 1
Enter the liquid water capacity of your candle jar or tin in fluid ounces (e.g. 8 fl oz).
- 2
Select your desired fragrance oil load percentage (standard range is 6% to 10%).
- 3
Input the total count of candles you plan to pour in this production batch.
- 4
Read the net wax flakes weight and fragrance oil weight displayed in grams and ounces.
Frequently Asked Questions
Why does the calculator multiply vessel fluid ounces by 0.86?
Soy and paraffin candle waxes have a specific gravity of approximately 0.86 relative to water. Multiplying water volume by 0.86 accurately determines the true weight of wax needed to fill the container.
What fragrance load percentage should I use for soy wax?
Most standard soy waxes (like Golden Wax 464) hold between 6% and 10% fragrance load without sweating or curdling. 8% (roughly 1.3 oz oil per pound of wax) is the standard industry baseline.
Are any candle recipes or batch figures uploaded to a database?
No. All calculations run strictly in client-side browser memory.
