How to use the Candle Fragrance Load Calculator
Plan wax and fragrance per vessel and master batch. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Start with a tested baseline formula, measured weights, the unit used by the full batch, and your actual finished yield or process loss.
How to use the result
Treat the output as a controlled batch draft. Record the assumptions, run a small test, and approve the result only after checking quality and safety.
