What it helps you decide
Plan variants, replicates, cycles, observations, and elapsed testing.
Candle validation
Plan a repeatable burn-test series before approving the candle.
Generate the candle count, burn cycles, observation schedule, and test matrix for wick variants, fragrance variants, replicates, and full-life testing.
Start with the example
The values already filled in are a working example—not a recommendation.
- 1Choose the closest starting point.
- 2Replace the example with your real details.

Your numbers
Test matrix and cycle plan
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Step 1Answer one question at a time. Your example values stay available.
Important limit
A planning journal does not replace applicable candle safety testing.
Test the final vessel, wax, fragrance, dye, wick, fill, cure, and warning configuration through the complete life under controlled conditions. Define stop conditions and follow applicable fire-safety standards and supplier instructions.

How to use the Candle Burn-Test Matrix & Journal
Plan variants, replicates, cycles, observations, and elapsed testing. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Measure the real mold, vessel, fabric, or batch; then use the exact supplier ratio, density, usage ceiling, cure instructions, and expected waste.
Key inputs: Vessel or candle identifier; Wick variants being compared; Wax or fragrance formula variants; Replicate candles per combination; Hours per burn cycle.
How to use the result
Use the estimate to prepare a controlled test quantity. Confirm fit, cure, burn, color, strength, or cut yield before committing a full production run.
