What it helps you decide
Plan variants, replicates, cycles, observations, and elapsed testing.
Candle validation
Generate the candle count, burn cycles, observation schedule, and test matrix for wick variants, fragrance variants, replicates, and full-life testing.
The values already filled in are a working example—not a recommendation.
Your numbers
Use the filled example first. Then replace each field with a measured value or your best current estimate.
Important limit
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.
About this free craft materials & fabrication tool
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.
Plan variants, replicates, cycles, observations, and elapsed testing.
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.
Use the estimate to prepare a controlled test quantity. Confirm fit, cure, burn, color, strength, or cut yield before committing a full production run.
Excel spreadsheet export
Use the Candle Burn-Test Matrix & Journal in your browser, then export a branded .xlsx materials worksheet to save material measurements, supplier assumptions, and the quantity planned for the project.
This gives you a portable materials worksheet you can save with an order, production record, planning meeting, or pricing review. The workbook keeps the source link and date with the numbers, making it easier to understand where the result came from when you reopen or share it later.
Spreadsheet questions
Use the browser calculator for speed, then take the result into the spreadsheet workflow that fits your business.
Yes. Enter your information, review the live result, and select Export to Excel. Batch Scale creates a branded .xlsx workbook with your inputs and the result shown by the tool.
The workbook includes a Tool Result sheet, an Inputs sheet, the original calculator link, and the date generated. When a supported calculator has an Excel formula profile, its result cells remain connected to the editable input cells.
You can import the .xlsx workbook into Google Sheets. Because spreadsheet applications sometimes interpret formulas and formatting differently, confirm any important result after importing—especially before using it for pricing, safety, compliance, or production.
Yes. The calculator and workbook are free. The first Excel export on a device asks for your email and permission to receive occasional practical Batch Scale resources. Once captured, later tool exports on that device download directly.
