A SMALL TOOL WITH ONE JOB
About Pourmass.
Pourmass estimates the material mass needed to fill a number of equal vessels.
It accepts a measured usable volume or a straight cylindrical or rectangular inside shape. Your supplied density connects that volume to mass. An optional reserve adds a stated percentage of required fill mass to the batch total.
This is a mass-planning tool, not a candle formulation. It does not divide a mixture into ingredients, specify temperatures, choose wicks or establish vessel suitability.
Free to use
There is no subscription, checkout or account. The calculator is part of an independently operated collection of free planning tools. Each site focuses on one calculation so its assumptions stay easy to inspect.
How the tool is maintained
The calculation method is described in the worked guide. Automated checks cover conversion factors, example results and invalid inputs. A model can still miss a practical detail; use the guide to decide whether its assumptions fit your situation.
