Candle Making
Free candle making calculators and reference guides: wax amounts, fragrance load, wick sizing, cure times, pouring temperatures, burn time and pricing.
Candle making runs on a handful of numbers: how much wax a container holds, how much fragrance oil the wax will take, which wick suits the diameter, and how long the wax needs to cure. The calculators below work those out for a specific batch. The guides cover the reference ranges behind them, wax type by wax type.
Wax melts use the same waxes and fragrance oils, so their calculators live here too.
