Calculate wax and fragrance for candle making
Wax Needed
22.46
oz (637g)
Fragrance Oil
1.8 oz
(53 ml)
Total Weight
24.26 oz
For 6 candle(s), excluding containers
Test Your Wicks
Always do a test burn. If the candle tunnels, size up. If it smokes, size down.
Cure Time
Let soy candles cure 1-2 weeks for best scent throw. Paraffin needs less time.
Add Fragrance at Right Temp
Add fragrance at 185°F (85°C) for best scent binding. Stir for 2 minutes.
Inputs
Result
Wax per candle = 8 oz × 0.52 density × 0.90 fill = 3.744 oz. Total for 6 = 22.46 oz. Fragrance = 22.46 × 0.08 = 1.80 oz. Cost = (22.46 × $0.40) + (1.80 × $1.50) + (6 × $0.50) = $14.68.
Inputs
Result
Wax per candle = 4 oz × 0.54 density × 0.90 fill = 1.944 oz. Total for 12 = 23.33 oz. Fragrance = 23.33 × 0.10 = 2.33 oz. Cost = (23.33 × $0.40) + (2.33 × $1.50) + (12 × $0.50) = $15.83.
Multiply your container volume (in oz) by 0.9 (for 90% fill) and then by the wax density (about 0.52 for soy). An 8 oz jar needs approximately 3.7 oz of wax. Always make 10% extra for testing.
Fragrance load is the percentage of fragrance oil relative to wax weight. Most waxes can hold 6-12%. Soy wax typically maxes at 10%, paraffin at 12%. Too much fragrance causes sweating and poor burn.
Wick size depends on container diameter. 2" diameter = CD-6, 2.5" = CD-8, 3" = CD-10. Always test burn - the melt pool should reach container edges in 2-4 hours without smoking.
Soy wax: 135-145°F. Paraffin: 170-180°F. Beeswax: 145-155°F. Coconut: 120-130°F. Pouring too hot causes sinkholes; too cold causes adhesion issues.
Soy candles need 1-2 weeks to cure for best scent throw. Paraffin cures faster (3-5 days). During curing, fragrance molecules bind with wax for stronger cold and hot throw.
