Most candle batches need one number: how much oil belongs in the wax you already weighed.

Simple rule

Multiply the wax weight by the fragrance load. Thirty-two ounces of wax at eight percent needs 2.56 ounces of fragrance oil.

• 6% is a cautious start for beeswax blends.
• 8% is a common soy test point.
• 9% to 10% is where many coconut blends land.
