We added fragrance to the melted wax at 190ºF. The fragrance incorporated easily, and we didn’t see signs of separation. We tested Cranberry Apple Marmalade from 6% to 12% in all applications and we also tested White Tea at 12% in a metal tart mold with the same results. There were no signs of sweating in our finished candles. For safety reasons, we do not recommend using more than 6% fragrance in pillars, even though the wax can hold 12% fragrance.
Hot and Cold Throw
We tested with Cranberry Apple Marmalade at 6% and 12%. We also created clamshells with a 12% fragrance load. We checked for cold throw performance at 24 hours, 3 days, and one week. Initially, the cold throw was good for all our test candles. After 3 days, the cold throw improved and the cold throw was quite strong. After 1 week the cold throw did not seem any stronger than what we experienced after 3 days.
At the one-week point, we began burn and melt tests. We burned the pillar candles for two hours before examining the hot throw. The pillars rated a strong 2 out of 3 in hot throw performance. We allowed our melts to heat for one hour before examining the hot throw. The hot throw was extremely strong. We recommend using a 9% fragrance load for an optimal throw with wax melts.
