I’ve had good HT with a few ultra strong fragrance oils I’ve tested from Northstar Candle Supply. They are formulated for soy and other natural waxes. Problem is, I use wooden wicks. I haven’t gotten the fragrance load right just yet so I’m still testing. Throw has been amazing with these but the wicking is now the challenge. With my regular FO (mostly from Candle Science) I found the HT was much better with patience. With parasoy I can cure for 24-48 hours and get a decent throw when burn testing. With this wax, not so much. I had a friend test some for HT and after shipping they had probably cured for about a week. She said they were amazing!
