It didn't occur to me that it might be the scents. Duh! I've tried Lovespell, Chanel, White Linen, Cinnamon & Spice, Citrus with Basil, and several others. No, I haven't added anything to the wax. I can try pouring at 180, though, thanks for the suggestion. In the meantime, I've used all 50 pounds of wax and need to order more. Any suggestions on another wax? Is it better to use a straight wax and do the additives myself?
