Type of wax = EZ Parasoy Fragrance load = 10% Type of warmer = Halogen, Glade Hot Plate, and Bulb Warmer (not sure of wattage) Works best in the Glade hot plate and the Bulb warmer, Halogen gets too hot (even when turned down) although if I use less wax (ie: 1 square of six cavity clamshell vs 2 squares) I get better results in the Halogen. I get 10-15 hours of good to great throw out of 2 squares of a six cavity clamshell. All 330 of my fragrances have been tested by 35 outside independent testers.
