I know what you mean about testing. It's not a easy job to do. I hate this happened to you right at the holidays. I posted some pictures in another thread with one picture of my layer candles. My bestsellers are my layers whether it's two, three, four, or five layer candles. I'm not sure if you seem my pictures or not but you can get an idea of how this wax works with layers. I use "Joy Wax". Good luck. http://www.candletech.com/forums/showthread.php?t=37833
