No, I have 7. I never had an issue with any of them. 3 tealight . 2 lang and hello they suck ,the wattage is just too freaking low so they never really get hot enough to throw but you can't beat how cute they are and 2 hot plate ones from tartburners.com Every one smells like crayons man! So now my question is how the heck am I going to make 100 mini slices of cake by Monday with crayola. Dude I don't have time to test new wax! I have been making candles for 6 years and been in business for 4. I found the stuff that worked for me and never strayed, why fix what ain't broke right? I have played with blends in spare time..... but never really had anything that was "better". Plus for this application I need them to be hard, 1 pour and very opaque and have a strong throw. So 4794 and CBL 141 is out for the opaque and one pour thing. Any blending suggestions? Please? Anyone.... Help a sister out?
