My, what an old thread.
What did adding carnauba wax do to the flow? Do you know what your final recipe was? This is relevant to my interests!
Also, what kind of surfactant do you use?
Lastly, maybe your wax-sticking problem was due to a thin, invisible film of wax stuck to the inside of the globe. This would prevent your surfactant from doing its job keeping the glass and wax separate. When I had that problem, I had to scrub the inside of the globe out with a scrub brush and some abrasive cleaner. I used Bon Ami and it seemed to get all the wax off without scratching the glass. Oh, and NEVER DO THIS:
hmmmm...try waxing the inside of the globe w/carnabuayowe stuff first..couldn't hurt!
good luck an woooops if it gets WORSE! <--disclaimer
