Hello...I just recently tried to emboss on a candle and it is possible....you just have to remember to keep the heat gun moving when heating the embossing powder on the tissue paper the first time so that you don't burn it. When heating the wax paper on the candle the embossing powder remained on the image I wanted it...Hope this helps...it took me a few tries to get it right....I would try it on a cheap candle first and see if it works for you.
