I know this is an old thread, but it relates to my current question. Where do you buy the polyeurathane spray, and is it non-flammable? I am very concerned about safety. I'm still practicing candlemaking, but want to plan ahead for labels and need to practice on those also (since I've never made any before). I would like to use 4x5 size on some of my jars. I might also want to use this size in the clear plastic labels, but don't want to have them melting when the candle gets hot. I want a label which I can print vibrant colors on, though, so the white paper-type labels (such as the Avery type) might be better, but I want a glossy finish on the labels. I'm assuming the white paper-type labels are non-flammable, since its seems that lots of candlemakers are using this type. Am I correct in this assumption? Any advice will be appreciated
