I've really been trying to "keep it natural" but it seems like the only practical way to do this is to keep it white.... boring. Are there ANY suggestsions? Does putting powdered herbs/spices affect the burning of the candle? I've looked into minerals used to dying soaps, but this seems just as hazardous, if not more hazardous as normal dyes. I'm a biologist, and although my knowledge in toxicology dosen't rival an expert, I know it's theoretically possible for the minerals to turn into fumes... Lead Oxide might turn into lead fume... this isn't any good. Any suggestions on synthetic dyes (which ones from where are best?)? I was considering the super strength ones from Candlewic... has anyone had any expierience with these? Just how strong are they? How have the rest of you guys dealt w/ colorants in your pursuit of an all natural candle?
