Toxins in Candles: Sad, But True - Keeper of the Home. buy/make ONLY beeswax or soy candles and avoid metal in the wick (could be lead). Actually, I just read all the comments. Beeswax isn't necessarily pure (doy, why are all the bees dying) and soy....well, nope. I think I'm going to have to give up candles and buy more tuberose and quince when it is in season.
