LOL, mine so far have been all from scents. I once ran out of fragrance oil and decided to try some oil I had for this oil burner. Obviously the product was not supposed to be around a flame when 1/2 hour into the candle burn it "exploded" into flames. I can say my hubby NEVER questions my desire to by my higher quality fragrance oils now!! And when I first started messing with making candles, shoot, I just dumped several ounces of fragrance oil into some wax. Wouldn't be bad if it would've been alot of wax, but it wasn't. It "sweated" oil for about a year!!!
