Definition: As beeswax ages, often a white, powdery substance will appear on the surface. Don't fret, it's not mildew, it's called "bloom" and it's actually a completely natural occurrence and a sign that your beeswax is really pure. It doesn't affect the quality of the candle or the burning of the candle, and most people just leave it alone, feeling that the "bloom" gives the candles an antique or textured appearance. If you want to though, you can just wipe it off gently with a dry cloth, or remove it by heating the candle lightly with a hair dryer.
