What is the dusty substance of the surface of many beeswax candles?
The dusty looking substance on the surface of the candles in this picture is called “bloom”. It is a naturally occuring substance on all beeswax candles after they have been aged for a period of time. It is desired by many people as it gives the candle a very “antique” look and only beeswax will develop it. If desired, it may be rubbed off with a soft cloth.
