There is a natural process called "bloom" that happens to 100% pure beeswax candles. Bloom refers to the whitish cast that takes over the outside of the candle. It does not affect the way a candle burns, and is simply a natural process of the softer oils of the beeswax rising to the outside surface
Why does Candle Bloom Happen?
Bloom is the dull "finish" or sometimes frosty-like "film" that appears on the surface of beeswax, usually when the wax is cold and exposed to air. Bloom is caused by the softer oils in the wax coming to the surface.
Beeswax candles seem to 'bloom' more when the candles have been subjected to many temperature changes. Cold weather tends to cause the candles to bloom more readily
Does Bloom Go away?
The good news is you can always restore the candles back to their original luster if you wish. If you prefer your beeswax candles polished and shiny then just wipe the bloom off with a soft cloth, or slightly warm it up with a blow dryer. It will come back however, possibly in a matter of days. That is the nature of pure natural beeswax
