If you notice a white, powdery substance on the surface of your beeswax candle, don't worry - it's not mold or dust. This is called "bloom" and it's a natural process that occurs with pure beeswax. Bloom is caused by the softer oils in the beeswax rising to the surface over time, especially when the candle is exposed to temperature changes. It doesn't affect the performance of the candle and can be easily removed by gently wiping the candle with a soft cloth or heating the surface with a hairdryer.
