Please note that over time, your black candles may develop frosting, which is a natural occurrence in vegetable waxes, hence our Signature color “COAL BLACK”.
This will create a stone-like effect on the surface of the candle. This happens because the wax is reverting to its natural state and starts to crystallize.
However, it is important to note that frosting does not affect the candle's functionality in any way. In fact, it indicates that the wax used is completely natural.
