Ever heard of frosting?
I know you've all heard the word frosting before. How does it relate to candles you ask? That's a very good question actually.
Frosting is a natural occurrence that happens with soy wax candles. It usually appears as white crystals on the sides or tops of the candle. Though more visible on colored candles, it can also be seen in white candles. This is totally harmless and does not affect the way a candle burns or smells.
