Rough, Pitted Tops After Burning
The rough, bumpy tops after burning a soy wax candle are caused when the hot wax in the melt pool cools and solidifies at an inconsistent rate. This is a feature of soy wax, and not a sign you did anything incorrectly.
In fact, you can even use this feature as a way to show the candle is made with an all-natural soy wax. It does not affect the performance of the candle. If you find you simply do not like the look of a soy candle post-burn, we recommend using a blended natural and paraffin wax like IGI 6006.
