With soy wax being natural, every candle behaves slightly different when it is made.  A perfect soy wax candle will look soft and creamy, may be sometimes with a subtle  discolorations and unique natural markings on the surface of the candle. This is not a flaw in the candle but a characteristic of soy wax. This in no way affects the burning experience - your candle will still smell amazing and burn beautifully!
