Sometimes during the manufacturing process, extra air and/or moisture can get incorporated into your wax. This is completely normal and will not affect your finished candles. It will usually correct itself as the wax melts and releases air and moisture - that’s the cloudiness and popping you are seeing and hearing. You may notice as your wax reaches temperature (185° F), the cloudiness will start to clear up. Sometimes you can stir gently to help release the air. If your wax is still cloudy once it reaches 185°F, you can hold it at that temperature for a longer period of time to allow the wax to continue to clear before you add your fragrance and pour your candles.
