Hello! So I am trying to make candles for sale and am having issues with how they turn out. I am using paraffin wax that has a melting point of 126. I usually get it heated to around 130-150. At that point I put in the color blocks and mix and then take off the heat and mix in the fragrance oil. In addition to this, I heat the mason jars in the oven to prevent air bubbles and/or sinking in the middle of the candle. However, once the candles have cooled off for over 24 hours, there is discoloration and hundreds of bubbles throughout the candle. I will attach a photo to help illustrate this issue. Any advice on what could be causing this? I have made 6+ candles and having the same issue.
