Pure Soy Wax candles have a high tendency to “frost” – this is when small white crystals on the sides or top of the candle start to form and this is especially apparent when adding dyes. One possible reason for this is that you're pouring the wax when it is too hot or cool – try to pour at the right temperature – at around 36 to 43 degrees Celsius. Another reason could be your room temperature – if it is too cold, your wax will be cooling too quickly resulting in your candle to start frosting. We would also advise you to mix your wax gently and not too vigorously as well as cooling on a wire rack. Do remember that frosting is extremely common with 100% Soy Wax and indeed, many candle 'experts' even look for the frosting as proof as it is an actual pure Soy Candle!
