'Frosting' (1) is a common problem when working with soy wax! Frosting is the formation of white spots (sometimes pretty large ones) that make appear your candle less nice or perfect.
Frosting bothers most of the people approaching soy wax, but I want to remind you that this 'phenomenon' (to me it's not a flaw!) occurs when you use pure soy wax and it is therefore indication of a 100% soy wax candle!!!
Here you have some suggestions to reduce frosting:
- pre-heat the container
- stir the melted wax not too vigorously
- pour the soy wax at the coolest temperature possible (I do agree that this helps a lot)
- use additives
If you're still having frosting problems despite all these tricks, I'd advice you to either use a non-transparent container (tin containers or opaque glass containers) or to DECORATE your container so that you can hide the excessive frosting!!!
You can recycle left overs of sewing/embroidering (2) and create a nice decoration with the help of a glue gun (3).
