Color variations in soy candles are normal and referred to as frosting.  Frosting is when the soy wax forms tiny, white, frosted-looking crystals on the top of the wax and/or on the sides of the jar.  It looks very similar to the white frosted look that sometimes appears on chocolate.  I am committed to providing you with paraffin-free candles and therefore do not add paraffin to my wax.  I have experimented with my dyes, fragrance oils, and pour temperatures to keep frosting to a minimum, but some frosting may occur so if you notice this, it is to be expected with all soy candles and will not affect the fragrance.
