Does anyone know how to avoid the major cracking that takes place when using Cargill NatureWax P-1 Soy Pillar Blend? Not only does this wax crack but the candles break in half. I've read other discussions on how "hugging" this wax does not work. Is there a way around this problem or is it simply not good soy wax to use for pillars? Also, is there a soy wax that can be used for making pillars that doesn't crack? Thank you for any input.
