Thanks TallTayl,
Frosting and graininess can have a lot to do with dye and fragrance, and usually indicate problems in the crystallization process as the product is cooled, generally caused by components in the fragrance oil. Graininess can generally be fixed by adding energy. Get the wax hotter, stir more aggressively, and even pouring hotter can fix this. Freedom wax can generally take it, just be sure not to cool it too quickly, or you could end up with unsightly sink-holes.
A good test to see if the issue is in the wax or fragrance is to microwave several ounces of wax to a temp of 175F, add a couple drops of liquid candle dye (but not fragrance), stir well, and let it cool. If you see heavy frosting (there always seems to be slight frosting in natural soy), it could be a wax issue. Freedom Wax has been formulated to heavily reduce frosting.
Hope this helps!
