I thought I had this soy thing down!! Nice smooth tops, good scent throw, and no frosting (so I thought). So I started selling my candles. I have some that have been sitting in my house for a month and when I opened up the tin, there it was a white ring around the edge of my wax. AAHH!!! I use cb135, no additives, 6-7% fragrance, no dye. The stuff looks like old chocolate now. How do you stop this?? I have read this forum and others and don't know what to do to give the candles shelf life. I am not willing to add paraffin so that one is out. Any help would be much appreciated. Thanks
