I made some different size pillars yesterday and everyone turned out with what looks like a hard white film over them all. I could actually take and scrape it off. I am using 1239 wax, I used 2 tbs stearic acid p/p, blue dye and, and 1 oz Blueberry f/o p/p. I poured at 160 into unheated molds. Does anyone know why this could happen? Thanks so much! Marie
