I added 7 oz of Crisco to 3 lbs of 464, 8% fo, poured at 135 and got ugly tops, great color and no frosting. I used the heat gun and the tops are still like cottage cheese. I will let them set a few days and burn. Next day the frosting reappeared. I also added 7oz of mineral oil to 3lbs of 464, same results, ugly tops, can't smooth them out with a heat gun. I will try cutting down on the Crisco, just to cut the frosting, and forget the mineral oil. Just a last note to anyone considering this. At one week the Crisco candles started to sweat, this is not good for me. The straight 464 candles did not sweat.
