Ok, I received my Excel wax and tested today. I did 4 different size candles, 1.5oz, 3oz, 8oz & 16oz Heated to 190 then poured at 150. All look great, so far no frosting, JUST a sink hole (seen in pic) in the 16oz. Will wait a few days and burn and then let you know what happens. 3oz 1.5oz 8oz 16oz
