Tim: Thanks for the note and info. I am using C3 and as I said, I've only experienced really bad frosting working with the red dyed candles and some blue/purple. On the days those were poured, I also poured many others and the pouring and room temp was consistent. They were all stored in the same place and several days later, the only ones that frosted were the red. With that said, I understand it may and probably will be back in future pours. However, I found it interesting that these containers now look great after being remelted and poured at cooler temps...they were previously poured at 155F. I also noticed I didn't get the sink holes pouring cooler either. The negative, the additional time waiting for the wax to cool....sure seems like a long time. Might be time to order more pouring pots :smiley2: Brenda
