I have poured several candles with Millennium Wax and while the sides look great in glass, the tops... ALL of them ended up crusting up with frosting or crusting underneath. I have followed directions carefully. It said to stir down to 115 - I have a magnetic stirrer which can go quite slowly as to avoid adding air. I can't seem to make this work. I have better luck with the Production Single Pour container wax from Candles and Supplies (not a plug, just for reference. I'm happy for someone to point out what I'm doing wrong with it.
