That's exactly what happened to me too when I tried to single wick. Stinks, because you can't wick up since that's the biggest CSN they make. I decided to try and double wick with two CSN 9's and it works perfectly! My jar doesn't get that hot though, like yours does (I use a different jar than you do). If only CS would do their CSN 7's in 6 inch length! Maybe we should request that, I bet that would solve your hot jar problem:2cents: .
