I've only been experimenting with candle making for about 2 months now, and I feel like I must be missing something. My understanding is that the wax pool should expand to the edge of the jar rather than leaving unmelted wax around the sides and "tuneling." My problem is that when I use a wick large enough to create a full melt pool, I'm left with this odd, not very attractive, residue on the side of my jars. I haven't seen this happen with soy candles that I purchase. I am using 464 with 6% FO, and I've effectively eliminated FO as the issue here, since I've had the same thing happen with other FO's and unscented candles. I am warming the jars prior to pouring and I don't think pour temp is the problem either, since I've tried pouring at various temps. Would GREATLY appreciate any insight!
