I'd been playing with blending IGI 2281 & 1284. It's been a couple of months since I've had the chance to work on this. I looked at some of my old notes and with an RRD 29 it was almost completely liquified @ 2hr 15 min - but then smoked. LX 12 was bettter but smoked after 6 hrs. I burned them in the Ice Crystal Trio with a Partylite candle to compare. The Partylite was 1.25 oz and mine was 1.34. I looked at the wicks again and the cotton part of the wick is small but it has a thicker wax coating than the LX or RRD wicks. It is also pure white unlike the CD's or HTP's. Are there any other cotton wicks with that thicker coating?
