I'm testing CD10, CD12, and Premier Wick WI 767 (from candlemaking.com) with 4630, no coloring, 1oz per lb of FO in 8oz square mason jars. And the CD's dance around alot and puff smoke occasionally while the 767 has a much tamer flame. It has a good melt pool, going all the way across in about 2 hours and after 4 hours was maybe 1/2" deep. I'm liking this wick! But not sure about the HT. Going to try it with 1.5oz of FO.
