Hi! I'm Tracy! I'm having trouble wicking an 8 oz mason jar with Problend 600 wax. I've tried Eco 8 and 10 (both had really tall flames, deep pools w/in a couple ours, and just generally seemed overwicked), LX 16 and 18 (the LX 16 seemed the best, but I noticed some sooting around the top of the jar after about 3 hours of burning), and Premer 760 (seemed underwicked) and 765 (seemed overwicked). I'm completely lost. Any suggestions?
