I am using a 50/50 mix of GB 464 with IGI 4627. (Gave up on all soy). Apart from the 4627 being like a big blob of vaseline, I really like this combo. Poured beautifully, nice burn, etc. I decided to go for it, and put 2oz per lb of FO, which is the max for both of these waxes. I'm using an ECO 10 wick, in an 8oz square mason jar, which is working well, but around hour 3, the flame gets big, and it starts to soot. I don't think I could go any smaller without tunneling. So, my question is, should I seek out a different wick, or is it more likely that I've gone too gung-ho with the FO, and should cut back to the standard 1oz/lb? I have some other wicks on hand, so I'd take wick suggestions, too. Thanks!
