I'm having a problem with my incense sticks staying lit. I use 1 part FO to 2 parts DPG. Soak them for 24 hours and dry for 72+. Almost each and every one that I light will burn out after a minute or two, sometimes even less. I've tried keeping the flame burning for a few seconds longer than I normally would before blowing it out but even that doesn't work. I've even let the sticks dry out for over a week and they still go out. What am I doing wrong? Thanks in advance Jon
