I confess, big_al, I don't have any practice with the search feature. Being an avid lurker I appreciate all the fascinating, often funny, and always instructive posts, though.
I may remember what you are looking for.
IIRC, some ingenious member (apologies for not remembering who) had packed a petroleum jelly soaked cotton ball in a small flat packet made from aluminum foil and said that they got a good long burn time by cutting a small "x" in one side of the foil packet and stretching out a bit of the PJ cotton to create a sort of wick which they lit. I envisioned it as a micro-lamp or a sort of portable pilot light.
Perhaps the folks who passed this on originally will see this and weigh in with their experience...
