Great idea, but be careful. If not designed to be heated, some ceramic materials are frangible under localized heat and subject to spalling. These could forcebly expel a sharp piece of surface material into your face due to uneven expansion.


That said, I would be interested in seeing how 'found' fuels compare:. A burn time and smoke comparison with a similar wick (a small strip of cotton sock for example) between equal amounts of:

various cooking oils
oil from a tuna can
oil from a piece of beef fat
crisco shortening
margerine
parrafin wax
motor oil

Probably should do outdoors.....
