I use what we call paraffin but looks like you call it kerosene.
(y) i'm sure that stuff is available around here... last year i saw a version made from empty jam jars at a friend's place - haven't seen him for a long time so next visit i'm gonna ask him how he made them(iirc he used cooking oil as fuel). empty cartridges sound like a good idea, too but empty .50 cal shells are rather hard to come by in a country which disbanded his military in 1948 (which means no civil war since then and the money gets invested in health care and education instead)
"Lamp Oil" might be another synonym. Used to really stink in hot (40+C) weather.
There's a warmth from carbon flames which will never be matched by modern lights.
thought I'd have a go at making a trench candle today using compression fittings but after some internet research I figured that over here it may not be such a good idea.....
