Candles burn with a higher temperature and there is all the trouble
with the dripping, running wax. Gas jet flames were better. The one
I had, if memory serves, used Calcium Carbide "stones" and by dripping
water on them they would generate acelylene gas. This burns with a
very smokey flame (lots of radiating surface) and a cup of the stuff
(fuel) would last for quite a spell (as they used to say).
Naturally, Union Carbide and Carbon Company made the fuel.
