Definetley, especially as it's opposite of what other people have found!
sargey said:have you used a commercial trangia at all?
Yep, and when stoves I've made have worked just as well as atrangia (at least the ones without fiberglass!

It's a while since I made them so I'll have to make some more and actually do a direct comparison. It was probably something wrong with my construction.
sargey said:what should happen is that the burner heats up to the stage that the meths boils, the vapour given off then burns hotter/faster than just the meths. if the meths is all sucked up inside the walls it comes out of the holes in the top of the stove doing a viable impression of a gas burner. with a load of blue flames. if not you just get the one big flame inthe middle.
Yeah both types do this, but the fiberglass ones I've made haven't done as good impression of a gas burner as one's without.
