Does it work?
I've yet to try it out.
I'm thinking that one could use copper wire to make a pot structure (weave or more primitive) and then cover it with tin foil (from the inside, so that the water would effectively hold it in place). It should be watertight and resistant to heat, no?
Would the copper melt or the tin foil warp (I think the aluminium melts at over 2000 degrees or something, so I would stick to smaller fires )?
Also, would there be any problems with the copper or tinfoil emitting nasty stuff into the water or would it be safe to drink afterwards?
I had a search but could find nothing. Cheers for any pointers or replies. Pics very welcome, I like to visualise things
