Now, teflon coated cookware might be a different matter - than can give off toxic fumes at high temperatures. Whether you can achieve high enough temperatures on a camp fire, and whether the fumes would be dense enough to cause illness (or death) might be debatable, but teflon (PTFE) can definitely give off extremely poisonous fumes if heated enough.
Really? Has anyone else heard this or does anyone currently use PTFE on fire?
I was thinking of getting a Crusander mug with cooker from eBay, but it's PTFE coated and I'm not sure now.
