i am sure this has been covered a gazillion times but what metals (cups, nalgenes) can be used over open flame without a bad ending? (bad flavor, chems, etc). thinking more of cups that can be used for hot coffee, tea in the field.
i know aluminum and titanium and i know do not do any of this if the inside of the cup is covered with a plastic lining or what not. some tips, pics etc would be greatful
