>>1455764Any single-walled, stainless steel/titanium one will work just fine so long as there's no non-metal gasket or similar thing attached to it. I got some unlabeled stainless steel ones from a thrift store for $1 each. I just bleached the hell out of them and boiled some fresh tomato juice in them 10 times. I made one into the boiler for a water distillery for my rocket stove and the other I just use for general camping use. The gasket is in the plastic lid so I can boil in it and not care. If you have some sturdy wire, make a bail so you can more easily lift it out of a fire or hang it above a fire (pic).
>>1455767Melt them down and make something out of them. Get some stainless ones instead.
