I have found an old size #10 dutch oven, with deep sides. It is rusted, has the short legs on the bottom for using on a camp fire, and has a raised ring around the lid for the hot coals to stay on top with out falling off. I've always wanted to cook a peach cobler, and bake biscuits in one. The inside is rusty looking, but not knowing the history of where it has been, and if was indeed used for cooking. QUESTION: Do you think if I just put it on a fire, got it hot, used a wire brush to remove the rust, then oiled it, it would be okay to use? There is a test kit I can buy to see if any lead is present. Anybody have any thoughts?
