Please do not place your fancy enamel cast iron pots and pans over a campfire. The only pots and pans that can go directly over a campfire or hot coals are cast iron. For Dutch ovens, look for pots that have little feet so that it can sit above the hot coals and air can circulate. For lids, make sure yours has a lip around it as you put hot coals on top and you don't wash ash to trickle into your food when you life the lid.
