I have had some luck retoning copper on the stove heating element-at low heat. I may add that I have done this for otherwise cleaned and ruined coins, I hasten to add, just to see how it looks. It may take some time at low heat, try it for 20 minutes, then 40, then an hour and monitor the progress. Perhaps take the foil off?
