XenoMuseNo. Its supposedly dangerous to cook in because it could flake off and infect food or could chemically alter the food itself, kinda like how/why caterers use plastic wrap underneath the aluminum foil in a hotel pan to help prevent such a thing as red pasta sauce from doing just that.
to answer your question above, all I cook in and on is a cast iron, aluminum pots for stock, stainless steel or coated ’ss’, some baking pans with silcon steel I believe, or flat out glassware.
FiendmakerThe copper stuff is usually tin plated to prevent chemical interactions of food with the copper surface, while still benefitting from copper's excellent thermal conductivity. I don't think that flaking is a problem, at least with anything reasonably quality. The copper things I have seen on MD seem to be robust. Mauviel, for example.
