By the way, when we say tinned, it is with pure tin or an alloy or a generic term like chromium or nickel which are not always so with chromium or nickel but which resemble it ...
Is there a ban on these tinned products.
Tin, it is everywhere in the welds of our pipes ...
Normally tinned is for something covered with tin. Those of ordinary skill in the art will usually use the term appropriate to the coating applied. It's more complicated when there are several layers of different deposits stacked on top of each other .

Because it diffuses heat perfectly, the red copper, formerly called "bronze of Cyprus", remains unmatched
for large kitchen. A diaper food tin, applied hot and dried after use, will remain indefinitely. This tinning whitens the copper but, above all, protects from its acid taste. Tinned copper is maintained in the same way as silver metal.
In any case the lobbies are capable of dressing harmful or even toxic products with the "Food" label .....

Its value lies in the fact that it does not oxidize easily and that it does not form, on contact with food, toxic compounds unlike other metals such as copper or lead.
It reminds me of an anecdote lived with my dentist. Thirty years ago. I learn that amalgams to plug cavities are made, among other things, with mercury. I take offense and ask him for explanations, why a product recognized as toxic will land in our fillings in the mouth in addition !?
He replied (implying that I am a little idiot who understood nothing) that it is a very good product that poses no problems. I resume this conversation some 5 years ago with this same dentist who tells me that these mercury fillings are responsible for many chronic diseases and even heart problems and that it was necessary to remove them from very many patients .... who healed very quickly afterwards.
Moral of this story, a toxic product whatever its "food" form has no place in the food circuit!
