The copper and brass ones I had in my restaurants were all tinned, but
I've seen untinned ones. The poisons are created by cooking acid foods
in the bare brass or copper. Verdigris or "green-gray" in French.

As I understand it, the cooking had to include reasonably strong acids,
cooked for a long time to be serious issue. Both antique and modern
jelly pans are often made of unlined copper or, more rarely, brass.
