Something I learned about copper cookware when I was a young bride- Modern stuff comes lacquered and is considered for decorative purposes only. This has to be removed if you want to use it to cook. If you do it wrong, it can come out uneven, chemical burn the piece and discolor it and the remaining lacquer. I ruined at least one pot. I'm wondering if that is what I'm seeing on this pot. I would use copper polish on it and see if it comes clean or if you have discoloration issues. The inside looks like it is "tinned". If so the surface will be kind of powdery and it comes off. I'm not sure of the safety of cooking with tinned cookware, so do a little research before your next pasta dinner!
