Does Mauviel lacquer their copper cookware
I scored a beautiful copper jam pan (Mauviel - 16 qt) on ebay recently. The seller said it had never been cooked in. It has some black streaks on it that I've been working on with Barkeeper's Friend. My question: does Mauviel lacquer their copper cookware? I do know how to remove it, just wasn't sure if they practiced this or not. Thanks to all!
