Heavy gauge, highest quality for those who love to cook, to eat, to serve. Our line of Paella Pans work beautifully on the burner, in the oven and on the grill for anything you'd like to prepare. Traditional hot tin lining, the original non-toxic, non-stick lining for cookware for over a thousand years. We prefer to allow the living finish to show the work, age and season of our pans. Polish it if you must or your mother in law is coming over. The shine we've beaten in can always come out again.
