Old-world masters hand hammer the copper to reveal character as the copper turntable adapts to your home environment. Add a touch of elegance to your dining room and ensure everyone can join-in. Acidic substances, such as tomato sauce or lemon juice, left on the metal for a prolonged period of time the finish may react with the metal. Over a few days the living metal will “heal” or re-patina. Copper’s beauty lies in its constant metamorphosis which guarantees no two pieces are alike.
