Created by the Ruffoni family-owned atelier in the city of Omegna Italy, located in the Italian Alps region. The Ruffoni family has made hand hammered professional copper cook ware for decades and have combined their passion for craftsmanship and technology into the creation of hand-worked copper cookware. The result is a professional cookware item that is a unique and splendid creation worthy for any kitchen and a proud place at your table. Ruffoni hand-hammered copper is set apart from other less prestigious copper items as a professional artisanal product that is hand-made and not mass-produced. 100-Percent copper with interiors lined with durable nonreactive tin. Over time copper develops a rich patina that does not affect the performance of the item. Ideal for gas and electric cooktops. Use of wood or plastic utensils will help to avoid scratching the lining. Protect the lining by not heating an empty pot above 450-Degree Fahrenheit. Ideal for gas and electric cooktops.
