Abstract:
Anodized aluminum cookware having an exposed copper base or ring is formed by anodizing the completed vessel using a protective cap to cover most of the copper. The portion of copper that is exposed to the anodizing bath only tarnishes slightly and is preferably polished off after a protective lacquer is applied, creating a clean even margin with the anodized aluminum portion of the vessel.
