发明名称 Cookware with Tarnish Protected Exterior
摘要 An article of cookware in the form of a cooking vessel exposes only a portion of a copper inner layer on the upper portion of the exterior sidewall. The layer does not change color or tarnish as it sufficiently distal from the bottom of the cooking vessel that it is not subject to direct heat and oxidation during normal use. The unique bright color of the native copper is further protected from tarnish caused by fingerprint by a protective coating that can withstand moderate heating.
