~ Factory sealed, brand new 3 qt sauce pan with glass lid from the coveted Signature collection by Calphalon. ~ Signature non-stick cookware differs from other non-stick cookware in that it features a proprietary, textured non-stick surface that mimics the results of stainless steel when it comes to searing and sealing in flavor of meat, seafood, and vegetables. ~ Signature boasts a five-ply construction with a three-layer core of heavy-gauge aluminum fused between two layers of stainless steel for even heat conduction and longer heat retention. ~ Signature non-stick is oven safe at a higher temperature than Contemporary (500 degrees F) and is scratch resistant against metal utensils. ~ The Signature collection is more expensive than other collections due to its unique non-stick surface and 5-ply construction.
