Calphalon
Calphalon was founded in Ohio in 1963, originally operating under the name Commercial Aluminum Cookware and manufacturing products exclusively for professional chefs. The company’s founder, Ronald M. Kasperzak, is credited with having invented hard anodized aluminum cookware several years later, in 1968, using a process adopted by the aerospace industry. Soon, Calphalon cookware was so in demand that it expanded to be available to home cooks. Today, Calphalon pans and pots, as well as the company’s wide selection of bakeware and cutlery, are used in homes and professional kitchens around the world.
Are Calphalon Nonstick Products Right for Your Kitchen?
First, let’s answer the question, what is hard anodized aluminum? It is aluminum that has undergone a special kind of anodization process that involves exposing it to a high-voltage electrical current, as well as a chemical bath at very cold temperatures. This results in the metal developing a hardened oxide layer that makes it especially durable and prevents it from being affected by the acids in food. Best of all, almost all hard anodized aluminum cookware is nonstick.
