Marrying their traditions of quality and stainless steel know-how, Zwilling introduces the stainless steel Spirit cookware collection: a stylish and durable series for serious home cooks. The 3mm-thick cookware is made using fully clad stainless steel with a thick aluminum core for even and responsive cooking. The interior is coated with FDA-approved PTFE- and PFOA-free Thermolon granite ceramic nonstick, so it's safe for you and the environment. The manufacturing process of this eco-friendly coating produces 60% less carbon dioxide than traditional nonstick and does not release toxic fumes. Plus, it allows you to cook with less oil and food easily slides off with no mess. Flared rims allow you to pour liquids without dripping, and the riveted cast handles stay cool even on electric and gas stovetops. Cookware is compatible with gas, electric, halogen and induction cooktops and is safe for the oven and broiler up to 500°F.
