Circulon Classic’s hard-anodized aluminum construction means great heat conduction, and the glass lids allow food to be monitored while it cooks without releasing nutrients or moisture. Classic features the TOTAL® Food Release System of circles to reduce surface abrasion, and is coupled with DuPont Autograph® advanced 3-layer nonstick to deliver extraordinary food release and easy cleanup – and it’s metal utensil safe. The phenolic handles are comfortable to the touch and oven safe to 350°F.
