The Berndes SignoCast Collection heats quickly and uniformly for even browning on the cooktop. The casting technique allows a design of thick base and thinner side walls for maximum performance and minimum weight. The 3-layer nonstick interior and 2-layer nonstick exterior surfaces protect foods from sticking and burning. They are exceptionally easy to clean and facilitate fat-free cooking. The handles are also specially designed to stay cool on the stovetop for easy transporting and are oven safe to 450F.
