Scanpan spent more than two years researching and developing to create the Stratanium nonstick system from the ground up. Stratanium consists of 5 layers in which hard particles and wave-like layers interlock to reinforce the nonstick layer. This makes Stratanium products have a 50% more durable nonstick than the previous surface. Made In Denmark. Oven and Broiler safe up to 500 degrees.
