This covered skillet, measuring 9.5" (24cm), fries three large breasts of chicken, sautes a large cluster of vegetables or with the lid on, braises collard greens or spinach. Beneath the diamond crystals, the pan is constructed of heavy, 100% recycled cast aluminum (a consistent heat conductor) while its extra thick base resists warping for cooking safely on any type of cooktop. The comfortable, ergonomically-designed handle and knob on the lid stay cool during cooking and are oven-safe to 500°F/260°C. The heat-tempered glass lid is clear to prevent overcooking and has reinforced stainless steel rims for added durability and an adjustable steam vent for advanced moisture control. Swiss Diamond's revolutionary diamond-reinforced cookware outperforms cookware with titanium surfaces by 25% and provides a Limited Lifetime Warranty to back up that claim. Made in Switzerland.
