Bottom separates for easy release and even heat distribution. Durable nonstick Quantum II coating on interior and Xylan coating on exterior keeps food from sticking. This new range of baking tins is a home baker's dream. Each piece has been smartly designed to help turn out showstopper cakes and melt-in-mouth dishes time after time.
