The JML copper stone pan set gives you the strength of stone with the beauty of copper. The pans provide unparalleled heat distribution and class-leading levels of scratch-resistant durability. With deep sides and ultra-non-stick lining, this copper stone pan set is perfect for every kind of hob and every kind of food. From slow, simmering sauces to ultra-hot sticky caramels and jams, these pans will take whatever you throw at them and always come up looking good as new. The secure-fitting glass lids have a ventilation hole to prevent over-boiling when cooking with extra-hot liquids like jams and caramelised sugars that can be dangerous. The vent allows excess steam to escape while still holding in enough heat to allow you to simmer, boil and slow-cook whatever you want. The unique copper stone, non-stick surface is supported by a forged aluminium core and a stainless-steel base that makes the ultimate, durable pan for perfect heat distribution and even results with no hot spots. These incredible saucepans come in 16cm, 18cm and 20cm sizes.
