Our high tempeature ceramic non-stick is among the finest non-stick systems in the World, made from purified sand, rock and ceramic. The non-stick surface cleans in seconds and has a heat-tolerance nearly twice that of PTFE non-stick.  No gasses or fumes are ever emitted at ANY cooking-temperature.  The non-stick contains none of the components used for making PTFE non-stick and is safe for unrestricted food-storage, dishwashers and aerosol cooking sprays. Our non-stick surface is essentially a non-porous glass surface that tolerates rapid cooling and heating.  Its fine “food release” properties are the result of the ultra-smooth surface.
