Range Kleen Moneta Azul Gres Non-Stick 10" Fry Pan with Lid is crafted from a proprietary coating process that creates a shiny, non-porous surface unprecedented among ceramic coatings, even under intense and stressful use. When the logo appears on the thermo-chronic flame guard near the handle, it indicates that the desired cooking temperature is reached and heat can be lowered as the aluminum body will maintain temperature. Once the heat is off, the logo will in time disappear, indicating the pan is safe to be touched.
