When you have the Tefal Intens Ceram frying pan set, you can enjoy cooking every day. The frying surface of the pans in the set is 20 times harder* than a regular non-stick PTFE coating. It is so tough that you can confidently use metal utensils. Thanks to the non-stick ceramic Inoceram coating, cooking is easier, and you never have to worry about food sticking. The coating also makes the pans easy to clean. Just add a little detergent and wash with a dish brush and warm water. Rinse afterwards. We recommend hand washing the pans. *The hardness of the surface is measured by an external laboratory using a nano-indentation test, comparing it to a regular non-stick PTFE coating. Thermo-Signal™ and Thermo-Fusion™ The Intens Ceram series frying pans feature an intelligent Thermo-Signal™ heat indicator that turns completely red when the temperature is right for cooking. The pans also have Tefal's efficient Thermo-Fusion™ induction base, ensuring quick heating and even heat distribution throughout the pan's base. This results in perfect cooking surface, texture, and flavor of the food. Inoceram Glide, non-stick ceramic coating 20 times harder frying surface
