With a Tefal pan with ceramic non-stick coating, you can cook PFAS-free. That's because this coating doesn't have any chemicals in it and is stronger than a standard non-stick coating. This makes the pan last longer. Thanks to the smooth base, you need little oil or butter. The Tefal pans with ceramic non-stick coating have a Thermo-Signal dot in the middle. The dot turns evenly red when the coating is hot enough. That's useful, as you know exactly when to put the ingredients in the pan.
