We have two types of coating: PTFE and Ceramic.
PTFE: commonly known as Teflon, it is a non-stick coating, very effective and ideal for cooking eggs, fish, vegetables and simmering. The non-stick PTFE begins to deteriorate from 260ºC, so it is not suitable for cooking above this temperature. Since a few years non-stick PTFE are free of the PFOA molecule.
Ceramic: ATTENTION! It's not a non-stick! It has the appearance of being non-stick, for its outermost layer of about ten microns of silicone, but it will disappear after several uses and cleaning cycles.
However, the ceramic coating allows food to be sealed at high temperatures (360ºC) while ensuring easy cleaning. This coating is particularly suitable for aluminum tools, ideal for cooking at high temperatures (grill, grill, wok, pressure cooker ...).
