NonStick cookwares have a coating of either Teflon (PTFE) or ceramic.
Food is not going to stick on nonstick cookware.
Nonstick cookwares are very easy to clean.
It is safe to cook on nonstick cookware at medium temperature.
But if the temperature is raised above 500°F (260°C), toxic substances can mix with food.
This can make you really sick.
To cook healthy, consider buying ceramic coated cookwares. They are PFOA, PFAS, and PTFE free.
