What is nonstick ceramic cookware, and how does it differ from traditional nonstick cookware?
Nonstick ceramic cookware is a type of cookware that features a ceramic-based nonstick coating, rather than the traditional PTFE (polytetrafluoroethylene) or PFOA (perfluorooctanoic acid) coatings found in most nonstick pans. This ceramic coating is typically made from a combination of silicon dioxide (silica) and other minerals, which are baked onto the metal surface of the pan at high temperatures. This process creates a durable, scratch-resistant coating that is also non-toxic and free from harsh chemicals.
The main difference between nonstick ceramic cookware and traditional nonstick cookware is the type of nonstick coating used. Traditional nonstick cookware often contains PTFE or PFOA, which have been linked to health concerns and environmental issues.
