Nonstick and ceramic, and what the coating actually is

There are two coatings, and they are not alike

PTFE — polytetrafluoroethylene, the material sold under the Teflon brand and many others — is a fluoropolymer. It is genuinely the best release surface anyone has made, it is authorized for food contact under 21 CFR 177.1550, and the FDA states that "studies show negligible amounts of PFAS in this coating can migrate to food." It is also a PFAS, which is why it appears in headlines about a chemical class that mostly concerns drinking water and paper packaging.

Ceramic is not ceramic in the pottery sense. GreenPan publishes that its Thermolon coating is "crafted from sand-derived raw materials, Silicon Dioxide (SiO2), and turned into a sprayable solution." It is a sol-gel silica coating sprayed and cured onto metal. It releases well when new, contains no PFAS, and degrades faster than PTFE.

What the PFAS story actually says

The EPA describes PFAS as "widely used, long lasting chemicals, components of which break down very slowly over time", and notes there are thousands of them. That is a real and serious environmental issue. It is also a category that spans everything from firefighting foam to the film on a frying pan, and the risks are not the same across it.

Here is the distinction most cookware marketing blurs. In January 2025 the FDA announced that 35 food contact notifications for PFAS grease-proofers on paper and paperboard packaging were "no longer effective based on the abandonment of these uses". That action was about paper packaging — takeout containers, wrappers — where the FDA said there was "potential for PFAS to migrate to food at levels that may result in a potential safety concern." It was not about cookware coatings, which remain authorized.

You will see that regulatory action cited on ceramic cookware listings as if it were about pans. It was not. That does not make PTFE the right choice for you — it makes the argument for ceramic weaker than the marketing implies, and the honest reasons to choose ceramic are different ones.

The number nobody publishes

Search every nonstick maker's site for how long the coating lasts. You will not find it. GreenPan publishes what Thermolon is made from, what it does not contain, and that it withstands 850F. It does not publish a lifespan, and neither does any PTFE maker.

That absence is not an oversight. A coating's life depends on heat, utensils, dishwasher use and luck, and no manufacturer wants a number on the record that a customer can hold them to. The practical consequence: treat every coated pan as a consumable with a life measured in a small number of years, and buy accordingly. Buying an expensive coated set is buying a wear item at a keepsake price.

That is also why the recommendation on this site is consistent: one coated pan, bought cheaply and replaced without regret, alongside a clad stainless or cast iron pan that lasts. See the best ceramic cookware and the best nonstick pans.

How to make a coating last as long as it can

• Never preheat empty. An empty coated pan on high heat is the fastest way to damage any coating, PTFE or ceramic.
• Medium heat, always. These pans are for eggs and fish, not searing. Sear in something else.
• Hand wash. Dishwasher detergent is aggressive and shortens coating life even where the pan is rated dishwasher safe.
• No stacking without protection. Pan-on-pan abrasion in a cupboard does real damage.
• Replace it when it stops releasing. A worn coated pan is a bad pan, not a cheaper one.
• One household is an exception to all of this. If birds live with you, the material stops being a preference — see cookware when you have pet birds, the only page on this site that gives a categorical answer about PTFE.
