Did some research this is what I found. I don't have them so I'm not sure exactly.
This is from their website.
"Every piece has the same natural ceramic cooking surface so it's SUPER easy to clean. But, perhaps best of all, they will never flake or release toxic gases."
And this from another site where someone asked about them as well.
"OrGreenic cookware has a ceramic surface over an aluminum body. This means that it presumably won’t flake, scratch or wear-off into your food.
A scientist friend of mine says the aluminum molecules are small enough to seep through anything when heated.
If I were going to use something besides my cast iron pans, I would use the PerfectGreen pans.
The PerfectGreen™ Fry Pan features a Duralon coating that is 100% free of PTFE, PFOA, Cadmium and BPA. The Nuwave Perfect Green pan is made out of a high quality 18/10 stainless steel all natural coating and double layer of diamond infused nano-ceramic duralon coating."
Hope this helps!
