Ceramic coating, sometimes referred to as Thermolon, Ceramica, etc., is a relatively "weak" non-stick coating being used in place of PTFE. This is because it does not produce any off-gases. It's made out of silicone oxide (SiO) during a process known as "Sol-Gel". Silicon is, as mentioned above, listed as a safe product. Most ceramic coated pans require only a single coat on top of a substrate, which is what makes them a weaker non-stick surface. They are more likely to wear and have a much shorter non-stick lifespan than PTFE. What is important to note, however, is that many companies do not list what the substrate underneath is. It may be the actual metal of the pan, or it may be something else to help with its non-stick properties that could be potentially hazardous. As listed on the Thermolon FAQ sheet, the interior Thermolon coating involves a "degrease substrate" and a sand blast substrate. What that degrease substrate is, I'm not sure.

While many parronts have been successful in using their ceramic pans, it's important to remember that overheating anything may or may not produce dangerous off-gasses, as we are currently unaware of what the substrate underneath the ceramic coating is. Please remember to use ceramic pans only on low-medium heats. If you notice that the ceramic coating is chipping, be sure to immediately replace it. And as always, ensure that your ceramic pan is both PTFE AND PFOA free. Some pans are listed as PTFE free but not PFOA, or vice-versa.

EDIT: The "degreaser" is probably just a solvent used to clean the pan before coating it with ceramic, and would evaporate in the subsequent firing, so I don't worry about that. My problem with those pans is the poor quality and short life. Cast iron, stainless steel, and porcelain coated cast iron are the best. [I](Thank you Kentuckienne!).
Adding this to this thread because, 'I know what I am doing'! And I am sure there are many of us, like me, that are lax in this area!
I am at a loss on what direction to go! Was out last night looking for a replacement cook pan, big ol glass lid type. Looking at high end ceramic, I read the label... "As with all cookware, have your bird away from the kitchen in a well ventilated area."!! And a 450f deg limit!
Yes, it was 'everything' free!
My daughter lives here and if it isn't nonstick, she is lost! If it is nonstick, it is destroyed in less than a year!
For years, I have been using the stoneware type cookware, knowing the risks,but being very cautious. Well, I am the cook! Last week, at the wife's house, multitasking, I forgot the pan on the stove! Fortunately, it had butter in it! All good, very burned butter, little smoke! Her Bongo was 20 feet away!
The death from this stuff is very ugly! Other than prayers, little can be done!

As should be, I am spooked!
I have a really nice quality stainless set that no one will use!
