You might be wondering about that ceramic coating (vs Teflon) when it comes to buying non stick pans. If you’re not sure of the important differences between pans with PTFE and non stick pans without Teflon (ceramic) read on. Here’s what I’ve discovered since looking at the ins and outs of Teflon vs ceramix nonstick cookware.
Nonstick ceramic cookware vs. Teflon
Which is better, ceramic or Teflon?
People will ask, “Is ceramic better than Teflon” for nonstick cookware? In certain ways, yes. I cover these in my ceramic cookware guide.
But, it is better to know the characteristics of each and how best to care for and use them, and then decide.
Let’s start with Teflon.
What is Teflon made of?
The manufacturers, Chemours (a spin-off of DuPont) describe Teflon as a synthetic resin of polymerized tetrafluoroethylene (PTFE). So, the main constituent in Teflon is this polymer, PTFE.
How do they make Teflon pans
This PFTE formula is sprayed over a metal base to provide nonstick coated cookware.
Discovery Channel shows the making of PTFE pans in this short video…
A note about PTFE vs Teflon
Teflon is a trademark. You’ll see it written with a capital letter and sometimes with the trademark symbol. Cookware carrying this trademark will have a coating of PTFE.
So, in terms of PTFE vs Teflon…
Teflon is a brand of coating that contains the compound, PTFE. Whereas, PTFE itself is a chemical compound that has a number of applications.
Now, let’s look at ceramic.
How do they make ceramic nonstick pans?
Ceramic nonstick cookware is made in a similar fashion to that shown for Teflon. The main difference is the ceramic coating vs Teflon.
Does ceramic non stick have Teflon in the mix? No. The typical ceramic nonstick coating does not contain Teflon. It is made from natural sand applied using sol-gel technology. I wrote about the coating process in ‘how they make ceramic cookware‘.
But, just to cover it here…
Why are ceramic pans non stick? Instead of using the polymer, PFTE, to prevent food from sticking, a coating of the sol-gel sand formula gives the pans a glass-like finish.
Yes, but why is ceramic
Now let’s look at how these two nonstick types are similar.
Similarities: nonstick ceramic vs Teflon cookware
- Both are marketed at similar prices
- Both products are non-reactive
- Both need care to not scratch the cooking surface
- Both best to avoid cooking with high temperatures
- Both claim to be free of PFOA (Teflon since 2012), which I cover below.
Teflon vs. ceramic cookware care instructions
Both Teflon and ceramic non stick pans need certain care to extend the life of their nonstick surface. Deteriorating surfaces happen with ceramic coated pans just as easily as they do with Teflon pans with use over time.

Bare aluminum cookware is not what you want for cooking, as my article on choosing the healthiest cookware explains, whether it is a ceramic
Use Non Metal Utensils
To avoid scratching Teflon or ceramic coated pans, use only bamboo or wooden spoons, nylon spatulas, or other utensils suited to non stick cookware.
This means stay away from metal tongs and egg-flippers with both Teflon cookware and pans with ceramic coating.
Hand Cleaning Is Recommended
With the nonstick surface intact, cleaning is simple. A light handwash without abrasive scourers or a wipe with a paper towel is all that is needed for cleaning both Teflon and ceramic nonstick cookware.
It’s always best to follow the instructions for individual cookware.
Stick To Safe Heating Temperatures
There are health concerns about PTFE (see below) when heated at high temperatures. Whereas, cookware with a ceramic coating can be heated without health concerns.
In either case, very high-temperature use is unwise for both as this can quicken the deterioration of the nonstick surface and thus reduce the life of nonstick cookware.
Manufacturers tend to advise users to cook at low to medium heat for both types of nonstick cookware.
Now let’s cover the safety concerns.
What is safer, ceramic or Teflon
Is teflon safe?
This is probably one of the main questions people ask: Does Teflon cause cancer?
The concern with Teflon and cancer relates to using PFOA (perfluorooctanoic acid), which is a strong acid and considered carcinogenic to animals. 4
DuPont claims that since January 1, 2012, PFOA has not been used in their nonstick coatings for cookware and consumer bakeware.
Another often asked question: Is Teflon toxic? This is what the manufacturers, DuPont, say:
- “The U.S. Food and Drug Administration (FDA) has found that Teflon™ nonstick coatings for cookware are acceptable for conventional kitchen use. The U.S. Consumer Product Safety Commission rejected a petition in 2003 to require a label warning for nonstick coatings. The U. S. Environmental Protection Agency (EPA) does not believe there is any reason for consumers to stop using any consumer or industrial related products.” — www.chemours.com, accessed Sept 2019 2
Is Teflon Bad for You?
It’s best to avoid cooking with Teflon at temperatures above 482 °F (250 °C), as some technical studies ¹ claim this is where the PTFE coating starts to deteriorate and become concerning for health.
DuPont admits that Teflon gas, emitted when the cookware is overheated, is toxic. This is thought to cause ‘Teflon flu’ in humans.2, 3 The toxic fumes are said to irritate eyes, nose, and throat and cause respiratory distress, with symptoms likely to last 24 hr.2
The particles scratched from Teflon pans, however, are not considered harmful.
Does Teflon Coating Cause Harm to Birds?
Environmental harm is one of the concerns associated with Teflon.
As noted above, the coating deteriorates at temperatures on high heat settings. The breakdown products emitted with overheating can be lethal for birds. ²
DuPont warns: “birds have extremely sensitive respiratory systems, bird owners must take precautions to protect them” (www.chemours.com, accessed Sept 2019). 2
If you have birds, you may want to steer away from Teflon or at least make sure your birds are well away from the kitchen and the exhaust vents. Unless of course, you can ensure you maintain cooking heat at low to medium.
Is ceramic safe?
The ceramic technology that offers a pan without Teflon is said to be healthier because it is PTFE and PFOA free, as well as free from cadmium and lead, and hence considered toxin-free.
You can read more about whether the ceramic coating is safe in my article on the safety of ceramic nonstick cookware.
Does ceramic cookware have teflon?
No ceramic cookware does not typically have Teflon. Solid ceramic cookware is purely ceramic material. Ceramic nonstick cookware has a ceramic coating made from sand (silica) and applied in a polymer to a metal base. I cover this further in ‘how ceramic cookware is made”.
Summing It Up
My thoughts on ceramic coated cookware vs Teflon is that it’s best to throw out that old scratched nonstick pan and check out your options.
Looking for non Teflon pans for reduced-fat cooking as a healthy alternative to normal cooking? Why not consider ceramic non stick cookware. Or for a pan that lasts and lasts, a cast iron skillet, which when seasoned will provide the sought-after nonstick performance.
