Polytetraflouroethelene (PTFE), a long-chain molecule, is a popular non-stick coating used in cookware. Invented by Dr. Roy J. Plunkett of Dupont in 1930, PTFE is one of the miracle materials of microwaves. Many people have reported instances of the coating inside their microwaves flaking off or showing signs of wear and tear. However, it is generally safe to use Teflon in the microwave, as it is not typically present in ovens due to its rapid degradation at regular cooking temperatures.
Teflon is used in electrical appliances, with the electrical industry accounting for at least 50 of Teflon production worldwide. Experiments on Teflon have shown its high resistance to heat, water, and radiation. While microwave radiation is not risky, there are health concerns about heating up plastic. The latest research suggests that microwave ovens and Teflon coated pans are not dangerous, as they would degrade rapidly at regular cooking temperatures.
PTFE is used in almost all coax cables and soft substrates, and the non-stick CleanRelease interior coating is made from a material like Teflon or ceramic. Although not cheap, PTFE has a dielectric loss rating of.0002 @ 3GHZ, will not absorb moisture, and has little or no insulation. Printed circuit boards used at microwave frequencies often use PTFE as insulation, which is vital for safety. Arcing is the term used for describing sparks in the microwave oven, which can be caused by metal or foil touching the interior side or back of the oven.

To determine if pans are oven safe, consider that they were fabricated at high temperatures and be careful with extraneous …
What material should you never put in your microwave?
Metals like stainless steel and aluminum should not be used in a microwave due to their potential to reflect microwaves, increasing heat and potentially causing a fire. If storing leftovers in metal containers, remove the food and place it in a microwave-safe container. Aluminum foil can be microwaved, but its surface must remain flat to prevent “arcing” and potential damage. Wrinkles or crumpled foil can cause electric sparks to shoot across the foil’s surface, potentially damaging the microwave or causing a fire. Food wrapped in aluminum foil may not cook or reheat properly in the microwave due to the foil reflecting radio waves.
Measurement of microwave-safe containers is generally based on the back or bottom of the item, but there may be exceptions. If unsure, check the back or bottom for a microwave-safe label or symbol, or determine the item’s composition to determine its safe use. If unsure, leave the container out, as this ensures the microwave will stay in top shape for years to come.
What paint is used inside a microwave oven?
The item in question is a Rust-Oleum AE0090001E8 400ml appliance enamel white.
Is a microwave safe?
Microwaves are non-ionizing radiation, meaning they do not pose the same risks as x-rays or other ionizing radiation. However, they can heat body tissues like food, potentially causing skin burns or cataracts. Manufacturers must certify their microwave oven products to meet strict radiation safety standards set by the FDA. Microwave energy will not leak from a microwave in good condition, but damaged ones may present a risk. Contact the manufacturer for assistance if the door hinges, latches, or seals are damaged or the door does not open or close properly.
Microwaves are a form of electromagnetic radiation, consisting of waves of electrical and magnetic energy moving through space. The human eye can only detect a small portion of this spectrum, while radios and X-ray machines use different portions.
Is there Teflon in microwave popcorn?
The bag lining contains chemicals like perfluorooctanoic acid (PFOA), which is used in making stain-resistant materials like Teflon and pizza boxes. PFOA has been linked to liver, testicular, and pancreatic cancer in animals and may also cause infertility in women. A study at the University of California, Los Angeles found that these chemicals may prevent childhood vaccinations from working properly.
Children with higher concentrations of these chemicals in their blood have lower protection against certain childhood diseases. The chemicals enter the bloodstream through microwaving and accumulate in the body for years, according to Olga Naidenko, a senior scientist for the Environmental Working Group.
Why do chefs not use Teflon?
Non-stick cookware is fragile and requires constant maintenance to prevent damage. It’s not dishwasher-friendly and requires gentle hand-washing to prevent tearing of the Teflon coating. Professionals dislike non-stick frying pan sets due to their non-oven-friendly nature and inability to use metal utensils. The Indus Valley offers stainless steel pans as an alternative, which can handle rough cooking and cleaning with minimal maintenance due to their sturdy nature.
Is Teflon safe in the microwave?
Teflon™ nonstick coatings are safe for use in a microwave oven, although the suitability of metal-based cookware for this purpose has not been established. It is advisable to consult the manufacturer’s guidelines for instructions on the correct use of the product. Teflon™ coatings can be stored in a refrigerator and are capable of withstanding high temperatures.
What are microwave interiors made of?
Microwave cavities are made of metal, with interiors either stainless steel or painted steel with a special coating. Convection models are made of stainless steel for easier cleaning. The walls are not painted like typical microwaves, as they can heat up over 400 degrees Fahrenheit in convection cooking mode. The mesh screen in the window is also metal to prevent microwaves from passing through glass or plastic doors.
All microwave cavities are “tuned” to specific sizes and configurations, and adding metal utensils can disturb the planned pattern of microwaves and cause arcing from the metal object to the nearest grounded object.
Is it safe to use a microwave with the paint peeling inside?
If the interior coating or paint is flaking or peeling inside the oven cavity, discontinue use and replace it. The microwave is not repairable and meets government requirements for food-contact surfaces. No lead or toxic materials are added to the cavity coating material. Inadvertent ingestion of small amounts of peeling coating does not pose a health risk. There is no approved repair method for chips, burns, or scratches to the interior coating.
What is the metal thing inside a microwave?
Microwave ovens use metal to reflect microwaves, focusing them on the food to be cooked. Food molecules absorb microwaves, generating heat that cooks the food. Metals like forks, knives, and spoons are great conductors of electricity, but when they hit metal objects, they can cause problems. If there isn’t enough material to absorb the reflected microwaves, arcing can occur between the metal object and another part of the microwave oven, causing a miniature bolt of lightning that can damage the oven by starting a fire, burning a hole in the wall, destroying the magnetron, or damaging sensitive electrical components.
What is the best material for inside a microwave?
The lining of microwaves may be constructed from a variety of materials, including stainless steel, which is resistant to corrosion and staining. Alternatively, painted steel and paint may be used, with the latter offering a range of coating options, such as anti-fingerprint treatments, which enhance safety and functionality.
What is the film on the inside of a microwave?
A transparent plastic sheet is affixed to the microwave door to prevent interference with the metal screen. In the event of removal or damage to the microwave, it is imperative that the device is not utilized and that the appropriate servicing personnel are contacted. In some instances, a white plastic strip or tape may be observed on the door of the microwave, situated where the window meets the frame. In the event that repairs are required, an appointment should be scheduled with GE Appliances Factory Service.
📹 The Truth About Non-Stick Pans: Ceramic vs. Teflon

I noticed you like to cook eggs in teflon with butter, and cook eggs in ceramic dry. Just because ads claim you don’t need butter (or any oil) doesn’t mean you should cook dry. I’ve got a 5 year old ceramic pan that I use multiple times a week. I never cook foods dry, and it is still my favorite pan. I’ve also got teflon pots that are only 2 years old that have scratches and are starting to flake.
Regardless of PTFE pans being considered safe by the entities you mentioned, I realized a group of 5 EU countries submitted a request to EU, the “PFAS restriction proposal”. This is very general, for the environment and health, however, when we look deeper into how PTFE pans are made, they are made with PFAS, and when misused, can generate PFAS. So, I believe that so far, the information about PTFE pans and its connection to PFAS is very scarce and minimal to be able to consider (at least for myself) nonstick pans made of teflon safe. I am actually wanting to get a new pan set, coming from broken teflon pans and stumbled upon a lot of pan-content. Then I realized this request is just new but might be the begining of a new ban to nonstick teflon? Anyway, now I am doubting among ceramic vs stainless steel, I am just an average everydaycook, but there are way too many options out there.
I have a couple of ceramic pans. My oldest one has lost some of its slipperiness but I have found that if I put some lemon juice in it and let it sit overnight and give it a good cleaning the next day it is still very serviceable. I have one that I reserve only for eggs on Sunday and I keep it covered when not in use so it’s not banging around with my other pans. I’ve had it over a year and it’s still like new.
Hold on. Ceramic cookware is silicon dioxide, a form of glass. What you know as window pane glass is mostly that but with additives that make it flow better and reduce its melting point, but unfortunately also make it the tiniest little bit water soluble – sometimes the amount isn’t right and it make glass actually water soluble outright, but in the usual amount it is water resistant but already somewhat hydrophillic. If you avoid these additives, you get a water repellent surface. Where does silicone oil (siloxane) come into play at all? You sure you’re not confusing things?
You argue that oneTeflon pans are more environmentally friendly than two ceramic ones, however, you skip over the fact that PFOAs barely biodegrade… at all, and are expected to remain on Earth for literally thousands of years. That’s a huge problem considering these substances have only been around for about half a century and yet every single human and animal has it circulating in their blood.
My reason for liking ceramic pans better than Teflon is they’re clearly tougher not for environmental reasons. Any Teflon pans I ever used degraded no matter how much I babied them, I’ve got 3 yo GreenPans that I use non-stick spray or butter on, limit the heat to medium, only use wood or silicone utensils – they’re holding up fine so far. For higher heat I used stainless or carbon steel. Maybe newer Teflon is better but no interest.
What has not been mentioned is etching of the ceramic surface. Acidic material are fine but those with alkali can be detrimental long term to glass/ceramic cookware. Any foods with alkali, sodium hydroxide, and such are be long term problems with silicon dioxide cookware. These can be anything from ramen noodles to chocolates to even some olives. Heat and high pH foods will take their toll on ceramic cookware and make them have very fine pits which will cause food sticking. .
As a cook with a Ph.D. in Ceramics, I can’t find any fault in your findings regarding the longevity of Teflon vs. ceramic coated pans. But I’m going to quibble over your definition of what is and is not a ceramic. Materials are generally classified by what type of bonding holds the material together. The atoms in metals are metallically bonded and the atoms/ions in ceramic materials are held together by covalent or ionic bonds. Silica, silicon dioxide, SiO2 is a ceramic. It is a “mineral’ if you dig it up and clean it and/or crush it. It is a ‘ceramic’ if you synthesize it. If it has an amorphous, non-crystalline microstructure you can call it glass. It would be more accurate to call it a “silica” or “sol-gel silica” coating, but it comes down to marketing. I would be interested if you could post the source of that says that silicone is released by the coating. I have never heard that before. If true, that’s a dumb way to make a non-stick pan, in my opinion.
This is a Paid Ad for Teflon Manufacturers, not an honest review. The chemicals in PTFEs and PFOAs and used in manufacturing the same are still an environmental danger. Also, it’s not hard to heat a pan to 500 degrees and release the toxic fumes. That said, the environmental danger is greater than the personal danger. “Teflon” is the least durable cooking surface known to man. I don’t us a lot of “ceramic” cookware, but it most certainly far outlasts Teflon. I have multiple ceramic coated pieces that are far older than any Teflon pan has survived for me. I mostly use cast iron cookware, much of which is over 100 years old, much of my stainless steel cookware is decades old, my carbon steel pan will last for decades.
What you actually said was Teflon bought out the market and paid to get into the FDA club to minimize competition. You also contradict yourself by stating ceramic breaks down much more quickly in extreme temps and doesn’t last long, suggesting Teflon is superior in longevity and then follow all of that up with tips to prolong your Teflon pans 😑 I own one of the shittiest cheapest ceramic pans from target and use it mostly for cooking eggs because my well maintained commercial grade Teflon skillets stick. Unless you have heavy amounts of oil in Teflon, everything sticks my guy… Now don’t get me wrong, My argument is not about whether or not ceramic is safer or healthier, but I think it’s really stupid to suggest Teflon is the “everything” pan. Obviously cast iron is the king of pans, but Teflon belongs sauteing, searing and braising and that’s that. You can cook protein on ceramic, wipe it out, adjust the pan temp and minimally grease the pan to cook eggs and you won’t get any sticking.
No matter how well they advertise it and what they say, non stick ceramic is absolute crap that ruined all my food after the first use (not sure what sort of synthetic coating they used which I guess came off and stuck to all the food I cooked) On the other hand Teflon is really good but I won’t use it ever again after I learnt about its health effects. So I made a decision to stick (no pun intended) to occasional cast iron BBQ, or no frying at all.
Man, this sucks. I own Teflon cookware that needs replacing because of scratches. I just bought a set of ceramic cookware that was on sale, but I’ve never had any. Now I’m thinking about returning it for another set of Teflon, since it lasts longer. I do love Teflon, & the only negative is the scratches being toxic.
Ceramic as enamel wher as widly used back in the days and there are still items as buckets and cups from the 50`s in use as good as new and there are also new cups that are quite expensive cause of the process, we got some of those and they are exellent. Are affordable pans treated the same? No sheap pans are coated with “enamel paint” and then heat treated with an much lower temperature, “car painting” A way softer surface and as with an car I do not work it with harsh materials.
Ceramic pans are actually made from ceramic coated metal. The sol-gel you mentioned is a process through which this layer on the metal pan is created, the coating is not made of a gel. Im also not sure where you are getting the silicone oil bit from, silicon and silicone are different things despite the similar name. Im probably gonna stick with carbon steel etc though, but certainly not PFAS
Thank you once again. I’m so glad I discovered your website. I really love to cook & I like to use good things while doing so. A couple of years ago I threw away all my nylon utensils & bought silicone (I kept my stainless). Thought I may have to do the same with my teflon cookware, but it appears that wont be necessary for newer teflon products.
So I’ve been seeing Zwilling 3 Ply Stainless Steel ceramic coating cookware pieces at my local Ross stores here in LA selling for roughly 50% off of retail prices….They’re very heavy duty in build quality like Cuisinart, Viking and All Clad Stainless tri-ply cookware. I can’t find any reviews of Stainless steel cookware with Ceramic Coating anywhere on YouTube…..This needs to be covered by your website or one of your friends who do cookware reviews please
Those “non-stick” coatings are just high temperature plastic. I suspect the “ceramic” coatings are just silicone dioxide or titanium oxide annealed with another strain of high-temperature plastic. A frying pan with plastic coating? I think now that we are in the information era, and people can look up on the internet different opinions on how to season their frying pans with crisco or coconut oil and peanut oil. Heck we have non-stick spray! Why should we have plastic coated pans that are toxic plastic that wear out quickly when we have the options of endless renewal with cooking oils soaked and seasoned on cast iron, high carbon steel, and even stainless steel? Even without PFAS, plastic coatings are bad. It’s madness. Plus calling them “ceramic” coatings is a joke. The definition of “ceramic” is kiln baked clay. The glaze on ceramics is called glaze or glass enamel. They should just make all that plastic coating on cookware illegal. Electric waffle irons are the worst. I can’t wait until they figure it out and you can buy plastic free waffle irons. You can get cast iron or a mixture of cast iron and aluminum stove top waffle irons with no plastic coatings, but not electric except in some high end commercial models.
However, ANY applied “non-stick” coating is going to ware off, eventually……it could be anywhere from a few weeks to a few years, depending on how they are used……but it will begin to release! And now, because of the internet, we know how to make SS, cast iron and carbon steel virtually non-stick, through the proper use and application of heat, seasoning, oil and fat.
I thought the base also determines how safe a pan is. I heard about bad things about aluminum, for instance. I have purchased a couple of ceramic stainless steel pans for that reason, and I don’t think stainless steel is very common among Teflon pans. I could be wrong. Can you do an episode on aluminum pans? That will be very helpful.
I think it’s slightly misleading to state that you can gain a percentage of purchaser complaints from the manufacturer’s reviews on their own website. I believe your math, but it’s the percent of “reviewers” on the site where the reviews were not removed or taken down. Amazon reviews might’ve been a better choice to use.
New technics for Teflon manufacturing are safer and then your part it is very important, do not overheat Teflon cookware, do not scratch with wrong utensils, use always silicone made utensils and washed by hand with a microfiber scrubber and always do the light test, means with a led flashlight look for small scratches every 3 months, this is what I keep my cookware safe.
Wait a moment. You said ceramic cookware releases silicone oil, which is why it loses its non-stick surface over time. So, for the obvious question, is silicone oil safe to eat when it is released from the pan into your food. I find no information about this through a google search. Silicone oil is sold as a lubricate such as in the product called “3-IN-ONE”. If you look at its package warning label it says, “Do Not Swallow”. So how again is ceramic coated cookware safe when it releases silicone oil into your food?
You sound very confident that this “stewardship” program makes any concerns about PFOAs irrelevant. The EPA has very limited ability to police these manufacturers. While cooking with Teflon pans won’t necessarily cause ingestion of PFOAs you have no guarantee that the factory in china that made it didn’t dump C8 or other chemicals into the rivers and waterways. Teflon pans are for lazy people that don’t know how to cook.
I still use the old fashioned seasoned cast iron pans. Its like everything else, if you know what you’re doing, you won’t have problems. I dont use teflon or cermaic coatings because its too easy to char what you’re cooking, and thats due to how thin they are. You have to dial in your heat very carefully and watch it like a hawk. With thicker cast iron that doesnt conduct heat as well, its very forgiving.
“Great review on these non-stick pans! It’s important for viewers to be aware of the types of non-stick coatings used in these products, especially concerning PFAS. Products like the Made In and All-Clad pans use Teflon (PTFE), which is typically free from PFOA now due to health concerns but still warrants cautious use and understanding about high-temperature safety. On the other hand, the Caraway and GreenPan lines feature ceramic coatings, which are marketed as PFAS-free alternatives, offering a different set of benefits and considerations regarding durability and heat distribution. For anyone looking to minimize their exposure to PFAS, opting for ceramic-coated pans like those from Caraway and GreenPan can be a safer choice, especially as they avoid the potential risks associated with traditional non-stick coatings like Teflon. Always ensure to follow manufacturer guidelines to maximize the lifespan and safety of whichever cookware you choose!”
Sorry still dont trust either product or the data these big conglomerate put out! Stick with good quality stainless stell that it nothing else why risk your life and your family, all you need to do is heat the pan up long enough so water beads, place in butter, let better warm to temp of pan and egg will never stick, done!
Get away from the products Ceramic (not really ceramic) & Teflon and any other non stick product. Stop shooting for non stick. Just stop. Stainless Steel. Carbon Steel. Cast Iron. Glass (Pyrex strength). White Porcelain bakeware. No other product is needed. Real products have weight and require care. Some require replacement after many – many years. Learn em > use em > love em.
I absolutely agree with your article. I have had 3 ceramic coated skillet pans and in my experience, I would only get around 10 to 20 uses before the sticking problem became so bad that the pans were useless thereafter. PTFE and similar chemistry has been around a long time and has always been a good non-stick coating. There is always a study coming out demonizing whatever is commonly used in order to make market room for something new. I’m very skeptical about the “studies” that show PTFE being any more harmful than using most everything else today such as detergents, cosmetics, pharmaceuticals, … you name it! Remember the “Better living thru chemistry” philosophy of a few decades back? Well were in it, like it or not.
