Wellness Mama » Blog » Natural Home » Are Glazed Ceramic Pans Safe?

I’ve been slowly switching my kitchen over to ceramic pans since I had the chance to try ceramic cookware last year. I researched cookware options for months and wanted to find an option that was:

  • Easy to clean
  • Cooked evenly
  • Was non-scratch or non-stick
  • Most importantly: non-toxic

I finally settled on Xtrema ceramic cookware and have been really happy with it.

Since then, I’ve received a few emails asking for more information to support the safety of the glaze used on ceramic cookware.

Is Ceramic Cookware Safe?

I reached out to the company I got my cookware from to find out more information and received this reply:

“Our Xtrema cookware is made of 100% inorganic ceramic minerals and so is our ceramic non-scratch glaze. All ceramic glazes are made of various inorganic minerals and oxides. The oxides give the glaze it’s strength, color and glossiness. Our ceramic cookware and it’s ceramic glaze contain no metals or lead and cadmium. In the USA all ceramic products have to pass California Prop 65 before the product can be sold in the USA. I have attached an article about California Prop 65. Also, we continue to test every shipment that is made to guarantee that our product passes the California Prop 65 standard as well as the USA – FDA standards for lead and cadmium.

We publish our test results on our web site: https://xtrema.com/pages/product-testing We have never found any other cookware company in the world that publishes its tests results for heavy metal leaching as well as their California Prop 65 results for lead and cadmium.”

Why Ceramic?

I personally use ceramic since it cooks evenly and doesn’t leach chemicals. I also have cast iron and stainless steel and use them occasionally, but even “safe” cookware options can be problematic. I avoid traditional non-stick and aluminum pans completely…

From this article:

“Teflon cookware is probably the all-time worst of all cookware. Johns Hopkins Medical Center says the chemical PFOA, used in manufacturing Teflon, is now found in the bloodstreams of nearly everyone in the U.S. Early studies suggest that high PFOA blood levels in humans are linked with cancer, high cholesterol levels, thyroid disease and reduced fertility. Teflon surfaces break down and end up in your food and when heated to high temperatures, emit fumes which cause flu-like symptoms in humans (AKA: polymer fume fever) and can be fatal to birds. Manufacturers have to eliminate PFOA from all cooking products by the year 2015.

Aluminum cookware is one of the most common cookware to use, but can be very toxic as this heavy metal is absorbed into all food cooked in it. The aluminum released into foods during cooking ends up in your body. Excess aluminum has been associated with estrogen-driven cancers and Alzheimer’s Disease.

Copper cookware is the choice of many because it conducts heat so well. Copper cookware releases copper into the food to be eaten and usually also has nickel in the coating, which is another toxic heavy metal and can be very allergenic.

Cast iron cookware is very durable but iron is constantly leaching into the food, changing the enzymes in it. Iron can reach toxic levels in the body with regular use and becomes a pro-oxidant which causes stress, oxidation and eventually disease.

Ceramic, enamel, and glass cookware may be manufactured with lead which can give the product color uniformity. The level of lead in each product is set by the United States – FDA and California Prop 65 – Never cook with anything labeled “for decoration only.

Stainless steel cookware is made from a metal alloy consisting of mostly iron and chromium along with differing percentages of molybdenum, nickel, titanium, copper and vanadium. But even stainless steel allows other metals to leach into the foods. The principal elements in stainless that have negative effects on our health are iron, chromium and nickel.”

What to Do?

As with anything, don’t let the perfect be the enemy of the good. I can’t afford to completely replace all of my cookware overnight, and I don’t think that some of the other options are that bad compared to some other lifestyle factors (not eating vegetable oils, getting Vitamin D, etc) .

I’m slowly asking for safer cookware for birthday and Christmas gifts, and in the meantime, I’m using steel and cast iron when I have to. I do make sure to avoid non-stick and aluminum cookware completely.

    *Dr. MERCOLA ?? not medical lol. But awesome! I also found out that Longaberger’s Cookware is vitrified so it can be used on induction stoves as well as gas. Also the Mercola site has soup pots and 100% ceramic knives. All his cookware comes with a 50 year warranty like Ceramacor. The knives dont though. Oh and an 11 inch wok. 😀 I did come across some others but I will do more research before I mention them.

    Hey Wellness Mama,
    First I want to thank you for creating this blog I have been reading and using your tips and advice for the last two years since I found your site….. on the glazed ceramic cookware. There is a company named Longaberger that sells glazed ceramic I havent found anything bad about them but their prices seemed fair enough they have a catalog and I found some stuff on Amazon. ALSO Dr. Medical had the same exact line in a set give or take on of the skillets I believe…… for one hundred dollars less than xtrema. I dont know if either have have passed all the tests as their cookware but I thought I’d give a heads up. I know that I’m not the only one who is a Frugal Fran lol. But in all seriousness those are some options that I found since reading your post and I didnt know if you knew of them as well. Happy health and wellness all and God Bless 😀

    You know I believe the owner of Extrema is telling the truth that this is not nanotechnology as they started out (they don’t use original process from 2008 or so). This Extrema pot strangely has made me do tons of research and even question the nature of energy and matter, as well as various industrial processes. I think it is very safe but the pot might be more fragile than let’s say a Le Creuset as far as chipping or breaking. I will research the two you mention and also give you an interesting link about surface chemistry that is real easy to grok and get back with you next week. Thanks for responding!

      I cannot find the link I wanted to send but am researching Rockpot and will get back with you this week. Thanks for telling me about it!

        I’d love to hear what you say about the ROCK cookware too, can you keep me in the loop about that?

        I’d love to be kept in the loop about the ROCK cookware. I have a pan and love it but am wondering about the safety of it too. One annoying thing about mine is that I think it says not to use salt in it…I always season my stuff! 🙁

    I am the lady with the doubts about Extreme Cookware that E-mailed you recently. I ended up buying one of their pots and not returning it – The owner of company said they no longer use the 2008 patent and no nano technology is in this pot he claims (I don’t like nano). He did say there was 0.34% or some tiny amount of zirconium in the formula and did not specify is this was medical grade (zirconium can be radioactive). Hopefully they are conscious enough company to test for radioactivity or the source is good. I know it comes from China. Well I bought it anyway and will have to go past all that. I also bought Le Creuset and like that a whole lot better because it has a certain feel to it but takes a really long time to heat up.

    Trying to find a safe cookware set that I can afford is overwhelming for me at this point. I did find one that is affordable but I’m not sure if it is safe enough. Cuisinart 59-10R Elements 10-Piece Cookware Set says that it is PFOA/PTFE free. It is described as Nano-ceramic. I was almost convinced to purchase a stainless steel set but now I’m reading that metals leach through that too. Help!!!

    Hi Katie, I would love to know your opinion on the Emile Henry flame top line. They are much like Le Creuset in that they have many colors to choose from, but they are glazed ceramic like Xtrema and made in France. Thank you so much for your help!

      Extrema is made in China. I just bought a Greblon, made in Germany.
      I emailed their corporate communications director and he confirmed that the Greblon is made in Germany. I am trying to remove all Chinese food products from my kitchen, except glass. It is made out of the cheapest material on the planet, I feel safe they won’t try to substitute cheaper materials, which they do, with every product.

          Glass is also NOT NONSTICK. Its very hard to clean burnt foods off and over time it does stain . I had an old corningware coffee percolator that had burner stains from where coffee had dripped. It also can crack or shatter when trying to deglaze.

    May I know how heavy the ceramic skillet is – compared to cast iron one ?
    I couldn’t find any information about the weight. And as far as cast iron is a good and safe cookware, it’s too heavy for me to handle.

  9. Heather Avatar

    Thank you for this post. I was just wondering if aluminum coated in ceramic was ok in your opinion? It’s non porous and that would make a good barrier to protect from metals leeching. What do you think?
    Thank you.

      I should think that only aluminium which is in direct contact with food (particularly acidic foods) should be of concern. That is, the old non-coated aluminium pans particularly the ones that are scratched and pitted.

      Today most aluminium pans are coated in stainless steel or some other material. The aluminum is used only on the exterior surface for its superior heat-conducting property, and only a risk if somehow the coating comes off and exposes the aluminium underneath.

    Hi everybody, I just bought an enamel lightweight cast iron, what do you think about this cookware???, I’m also looking for a good skillet, good enough for frying potatoes, my children like a lot potatoes with eggs, could someone recommend a good frying pan please?????

    I was looking for some information about the harmfulness of PTFE (Teflon) and found your website.

    One thing that is actually wrong in the article you found is the information about aluminum (or aluminium as it’s called at this side of the ocean). Aluminum is definitely NOT a heavy metal. Heavy metals are always harmful, so you would like to avoid anything containing cadmium, mercury or lead (there are more, I know). Aluminum ingested in higher doses could be considered harmful, since it competes with calcium for absorption, but in general it’s a metalloid that is quite abundant in nature and is not suspected of having any biological function or specific toxicity.

    Although you might have a higher intake of aluminum when using aluminum cookware, for most people this is just a minor source; most people have a higher intake coming from drinking water and pharmaceuticals.

      I think you get it wrong, aluminium is a heavy metal and it’s toxic and harmful for your body. It gives you clouded mind. I’ve been poisoned by it (by testing my hair tissue) and took me a long time to get rid of it. Small amount of it gets into the food in cans, body absorbs it when you use antiperspirants (which is in risk of the Alzheimer’s) and many more. Therefore I wouldn’t trust these pans, because they say it’s safe.

    What utensils do you recommend to use with your ceramic cookware? I prefer ones that can be washed in the dishwasher. Thanks for all your reviews.

    I am also disheartened by chips in my Xtrema ( and I am very careful with it). I would really like to know about anyone’s experience with Emile Henry Flame top ceramic cookware made in France. Anyone??

    Many thanks!

    Katie,

    What are your thoughts on the Orgreenic brand of ceramic coated cookware?

  15. Nick Avatar

    Hi Katie,

    What do you know about schulte-ufer’s Green Life ceramic-coated stainless steel pans?

    I don’t like xtrema ware, too heavy and unsafe for use on my glass stove and quartz counters.

    Thanks,

    Nick

    I really enjoyed hearing all the information in this article about ceramic cookware and found it to be extremely helpful. I think ceramic is a great quality cookware that will last a lifetime.

    1. Nick Avatar

      Has anyone researched and/or used the schulte-ufer Green-Life ceramic coated steel ware (pots and pans)?

    2. Nick Avatar

      BTW, I’m looking into schulte-ufer’s Green Life ceramic-coated kitchen ware because I don’t like xtrema ware, it’s too heavy and unsafe for use on my glass stove and quartz counters.

      Thanks,

      Nick

    I was all ready to purchase a Xtrema Ceramic Skillet for a starter piece, but when I found out it’s made in China, that broke the idea of buying Xrtema. I will buy certain things from China, but their history of questionable quality control and questionable materials makes me VERY leery of buying ANY Ceramic products. If anyone knows of a manufacturer that makes 100% ceramic products IN THE USA, then I’ll switch to ceramic. I have NO guarantee as to what is actually in a ceramic skillet made in China. Just because one passes a “no leaching” test by an independent laboratory doesn’t mean Chinese quality control stays consistent. And besides, if it comes from China then why are pieces SO expensive? I just “chatted” with someone at Xtrema, and while I understand the need for pieces to be made in China under “exacting” manufacturing controls to make them “cheaper”, I don’t trust ANYTHING of this nature coming from China.

      Hey Bob, check and see if Xtrema are made in China or Taiwan. If Taiwan, you can usually trust them 100%.
