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.

    I bought the Xtrema cookware about 3 years ago. I saw it on Dr. Mercola’s website. But I bought a set directly from Ceramcor for $399 because I love the idea of the stuff, but it is not at all durable. It chips very easily with just normal use. It is made in China. I have corning ware and pyrex that belonged to my grandmother that I still use. I am now a grandmother myself so the pieces I have are quite old. Like I said love the idea of Xtrema but not happy with its durability. So for the cost I was very disappointed.

    I see a lot of great comments about cast iron etc. for the stove and oven, but what about baking? Are there any specific kinds of baking sheets and cookie sheets I should get? Most are aluminum and its really hard to find stainless steel ones around. Also, what do you think about Silpats?
    Thanks!

    I’ve begun to try baking grain-free breads at home but have had mixed results with our Pyrex glass loaf pan. I read that it’s because it’s too big, and the ideal size loaf pan for grain-free breads is 7.5 x 3.5 inches. Unfortunately I haven’t come across any ceramic, glass or stone loaf pans marked that size and the only ones listed are aluminum. Do you have a recommendation on a loaf pan for grain-free breads? Thanks!

    Hi Katie, great website! What do you think about the safety ofMasterclad cookware being sold at Costco? They are made of ceramic and titanium material called Ti-3 which is fused and

      Masterclad is made with the generic teflon. The company even admitted they used it but did not know that it was generic Teflon, Teflon is a specific brand of non-stick substance.

    Hi Katie and all! What do you (and WM community) think of clay cookware such as la chamba?

    Katie or anyone who thinks they know,

    I’ve been slowly redoing my kitchen too. My family including our 18 month old are all vegetarians, other than when we do eat salmon sometimes but that’s it. I was thinking of going to cast iron to help make sure we have enough iron since we don’t eat meat. Both my daughters and my iron levels when tested have been good, on the low side of good so not bad considering we get our iron in our plant pased food. Would you think that cooking primarily in cast iron would be not as healthy still with veggies and mix up what you cook in or stear clear of cast iron for better options?
    Thank you!

    Purchased Xtrema cookware from Mercola several years ago. On sale and free shipping to Canada at that time. It did take some time to get used to them as they take time to heat up and then hold the heat. Once over the learning curve you will like them.

    Ah cookware. I’m now doing the same; asking for new stuff for Christmas and birthdays.

    Katie, I have a unrelated question. Do you have any tips or advice on how to get a 6 month old to take FCLO without spitting it out. We just started solids….

    Thank you for this info. Really appreciate so much info all in one place – makes it very easy to understand. My question is about the more affordable ceramic coated pans I see at TJMAXX, Marshalls, etc. Are they safe? Many of them that I have seen are ‘heavy gauge aluminum’ but are coated with ceramic coating. is this a safer alternative until I can afford a better pan? Or, can you advise what to look for in stores like these? what to avoid, etc? new at this, your input is very much appreciated :). thanks!

    So we use our aluminum coated pan in our bread machine to make our dough, do you think that the nastiness seeps a little less into our bread bc the machine doesn’t get to as high a temperature as baking bread???? And have you found an alternative for this? Thanks, Nicole’

      So do I. I rarely use high heat except to boil water and never deep fry. I usually prefer slow cooking.

  12. Justine Avatar

    Yes, I’m concerned about durability, too. I bought an Extrema pan and have used it only a few times, but it already has a couple small chips. It’s disheartening when a piece costs so much.

    I use Saladmaster cookware. It’s a bit pricey but it cooks well, cleans well, you don’t need much oil or any at all depending on what you cook, they stack well in the cupboard, you cook with less water and the food tastes wonderful, and they are made of titanium so they are very safe to use.

    I enjoyed your article and think ceramic is good stuff. I cook with Ultra Stahl which is food grade stainless with titanium. It comes with lids that have a built in thermometer and act like a pressure cooking seal so foods cook quickly and with less nutrient loss. I first heard about this system on Underground Wellness (Sean is a big fan). They’re great.

    Hi Katie,

    I’d love to know what you think of Dr. Mercola’s cookware.

    Thanks!

        I bought an complete set of Xtrema cookware through Dr Mercola – pans, pots, tea set with all the utensils included. Cost me $000’s.

        I gave them all away… except the broken one.

        They weighed a lot, I could not pick up with one hand. they chipped. Food stuck to them even when I used lots of oil. The bases of a couple of the pots stained.

        This was 4 years ago – perhaps the product has improved.

        When I first had problems with the product I got in touch with Xtrema manufacturers and got absolutely and utterly no satisfaction. I was told I could send the product back and they would look at it. Great, I live in Australia, the pot weighed 3 kgs without the lid and the postage was $54.00.

        I would not buy again under anyone’s recommendation.

    Dear Katie,
    I read your article about safer cookware, and I do have a question about enamelware. I have purchased a few pieces from Amazon and they mostly are made in the usa, and felt pretty safe with the kitchen addition. How can we tell if there is lead in the coating though? They are speckled, like the old timers used for a hundred years, and the amish community, but newly made, I think the old antique stuff has lead in it, but was curious where that information could be found? Thanks

    We use le creuset as well, made in France version. They have a version made in China but I am not sure if the materials are the same ( 1/3 less $ – I believe you get what you pay for.) I use them for high heat and low heat. The enamel coating is slightly stained but no sign of thinning out. I guess no material last forever but I would think it depends on the rate it leeches out. Does anyone have le creuset’s from many years ago? I’m curious to hear how they held up and if the iron is coming through.

      Don’t know how old this post is; I just stumbled upon the thread. I have been using le creuset pots for 19 years – they are the original flame orange colour! After use, I clean them with baking soda and a little water, and the cooking surface still looks brand new. I find that stainless steel utensils will mark the cooking surface but baking soda will remove most of those too. I can cook vegetables without using any oil or fat and nothing ever sticks. These pots were the best investment I ever made
