In discussing the issue of the Xtrema / Ceramcor pans with my husband tonight, I showed him my three sets of readings that I wrote up for my post from last August (August 2018 – the post with the full readings from all components on one example pan [all of which were consistent with the test results for the many other Xtrema pans I have tested].)
Because my posts are so information-dense (sorry about that!), we realized that an important point was likely buried too far down in that August post for people to easily understand the implications.
Here’s the important point:
With this particular reading set I was able to test the substrate of the pan – due to the fact that the pan was in pieces, having broken in shipping. As a result, I took the opportunity with this pan to test the clay substrate (unglazed base) which had been exposed by the breakage; it was positive for only 4 metals (Lead, Zinc, Iron and Bismuth). This means the other ten metals detected are all only in the glaze.
In testing the bare (unglazed) ceramic side of the pan, I recorded the following set of XRF readings:
Cross Section of Pan (Substrate: beige/pink ceramic base from broken side of pan)
- Lead (Pb): 25 +/- 12 ppm
- Zinc (Zn): 80 +/- 21 ppm
- Iron (Fe): 3,369 +/- 255 ppm
- Bismuth (Bi): 153 +/- 17 ppm
This means that – by deductive reasoning – most of the metals detected in the three other areas tested (on the food surface, inside lid and bottom of the pan) are in fact additives in the glazes of the pan. In Consumer Goods mode, the XRF detected a total of fourteen metals on the glazed surfaces of the pan — 10 more than were found in the substrate.
- Bismuth – in substrate – at similarly low levels to those found in the glaze. [153 ppm vs.314 ppm]
- Iron – in substrate (at much lower levels than in the glaze) [3,369 ppm vs. 21,400 ppm]
- Lead – in substrate (at much lower levels than in the glaze) [25 ppm vs. 7,258 ppm]
- Zinc – in substrate (at much lower levels than in the glaze) [80 ppm vs. 5,263 ppm]
This finding contradicts Xtrema’s assertions that the metals are not additives to the product (several of their claims assert their products have no added metals — “just the metals ‘naturally found in the clay'”).
13 of the metals found in the glaze either were not present in the substrate, or had levels in the glaze that were significantly higher than the level found in the substrate. These facts taken together indicate they are most likely added constituents of the glaze – considering their presence at all, and their higher concentrations (especially for the metals that had at least one reading with concentrations of over 500 ppm).
These metals are commonly added to glazes as colorants or stabilizers for colorants. The Lead and Cadmium were found at higher concentrations in the white and red of the bottom label and the other metals were mostly found in higher concentrations in the black elements of the surface of the pans.
- Barium – over 500 ppm
- Bismuth – trace – not likely an additive
- Cadmium – over 500 ppm
- Chromium – over 500 ppm
- Cobalt – over 500 ppm
- Iron – over 500 ppm
- Lead – over 500 ppm
- Manganese – over 500 ppm
- Nickel – over 500 ppm
- Selenium – trace – not likely an additive
- Tin – trace – not likely an additive
- Titanium– over 500 ppm
- Vanadium – over 500 ppm
- Zinc – over 500 ppm
To recap (the 8/2018 post):
The glazed sections of the pans had the following readings:
Interior (food surface) of the pan:
- Lead (Pb): 74 +/- 15 ppm
- Barium (Ba): 597 +/- 55 ppm
- Chromium (Cr): 12,900 +/- 800 ppm
- Zinc (Zn): 4,879 +/- 184 ppm
- Nickel (Ni): 2,417 +/- 163 ppm
- Iron (Fe): 19,100 +/- 700 ppm
- Bismuth (Bi): 106 +/- 18 ppm
- Cobalt (Co): 9,376 +/- 391 ppm
- Manganese (Mn): 1,466 +/- 317 ppm
Interior (food surface) of lid:
- Lead (Pb): 120 +/- 18 ppm
- Barium (Ba): 453 +/- 55 ppm
- Chromium (Cr): 9,744 +/- 419 ppm
- Zinc (Zn): 4,869 +/- 188 ppm
- Nickel (Ni): 2,326 +/- 165 ppm
- Iron (Fe): 21,400 +/- 700 ppm
- Bismuth (Bi): 136 +/- 20 ppm
- Vanadium (V): 1,069 +/- 144 ppm
- Titanium (Ti): 2161 +/- 236 ppm
- Cobalt (Co): 9,506 +/- 405 ppm
- Manganese (Mn): 1,012 +/- 321 ppm
Center of Bottom of Pan :
- Lead (Pb): 7,258 +/- 201 ppm
- Cadmium (Cd): 567 +/- 28 ppm
- Barium (Ba): 688 +/- 67 ppm
- Selinium (Se): 358 +/- 35 ppm
- Tin (Sn): 214-+/- 21 ppm
- Zinc (Zn): 5,263 +/- 206 ppm
- Nickel (Ni): 776 +/- 111
- Iron (Fe): 6,036 +/- 374
- Bismuth (Bi): 314 +/- 39
- Vanadium (V): 9,169 +/- 636
- Titanium (Ti): 1,773 +/- 351
- Cobalt (Co): 3,784 +/- 251
- Manganese (Mn): 957 +/- 386

For Context: My original posts with my findings of metals in Xtrema products:
- Here is the original post about these Ceramcor pans having Lead from June 9, 2017 – there are more than 140 comments and it is quite entertaining so you might like to sit down in a cozy spot with a glass of wine to read that one.
- Here’s a follow up post from August 2018 where I shared the full metals breakdown for these Xtrema Ceramcor Mercola pots and pans.
As always, please let me know if you have any questions.
Thank you for reading and for sharing my posts.

Can I ask what brand of cookware you recommend or use yourself? I just bought Xtrema, but have not unboxed it yet. I can still return it.
I too would like to know the recommended safe cookware and what you yourself use daily/often.
Dena Walters says
I asked the question 6 months ago and still no response. Honestly, I don’t know if this site is being monitored by the women who set it up
I have over 5,000 comments here and thousands of comments on social media. More than 1.9 MILLION unique individuals read my website in the 2019 calendar year alone. Unfortunately I cannot answer all of the questions, as I am also a mother of disabled children and in spite of spending nearly every available waking moment working – I still cannot get to all the answers.
When you comment here as you have done (and I see this comment on the back end of my website) I have no idea what the original question is that you are referring to so then also have to go look it up in order to respond… I will answer more questions in these comment threads as soon as I have a moment.
There is a search bar on the site. I have written more than 2,100 posts and pages. The answer to your question has probably already been written – as I try to write up new blog posts with answers to frequently asked questions. So please do also use the search bar that is on every page (with key words) and the keyword tags at the top of every page to find more information about the subject you are asking about. For example enter “Pots & Pans” to see all of my posts related to pots and pans OR click the tab at the top. If you are looking for products I recommend – go to the “SHOP” tab in the menubar on the header of each website and look at the “Amazon Store” or the “Safer Choices” post series.
Thank you for your patience.
Wait, so you had time to write ALL of that but not answer the question in a single word? Just wanted to say that, not sure if other people are thinking the same thing.
Please do use the search bar as described above – or the video in the right-hand margin that shows how to use the website.
Hello again Jennifer –

And Jennifer – here’s my overview post on Pots & Pans (this comes up if you put “Pots and Pans” in the search bar – which is on the top of every page):
Finally Jennifer – you might be interested in checking out the Shop Lead Safe Mama website – which is linked at the top of every page of the website as well:
Hi there I have extrema pots and pans and had high uranium in hair test for me and my daughter. We are doing more tests as I know hair is not conclusive but since we both had it in our results and I sent the samples in about a month apart I’m justifiably concerned. Have you tested for radioactive elements? Have you cooked food in the pot and tested the food to see what leaches out? I spent a lot of money on these pots omg!!!
Alexander M Bergstrom says
Xtrema – the most tested and healthies cookware made in the world.
Hayley Le says
Both of my kids tested high on Uranium (off the chart high) on hair tests too and the tests were done before we bought Xtrema set and repeated 2 years after we used Xtrema set. So it was not from Xtrema. Then I thought it might come from the water we drank so we switched to only cooking and drinking bottled spring water. After 2 yrs we are still super high on Uranium. Now I’m thinking it may come from the food source we eat. Are you eating a lot of root veggies? Are you located in Southern California?
If you like to talk more, here is my email firstname.lastname@example.org.
i just emailed you hayley- thanks for the reply! would love to connect
High uranium is often caused by radon in your house
