When tested with an XRF instrument this newer Portmeirion Eden Fruits pattern mug (sent to me by a reader in Canada) had the following readings:
On a part with primarily green glaze:
- Lead (Pb): 197 +/- 22 ppm
- Arsenic (As): Non-Detect / Negative
- Cadmium (Cd): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Antimony (Sb): Non-Detect / Negative
- Barium (Ba): 326 +/- 57 ppm
- Chromium (Cr): 11,300 +/- 800 ppm
- Selenium (Se): Non-Detect / Negative
On a part with primarily red glaze:
- Lead (Pb): 187 +/- 35 ppm
- Cadmium (Cd): 223 +/- 31 ppm
- Arsenic (As): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Antimony (Sb): Non-Detect / Negative
- Barium (Ba): 3,389 +/- 315 ppm
- Chromium (Cr): 2,154 +/- 207 ppm
- Selenium (Se): 263 +/- 33 ppm
On a part with just the white base glaze:
- Lead (Pb): 200 +/- 21 ppm
- Arsenic (As): Non-Detect / Negative
- Cadmium (Cd): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Antimony (Sb): Non-Detect / Negative
- Barium (Ba): 548 +/- 55 ppm
- Chromium (Cr): Non-Detect / Negative
- Selenium (Se): Non-Detect / Negative
PLEASE NOTE:
Most Portmeirion pieces I have tested have been very high Lead, even those made fairly recently – in the past 10 or 20 years. Click here to see more Portmeirion pieces I have tested.
All tests were done for a minimum of 30 seconds each – using a freshly calibrated Niton XRF instrument (an XL3T XRF testing in “consumer goods” mode). Tests were repeated multiple times on each component to confirm the results. All test results reported on this blog are science-based, accurate and replicable.

Thank you for reading and for sharing my posts.
As always, please let me know if you have any questions!

Hi Tamara, are you still receiving items to test? I have 2 Portmeirion bowls that have a similar bottom stamp to this one, except mine say “made in England” on the bottom. I assumed they were safe since they were made in the 2000s and not the 70s, but this post makes me think that they’re not.
