When tested with an XRF instrument, the readings on the mug picture here are as follows
- Lead (Pb): 37 +/- 11 ppm
- Mercury (Hg): Non-Detect / Negative
- Cadmium (Cd): Non-Detect / Negative
- Arsenic (As): Non-Detect / Negative
- Barium (Ba): 91 +/- 41 ppm
- Antimony (Sb): Non-Detect / Negative
- Selenium (Se): Non-Detect / Negative
- Iron (Fe): 1,990 +/- 196 ppm
- Bismuth (Bi): 49 +/- 11 ppm
- Vanadium (V): 149 +/- 26 ppm
- Titanium (Ti): 469 +/- 48 ppm
The XRF reading on the logo on the bottom was positive for the following elements and levels:
- Lead (Pb): 30 +/- 12 ppm
- Copper (Cu): 101 +/- 39 ppm
- Iron (Fe): 1,184 +/- 182 ppm
- Bismuth (Bi): 31 +/- 11 ppm
- Vanadium (V): 666 +/- 177 ppm
- Titanium (Ti): 2,322 +/- 356 ppm
These levels are considered safe by all standards.
For context: levels in the 90 ppm range or below are considered TRACE lead, meaning a very small amount.
When this amount of lead is found in a consumer good that is made of ceramic, it is generally a contaminant in the clay or glaze and is not usually an added ingredient that is intentionally part of the manufacturing process.

In general I am comfortable feeding my children off of Ikea dishware. A lot of Ikea dishware is, in fact, Lead-free and we have a few Lead-free Ikea dishes in our home. Newly made Ikea that I have been testing in the past year or so has all either been Lead-free or Lead-safe (in the range of 90 ppm lower.)
Please note: If I was visiting and you served me food on newer (post 2010) Ikea dishes I would not be concerned about lead in the dishes.
Lead at this level (below 90 ppm in a newly manufactured piece) is also very unlikely to leach or to cause any harm to humans, especially given the Ikea pottery is mass manufactured and high fired.
I am much more concerned about so much of the vintage pottery I have tested that often has lead levels in the THOUSANDS of parts per million (or even the tens of thousands of parts per million.).
As always, thank you for reading and please let me know if you have any questions.
