When tested with an XRF instrument this Mexican glazed ceramic bowl – with bird design on the inside had the following readings on the food-surface of the bowl:
- Lead (Pb): 51,608 ppm
- Mercury (Hg): >100,000 ppm (greater than 10% Mercury in the glaze)
- Arsenic (As): 31,350 ppm
Takeaway: PLEASE avoid all Mexican pottery (especially for food use purposes) at all cost unless you know the artist and know for sure it is lead-free! Even Mexican pottery MARKED “Lead Free” may not be Lead free at all. Click here to see an example of that.
