Below you will find the XRF readings for metals found for the item pictured. All readings are done multiple times to confirm the results for each component before sharing one full set of the readings for the item pictured. Results are replicable, science-based and accurate.

For some additional background about this work, please read the following links:

1. An article discussing the testing methodology used here on this website.
2. A menu with buttons for many of the different categories of information that can be found here on LeadSafeMama.com.
3. A link to my documentary feature film on childhood Lead poisoning.
4. The short video that shows you how to search this site.
5. Items you can test at home with a LeadCheck swab.
6. Items you really cannot test at home (items better tested with XRF technology)
7. A piece discussing some of the context for the concern of Lead in ceramics / dishware / pottery
8. A overview discussing why you cannot (in most cases) test dishware yourself at home.
