Test results reported on this website are science-based, accurate, and replicable. All tests were done using an XRF instrument reading for metals in “consumer goods mode.” Additional metals not detected by the instrument are not listed above (some of the metals non detected are listed to help make it clear to the reader that these specific metals were not present in this item.) Tests were done for a minimum of 60 seconds each unless otherwise noted, and were repeated multiple times on each component to confirm the levels reported.
As always, thank you for reading and for sharing my posts.

Ugh! Just purchased a complete set of style house china…it is the Shannon design white on white with a silver edge. Please let me know if the lead reading is emanating from the porceline or from the decorative embellishment. I have two small boys ages 9 and 10…I would be so grateful for your input!
Hi Cathryn,
On vintage china of this age, design and style – I would definitely have concerns that it might leach.
