This Spode brand yellow “Delamere Blue” pattern china (Made in England) was positive for lead when tested with an XRF instrument. It came in at 47,500 ppm lead (+/- 1,500 ppm).
- The amount of lead that is considered unsafe in a newly manufactured item intended for children is 90 ppm in the coating or 100 ppm in the substrate.
- Dishware is not regulated for total lead content as detectable with an XRF.
- Most vintage dishware was also not regulated for leach testing standards (or other standards) at the time of manufacture (depending on the age).
- There are documented cases of both children and adults being poisoned from eating off of high lead vintage/ antique dishware.
- Most “Made in England” vintage china that I have tested has been similarly high lead (in the range of 40,000 to 50,000 ppm and sometimes higher.)
- To be on the safe side, I advocate for avoiding vintage china if at all possible (unless you have had it tested and found it to be truly lead free.)
This dish was “Non-Detect” (negative) for mercury (Hg), cadmium (Cd), and arsenic (As).
