XRF readings:
Lead: 90 ppm · Cadmium: 1500 ppm · Arsenic: 0 ppm
Verdict: Low-elevated: below most adult thresholds + High cadmium
This XRF test results for Crate & Barrel “Poetry” china pattern (Made in Great Britain): Positive for extremely high level of Lead (a common finding for decorated Crate & Barrel pieces) reads 90 ppm lead, above the 90 ppm CPSC limit for children's products. Whether the lead can actually reach food depends on whether it's locked into fired glaze (typically not bioavailable) or sitting on surface paint (typically is). Cadmium reads 1500 ppm, which is also flagged territory.
What this XRF reading actually means →
XRF measures lead presence on the surface. It does not measure whether that lead can reach a person. That distinction matters for how you should react to this number. Read the full primer.
