XRF readings:
Lead: 15200 ppm · Cadmium: 400 ppm · Arsenic: 0 ppm
Verdict: Very high: avoid food contact
This Vintage Corelle Plate With Crazy Daisy Spring Blossom Green Edge: 15,200 ppm Lead (90 is unsafe for kids) + Cadmium tested at 15200 ppm lead, heavily contaminated. If any of the lead is on the painted surface, decoration, or worn area, expect bioavailable exposure with food contact, mouthing, or abrasion. Cadmium reads 400 ppm, which is also flagged territory.
