XRF readings:
Lead: 122900 ppm · Cadmium: 5200 ppm · Arsenic: 0 ppm
Verdict: Extreme: do not use + High cadmium
This 1983 Pizza Hut Care Bear “Grumpy Bear” glass: 122,900 ppm Lead when tested with an XRF instrument (90 ppm is unsafe: did you have these?) tested at 122900 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 5200 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.
