Please avoid vintage Tupperware. This is a kid’s 6 oz. cup. It’s positive for 876 ppm Lead, 331 ppm Cadmium, + Arsenic.
XRF readings: Lead: 876 ppm · Cadmium: 331 ppm · Arsenic: 7 ppm Verdict: Low-elevated: below most adult thresholds This Please avoid vintage Tupperware. This is a kid’s 6 oz. cup. It’s positive for 876 ppm Lead, 331 ppm Cadmium, + Arsenic. reads 876 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 331 ppm, which is also flagged territory. What... Read more...
XRF test results for pink and white glazed Gerald Henn Workshops Spongeware pottery dish (Made in Roseville, Ohio in late-1980s) — sent in by Lynn in Texas: 1,500 ppm lead by XRF
XRF readings: Lead: 1,500 ppm · Cadmium: 46 ppm · Arsenic: 33 ppm Verdict: Elevated, likely lower risk in fired ceramic, test to confirm 1,500 ppm lead by XRF. Independent leach testing on similar ceramics in this range (up to 3,000 ppm) found no detectable lead migration into food simulant, lead baked into fired glaze is chemically bound and doesn't readily dissolve. This is the key context missing from most XRF-only reporting. FluoroSpec test: if it doesn't glow, the lead is not in surface-reactive form. There is no safe amount... Read more...
