Warning (Summer 2021): Stop using NUK brand glass baby bottles until further notice — Lead paint found in exterior decorations.
XRF readings: Lead: 21900 ppm · Cadmium: 500 ppm · Arsenic: 0 ppm Verdict: Very high: avoid food contact This Warning (Summer 2021): Stop using NUK brand glass baby bottles until further notice: Lead paint found in exterior decorations. tested at 21900 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 500 ppm, which is also flagged territory.

Lead in Antiques & Christmas Lights (& Stained Glass Windows & Antique Print Trays) – a video: 90 ppm lead by XRF
XRF readings: Lead: 90 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 90 ppm lead, above the 90 ppm CPSC children's item threshold but well below levels that cause obvious alarm for adult use. Vintage items commonly have elevated surface lead from historical glazing, this is expected context, not exceptional alarm. FluoroSpec gives the definitive surface answer: glow = reactive lead present, no glow = not in accessible form. There is no safe amount of lead. This number is a starting point, not... Read more...
Denby Floral Pattern Fine China Tabletop Designs 1974, Made in Portugal: as high as 24,500 ppm Lead on the food surface: 24,500 ppm lead by XRF
XRF readings: Lead: 24,500 ppm · Cadmium: 500 ppm · Arsenic: not measured Verdict: Very high, avoid food contact 24,500 ppm lead detected.

FluoroSpec will confirm whether lead is surface-reactive. Also: 500 ppm cadmium present. There is no safe amount of lead. This number is a starting point, not a verdict on your safety. What matters is whether the lead can actually... Read more...

Dowan response to Lead Safe Mama’s detection of (trace-level) Lead in their “Lead-free” products is “ATTACK!” LOL — Read the latest!
XRF readings: Lead: 90 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm Verdict: Low-elevated: below most adult thresholds This Dowan response to Lead Safe Mama’s detection of (trace-level) Lead in their “Lead-free” products is “ATTACK!” LOL: Read the latest! 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).
