XRF Test Results for Noritake Elysian Pattern — c. 1930s (Made in Japan): 100 ppm lead by XRF
XRF readings: Lead: 100 ppm · Cadmium: 40 ppm · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 100 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...
Brown glass tincture bottle (30 ml, YB Q84)
XRF readings: Lead: not measured · Cadmium: 16 ppm · Arsenic: not measured Verdict: Lead-free per XRF No lead detected by XRF. FluoroSpec test will confirm no surface lead reactivity. 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 reach a person. Think of tacks: a box of them in a drawer is fine, the same tacks loose on the kitchen floor are not. Lead locked in a stable fired glaze is... Read more...

Ask Tamara: Do Starbucks mugs have high levels of Lead: 63,549 ppm lead by XRF
XRF readings: Lead: 63,549 ppm · Cadmium: 1,037 ppm · Arsenic: 496 ppm Verdict: Extreme, do not use + High cadmium 63,549 ppm lead, roughly 6x the CPSC 90 ppm children's limit. At this concentration, even fired ceramic glaze carries leaching risk under acidic food conditions. No food contact under any circumstances. FluoroSpec will glow. NOTE: 1,037 ppm cadmium also detected, a separate and serious concern for colored glazes. There is no safe amount of lead. This number is a starting point, not a verdict on your safety.
