Giant Blue Glass Marble
XRF readings: Lead: not measured · Cadmium: 60 ppm · Arsenic: 366 ppm Verdict: Lead-free per XRF No lead detected by XRF. Cadmium present at 60 ppm, separate concern for colored glazes. Arsenic detected at 366 ppm. 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... Read more...
Antique blue milk glass small pitcher with handle: 161 ppm lead by XRF
XRF readings: Lead: 161 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 161 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...
Blue-rimmed drinking glass: 152 +/: 48 ppm lead by XRF
XRF readings: Lead: 48 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low, probably not a concern 48 ppm lead detected, below the 90 ppm children's safety threshold. At this level, most toxicologists would not flag this as actionable for typical adult use. FluoroSpec test: if it doesn't glow, the lead is not in reactive surface form. 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... Read more...
1966 Peter Pan ’45 of Rudolph the Red Nosed Reindeer: 3,777 ppm lead by XRF
XRF readings: Lead: 3,777 ppm · Cadmium: not measured · Arsenic: not measured Verdict: High, FluoroSpec test required 3,777 ppm lead detected by XRF. This item is at or above the boundary where ceramic lead can begin to behave differently under acidic conditions. FluoroSpec is the actionable test: glow = retire it, no glow = lower risk. 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:... Read more...
Department 56” Cat Christmas Tree Dish: 1,006 ppm lead by XRF
XRF readings: Lead: 1,006 ppm · Cadmium: 765 ppm · Arsenic: not measured Verdict: Elevated, likely lower risk in fired ceramic, test to confirm 1,006 ppm lead detected. Context: where on the item, food contact frequency, and whether it is fired ceramic vs. paint or soft coating matters significantly. Run FluoroSpec, glow = retire, no glow = likely lower risk. Also: 765 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... Read more...
Vintage (c. 1990?) Corelle Dish with Pink Roses & Black Trim: 3,536 ppm lead by XRF
XRF readings: Lead: 3,536 ppm · Cadmium: 100 ppm · Arsenic: not measured Verdict: High, FluoroSpec test required 3,536 ppm lead detected by XRF. This item is at or above the boundary where ceramic lead can begin to behave differently under acidic conditions. Children should not use this item. FluoroSpec is the actionable test: glow = retire it, no glow = lower risk. Also: 100 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... Read more...
XRF Test Results for Certified International Blue Glazed Ceramic Bowl (purchased at Costco c. 2017 or Later), Made in China: 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. Independent leach testing on fired ceramics in this range found no detectable lead migration, the lead is chemically bound in the glaze matrix. FluoroSpec gives the definitive surface answer: glow = reactive... Read more...

XRF Test Results for Pink Glazed Winifred & Lily Ceramic dog Food Bowl (sent in by a Lead Safe Mama reader for testing)
XRF readings: Lead: 100 ppm · Cadmium: 53 ppm · Arsenic: 0 ppm Verdict: Low-elevated: below most adult thresholds This XRF Test Results for Pink Glazed Winifred & Lily Ceramic dog Food Bowl (sent in by a Lead Safe Mama reader for testing) reads 100 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). What this XRF reading actually means → XRF measures... Read more...
