Black Sunbeam Crock-Pot Brand Ceramic Liner: 158 ppm lead by XRF
XRF readings: Lead: 158 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 158 ppm lead, above the 90 ppm CPSC children's item threshold but well below levels that cause obvious alarm for adult use. 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 lead present, no glow = not in accessible form. There is no safe amount of lead. This... Read more...
Silver Bordered Vintage China Mug / Tea Cup: 104,700 ppm lead by XRF
XRF readings: Lead: 104,700 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Extreme, do not use 104,700 ppm lead, roughly 10x 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. 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... Read more...

Vintage Corelle Livingware Spring Blossom Green Crazy Daisy Mug: 31,700 ppm Lead [90 is unsafe for kids]
XRF readings: Lead: 31700 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm Verdict: Very high: avoid food contact This Vintage Corelle Livingware Spring Blossom Green Crazy Daisy Mug: 31,700 ppm Lead [90 is unsafe for kids] tested at 31700 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. What this XRF reading actually means → XRF measures lead presence on the surface. It does not measure whether that lead can reach... Read more...
Vintage “You Are The Sunshine” Ceramic Mug: 3,151 ppm lead by XRF
XRF readings: Lead: 3,151 ppm · Cadmium: 571 ppm · Arsenic: 948 ppm Verdict: High, FluoroSpec test required 3,151 ppm lead detected by XRF. Independent leach testing on ceramics up to 3,000 ppm has not found significant lead migration, above that threshold the picture is less clear. 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. Also: 571 ppm cadmium present. There is no safe amount... Read more...
Vintage Ziggy Mug: 33,800 ppm lead by XRF
XRF readings: Lead: 33,800 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Very high, avoid food contact 33,800 ppm lead detected. at this concentration leaching into acidic foods (tomato, citrus, vinegar) becomes a realistic concern even in well-fired ware. FluoroSpec will confirm whether lead is surface-reactive. 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,... Read more...
y. 2000 Starbucks Coffee “City Mug” Collector Series: 3,157 ppm Lead (>90 is unsafe for kids) + 496 ppm Arsenic too!
XRF readings: Lead: 3157 ppm · Cadmium: 0 ppm · Arsenic: 496 ppm Verdict: High: FluoroSpec test required This y. 2000 Starbucks Coffee “City Mug” Collector Series: 3,157 ppm Lead (>90 is unsafe for kids) + 496 ppm Arsenic too! tested at 3157 ppm lead, significantly elevated. The bioavailability question (can this lead reach a person?) depends on whether the lead is locked into a fired matrix or sitting on a painted surface. Arsenic reads 496 ppm, worth noting on top of the lead question. What this XRF reading actually... Read more...
Newer” Made In Sweden Brio Train: 10 ppm lead by XRF
XRF readings: Lead: 10 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low, probably not a concern 10 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...
