XRF Test Results for Cavalier Ironstone Royal China (Made in U.S.A.) — Ceramic Dish
XRF readings: Lead: 100 ppm · Cadmium: 2000 ppm · Arsenic: 0 ppm Verdict: Low-elevated: below most adult thresholds + High cadmium This XRF Test Results for Cavalier Ironstone Royal China (Made in U.S.A.) — Ceramic Dish 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). Cadmium reads 2000 ppm, which is also flagged territory. What this XRF reading actually means... Read more...
Threshold by Target (Made in Portugal) glazed terracotta appetizer dish: 4,000 ppm lead by XRF
XRF readings: Lead: 4,000 ppm · Cadmium: not measured · Arsenic: not measured Verdict: High, FluoroSpec test required 4,000 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. Children should not use this item. FluoroSpec is the actionable test: glow = retire it, no glow = lower risk. There is no safe... Read more...

Children should not handle this item. 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... Read more...
Cast Aluminum Strikes Again (I have never tested a plug-in waffle iron that was negative for Lead): 6 ppm lead by XRF
XRF readings: Lead: 6 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low, probably not a concern 6 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...
#SaferChoices: Which Water Bottles & Sippy Cups are Lead-Free?
XRF readings: Lead: 300000 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm Verdict: Extreme: do not use This #SaferChoices: Which Water Bottles & Sippy Cups are Lead-Free? tested at 300000 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 a person. That distinction matters for how you should... Read more...
Tamara’s Toxic Dishes Guide: “Do my dishes have Lead?” Read this article to check if YOUR china has Lead: 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. 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...
