Response to Dr. Mercola’s Response: 83 ppm lead by XRF
XRF readings: Lead: 83 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low, probably not a concern 83 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...
Ceramcor Xtrema “Metals-Free” Saucepan Positive For Lead, Cadmium, Cobalt, Iron, Nickel, Chromium and other metals when tested with an XRF instrument
XRF readings: Lead: not measured · Cadmium: 201 ppm · Arsenic: not measured Verdict: Lead-free per XRF No lead detected by XRF. Cadmium present at 201 ppm, separate concern for colored glazes. FluoroSpec test will confirm no surface lead reactivity. Also: 201 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 reach a person. Think of tacks: a box of them in a drawer is fine, the same tacks... Read more...
Xtrema, an important point: The clay substrate had only 4 metals. This means 10 metals were detected just in the glaze: 500 ppm lead by XRF
XRF readings: Lead: 500 ppm · Cadmium: 201 ppm · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 500 ppm lead, above the 90 ppm CPSC children's item threshold but 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. Also: 201 ppm cadmium present. There is no safe... Read more...

KitchenAid Mixer Attachments (c. 2014): As high as 2,434 ppm Lead (90 ppm Lead is unsafe in items intended for use by kids): 2,434 ppm lead by XRF
XRF readings: Lead: 2,434 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Elevated, keep away from children regardless 2,434 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. 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... Read more...

Corelle: Are your vintage dishes safe for use with food? Probably not: 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...
Target Threshold Small Green “Joy” Stoneware Dish: 255 ppm lead by XRF
XRF readings: Lead: 255 ppm · Cadmium: not measured · Arsenic: not measured Verdict: Low-elevated, below most adult thresholds 255 ppm lead, above the 90 ppm CPSC children's item threshold but well below levels that cause obvious alarm for adult use. For a children's item this is already over the regulatory limit.
