XRF test results for New (2023) Dowan-brand yellow plate (Made in China)
XRF readings: Lead: data not on file · Cadmium: 75 ppm · Arsenic: 0 ppm Verdict: Lead-free per XRF This XRF test results for New (2023) Dowan-brand yellow plate (Made in China) carries a Lead-free per XRF verdict in the EverythingLead dataset. Numeric XRF data is not on file for this entry. 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 react to this number. Read the... Read more...
XRF test results for Franconia Silver Thistle pattern (K & A Krautheim, Selb Bavaria Germany) china dish sent in by Cindy in Texas: 90 ppm lead by XRF
XRF readings: Lead: 90 ppm · Cadmium: 96 ppm · Arsenic: 29 ppm 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...
XRF test results for New (2023) Dowan-brand red plate with white geometric pattern (Made in China)
XRF readings: Lead: not measured · Cadmium: 75 ppm · Arsenic: not measured Verdict: Lead-free per XRF No lead detected by XRF. Cadmium present at 75 ppm, separate concern for colored glazes. 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... Read more...
XRF test results for white glazed Roscher Bone China dish (Made in China) — sent in by Savannah in Colorado: 10,000 ppm lead by XRF
XRF readings: Lead: 10,000 ppm · Cadmium: 300 ppm · Arsenic: 100 ppm Verdict: Very high, avoid food contact 10,000 ppm lead detected. While lead in fired ceramic glaze is generally tightly bound, 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. Also: 300 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... Read more...

Franciscan Desert Rose Earthenware China — c. 1941, Made in USA: 122,200 ppm Lead! (90 ppm is unsafe in kids’ items)
XRF readings: Lead: 122200 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm Verdict: Extreme: do not use This Franciscan Desert Rose Earthenware China — c. 1941, Made in USA: 122,200 ppm Lead! (90 ppm is unsafe in kids’ items) tested at 122200 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.

Green Floral Denby Pattern, Made in England (sent in by Claire in MO): 108,000 ppm lead by XRF
XRF readings: Lead: 108,000 ppm · Cadmium: 30 ppm · Arsenic: 315 ppm Verdict: Extreme, do not use 108,000 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...
Tested for a Lead Safe Mama Instagram follower, Franciscan “Picnic” pattern dish, Made in USA: 108,300 ppm Lead on surface (not safe for use with food)

Soil sent in by a Lead Safe Mama reader from Kansas (XRF test results, May 2023)
XRF readings: Lead: 200 ppm · Cadmium: 28 ppm · Arsenic: 0 ppm Verdict: Low-elevated: below most adult thresholds This Soil sent in by a Lead Safe Mama reader from Kansas (XRF test results, May 2023) reads 200 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 lead presence on the surface. It does... Read more...
Last year I called Williams Sonoma out, yet again, for making & selling Lead-contaminated dishes. Their “solution” for 2023? Just slap a big ol’ sticker on the back.
