Lead Database

Stop using your vintage Tupperware NOW. These measuring cups are positive for 2,103 ppm Lead + 250 ppm Arsenic.
XRF readings: Lead: 2103 ppm · Cadmium: 0 ppm · Arsenic: 250 ppm Verdict: Elevated: likely lower risk in fired ceramic, test to confirm This Stop using your vintage Tupperware NOW. These measuring cups are positive for 2,103 ppm Lead + 250 ppm Arsenic. tested at 2103 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 250 ppm, worth noting on top of the lead question. What... Read more...
Harvest Hill Press mug: 10,300 ppm lead by XRF
XRF readings: Lead: 10,300 ppm · Cadmium: 404 ppm · Arsenic: not measured Verdict: Very high, avoid food contact 10,300 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. Also: 404 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... Read more...
Arsenic “Name Your Poison” Vintage Barware Glass: 96,700 ppm lead by XRF
XRF readings: Lead: 96,700 ppm · Cadmium: 3,600 ppm · Arsenic: not measured Verdict: Extreme, do not use + High cadmium 96,700 ppm lead, roughly 9x 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. NOTE: 3,600 ppm cadmium also detected, a separate and serious concern for colored glazes. There is no safe amount of lead. This number is a starting point, not a verdict on your safety.

Paint on Brand new (2019) Sneaky Pete Vaporizer Borosilicate Glass Vape Tube: 6,827 ppm lead by XRF
XRF readings: Lead: 6,827 ppm · Cadmium: 2,233 ppm · Arsenic: 807 ppm Verdict: High, FluoroSpec test required + High cadmium 6,827 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. NOTE: 2,233 ppm cadmium also detected, a separate and serious concern for colored glazes. There is no safe amount of lead. This number is a starting point, not a verdict... Read more...
Garfield “Use Your Friends Wisely” McDonald’s mug: 103,600 ppm Lead (causes brain damage) + 7,314 ppm Cadmium (causes cancer)
XRF readings: Lead: 103600 ppm · Cadmium: 7314 ppm · Arsenic: 0 ppm Verdict: Extreme: do not use + High cadmium This Garfield “Use Your Friends Wisely” McDonald’s mug: 103,600 ppm Lead (causes brain damage) + 7,314 ppm Cadmium (causes cancer) tested at 103600 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. Cadmium reads 7314 ppm, which is also flagged territory.

New post/New Video: Testing a Beyblade for Lead (Lead testing on Zinc items)
XRF readings: Lead: 600 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm Verdict: Low-elevated: below most adult thresholds This New post/New Video: Testing a Beyblade for Lead (Lead testing on Zinc items) reads 600 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).
