The Starbucks Coffee Brand slightly green tinted tumbler / glass pictured here had the following readings when tested with an XRF instrument:
- Lead (Pb): 1,732 +/- 96 ppm
- Mercury (Hg): Negative/Non-Detect (ND)
- Arsenic (As): Negative/Non-Detect (ND)
- Cadmium (Cd): Negative/Non-Detect (ND)
The amount of lead that is considered toxic in the substrate of an item manufactured today as intended for use by children is anything 100 ppm lead or higher. Dishes and glassware are not generally regulated for lead levels as detectable with an XRF because they are not considered to be “items intended for use by children.”
As always, please let me know if you have any questions.
