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.”

Daughter using very heavy drinking glasses with square cut blocks to top. 12 oz or more bought in outlet popular kitchen chain years ago. When hit rings. She uses daily and in dishwasher. She bre astfeeds and told her not to use. Baby has low level lead in blood! Wth. Is Libbey drinking glasses all lead free as they say? I am sick frim worrying about manufacturing in China and lead and other contaminants! Google: lead in plastic toys. Want to cry! Fisher Price, thousands of toys with lead. Bought Lego blocks, new pushtoy to learn how to walk? God help us. I am huge environmentalist!
Hello! I work at a Starbucks and am trying to be lead-conscious. What about the matte green studded tumblers? Or the plastic, clear starbucks branded tumblers? Is plastic a concern?
hi Kaitlyn, The plastic ones do not test positive for Lead. Here’s one example: https://tamararubin.com/2018/11/does-the-2018-starbucks-reusable-holiday-cup-test-positive-for-any-nasties/
I haven’t tested the green studded ones – I am not familiar with those. I will keep an eye out for them.

I see that this post is dated 2017. Have you tested Starbucks glass recycled cups more recently? Wondering how the 2023 glass cups fare. I would prefer to drink out of glass vs plastic, but not if the glass contains lead! Thank you!
Does lead leach from the glass when filled?
I don’t think this has been studied for glassware with this level of Lead.
