This is a glass purchased at Pottery Barn in 2022. It did test positive for trace levels of Antimony and Lead. Here’s the direct link to this glass on Pottery Barn’s website. In general, I do not like the company Pottery Barn – as they have a history of producing toxic products (a history for which they have not publicly taken any responsibility) – this includes recently-manufactured home goods with unsafe levels of Lead. To see more Pottery Barn items that we have tested and reported on here at LeadSafeMama.com, please click here.
Outside of the political considerations about this brand (and the concern for false advertising / misleading marketing – given this design is expressly sold and marketed as “Lead Free”), this particular glass (with the test results posted below in full detail) would be considered safe by all current relevant standards. But because it does test positive for trace levels of Lead, given my stand — to get all the Lead (a potent neurotoxicant, and terrible environmental pollutant) out of all consumer products moving forward (especially food-use items! ) — I would not personally choose these glasses for use in my home. But if someone served me a beverage in this glass when I was visiting their home, I would have no issue with drinking from these glasses. Full XRF test results are below. Test results are replicable, science-based and accurate.

Background updated September 2022:
Tamara Rubin is a Federal-award-winning independent advocate for consumer goods safety and a documentary filmmaker. She is also a mother of Lead-poisoned children. Tamara’s sons were acutely Lead-poisoned in August of 2005. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. Her work was also responsible for two CPSC product recalls in the summer of 2022, the Jumping Jumperoo recall (June 2022) and the Lead painted NUK baby bottle recall (July 2022) and was featured in an NPR story about Lead in consumer goods in August of 2022. Tamara uses XRF testing (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals), including Lead, Cadmium, Mercury, Antimony, and Arsenic. All test results reported on this website are science-based, accurate, and replicable. Items are tested multiple times, to confirm the test results for each component tested and reported on.

So, are you saying that 94 & 98 ppm are considered trace level amounts in this glass? I thought a score of 90 was the safe cut-off for lead. What is a safe level for antimony? I’d like to find a resource that discusses what are safe levels for any of these metals.
Thank you, Tamara!
Tamara says
Hi Carolyn,
Those levels (with the margin of error taken into account) are in the safe range for Lead (under 90 ppm – ish.) There is no regulatory standard for Antimony – however it is similarly toxic to Lead (at similar levels).

Regardless of the lead levels being low, what kills me is the product overview says they are lead free:
“Perfect for everyday use or your next dinner party, the Hammered Glassware Collection is casual yet elegant, featuring a warbled texture that brings visual interest to the table. Handmade craftsmanship and organic lines make this recycled glassware collection stand out from the rest.
Handmade of blown glass.
Lead free.
Collection includes Short & Tall Drinking Glasses, Stemless Wine Glasses, Stemless Champagne Glasses, Tumblers, Goblets, or Carafe (sold separately).
Imported.”

Hi Tamara
Can I ask if you calibrate your XRF analyzer and how often do you get this done?
Tamara says
It’s a self-calibrating instrument. I run a calibration check every time I use it. (One of the reasons this instrument type costs $35,000-$50,000 new.)

This is just so frustrating. While I love your blog and often use the information within, things like this just confuse me and make me feel very very depressed. It seems like we keep being told that glass is the surest thing in terms of safety and then you buy a standard glass like this (i.e. not vintage or anything), and its still a problem? How are we supposed to go out and buy things to use in our homes if we cant even trust the manufacturers listing (“lead free”) on a new glass item? None of us have a xrf machine and we’re also told that no home kits have the ability to properly test for lead in home items like dishware. What are we supposed to do?
We’re hosting christmas next month at our home and need to buy wine glasses and this seemingly simple task is giving me endless anxiety because of all this. I’m hearing some wineglasses contain lead too.
Tamara says
I always recommend avoiding everything from Pottery Barn (as a rule.) Here’s an article about my “no fly” list:
https://tamararubin.com/2020/02/list-of-stores-i-wont-shop-at-because-they-sold-things-with-lead-or-still-sell-things-with-lead/
Pottery Barn is a terrible company. So is Williams Sonoma and Crate and Barrel.
Inexpensive clear glass is always your best bet!
