Introduction (for those new to this website):
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, her sons were acutely Lead-poisoned in 2005. Since 2009 Tamara has been using 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. Tamara’s work was featured in Consumer Reports Magazine in February of 2023.
There’s a recent TikTok video circulating all over the internet about Pyrex glassware and the differences between glassware with the “PYREX” all-caps logo vs. glassware with the “pyrex” all-lowercase logo. This video has been shared with me by dozens of Lead Safe Mama readers… so I made one in response:
I didn’t see the TikTok video but this is very clear.
And congratulations on having your work highlighted in Consumer Reports. I’ve seen some people here disparaging main stream media but I think getting some impressive nods from the people also doing good work at CR will get the word out to a broader audience.
I am unable to view the Pyrex video.
I do not use a tik token app. Is that why I can’t view it?
I hate auto correct……
I just fixed it! Try again. Thank you.
The Lead Safe Mama website says, “Video currently unavailable.”
I went on TikTok to find it, but I didn’t see it there.
Can you post it on your website for people to see it, please? (re: PYREX vs pyrex)
Hi there! I just fixed it. Please try again! Thanks.
Great video!
Oops, I tossed out my uppercase PYREX clear glass pie plates a while back. They didn’t have a painted logo, it was etched in, but I assumed vintage meant it was possibly toxic. I had that casserole dish, I am glad I got rid of that too.. better safe than sorry! Thanks for the info!
If the paint is on then outside of PYREX measuring cup is that toxic?
yes – please read this: https://tamararubin.com/2020/07/if-the-lead-is-only-on-the-outside-of-my-dish-measuring-cup-mixing-bowl-etc-why-does-it-matter-that-it-has-lead/
So what measuring cup do you recommend?
There are several suggestions on my shopping website: http://www.ShopLeadSafeMama.com
I have my eye on a Pyrex cranberry mixing bowl set. I believe it’s from the 80s or 90s. It is translucent glass with a purplish tint and has no painted markings. They look similar to a blue Pyrex custard dish that you said was safe. What do you think? Are the mixing bowls worth it?
How can you tell if the clear Pyrex has high levels of arsenic?
I think it is age-related factor – probably a consideration for items that are older than 40 years old. They are not clearly marked with age-indicating identifiers though – so I truly don’t know how an end-consumer would know (unless you could extrapolate the age because you knew they belonged to your grandmother or something along those lines.)

Hi Tamara,
I read other post and found out yoda decorated Pyrex glassware contains no lead. I am curious about if other decorated Pyrex glasswares, such as Mickey and friends in the affiliate link on Amazon (https://a.co/d/gkYwZCL ) also lead-free.
I just a few weeks ago, bought new clear glass Pyrex baking dishes, they have no paint or anything, just clear. Would you use these or should I try to return them? I thought I was making a good choice leaving nonstick and going to glass and now I’m not sure what to do.
Those should be free of toxicants (Lead, Cadmium, Mercury, Arsenic and Antimony!)
Are the clear glass PYREX baking pans also considered safe?
