When tested with an XRF instrument this glass Pyrex measuring cup had the following readings:
- Lead (Pb): Non-Detect/ND [Negative]
- Cadmium (Cd): 326 ppm [in the red writing on the outside of the glass.]
Sorry – I don’t have any more information about the model number or year of manufacture on this one!
Cadmium is a known possible carcinogen and does not belong in our cookware. To read more about the concern for Cadmium (Cd) in food preparation equipment, Click Here.
There are only two relevant standards for total Cadmium content. In Washinton State something is considered illegal if it has more than 40 ppm Cadmium. In Denmark something is considered unsafe or illegal if it is 75 ppm Cadmium or higher.

As always, thank you for reading and for sharing my posts.
Please let me know if you have any questions.
Is there an alternative Pyrex type glass measuring cup I can purchase to avoid heavy metals?

The Pyrex measuring cups at Crate & Barrel have black paint:
Any plans to test those?
I only test what my readers send me right now, and no one has sent me one of those. This work is a collaborative effort with my readers. Thank you for the idea!

If the food never touches the paint, since the paint is on the outside, is it still a concern?
The handle is paint free too.
I am curious about this too. *bump*

I’ve been using the “100-year anniversary” Pyrex measuring cups as my tea mug for the past year and was wondering whether there is cadmium/lead exposure (even though the paint markers are only on the outside of the glass)?
Also curious about this
I am considering replacing my Woodlands Corelle dishes with some Lenox I have stored. Is this a good idea or is it problematic too? Have you tested these? We grew up on Corelle & Pyrex. I guess a chat with my Dr. is next. Thank you for all your efforts with educating the public.

How do you clean dishes that have been exposed to lead contaminated dishes that were cleaned in a dishwasher?
