20+ year old Pyrex® measuring cup.
Purchased new c. 1994
When tested with an XRF instrument the red markings on the outside of this cup were positive for Lead at the following level:
- Lead (Pb): 6,253 ppm
For context: the amount of lead that is considered toxic in an item intended to be used by children is anything 90 ppm or higher in the paint or coating (dishware is not regulated in the same way for the presence of Lead).
While it can be argued that it is “only” on the exterior and thus “non-leaching”, this is a very high amount of Lead — especially considering it is both a relatively modern item, and one intended for heavy/daily use in household food preparation activities. [I would also point out that the user – whether adult or child – can be reasonably expected to come into frequent direct contact with the painted markings in normal usage.]
Tamara, how can I tell if my Pyrex® glass measuring cup has lead or cadmium?
If you would like to make an educated guess as to whether or not a particular Pyrex® glass measuring cup may have Lead (Pb) or Cadmium (Cd) in the writing on the outside, your best option is to compare the typeface of the writing to the examples here on this site. If your cup’s typeface/”font” is the same style and color as one pictured, it is likely of the same vintage, and will also likely have similar Lead (Pb) and Cadmium (Cd) levels as this typical example.
