Pyrex Glass Measuring Cup: Positive for 326 ppm Cadmium in the Red Exterior Writing


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!
