Corningware (c. 1985-1990) Pastel Bouquet Pattern Oven Casserole: 20,400 ppm Lead + 205 ppm Cadmium

As expected, the exterior decorative painted flowers on this vintage Pastel Bouquet pattern Corningware casserole was positive for high levels of Lead when tested with an XRF instrument.

Here’s a link to a post on a blog that helps to date many of the Corningware patterns.

Here’s the XRF test results for the exterior design on the piece pictured here:

Scope Focused on Blue Flower:

  • Lead (Pb): 17,900 +/- 400 ppm
  • Cadmium (Cd): 155 +/- 15 ppm

  • Bromine (Br): 206 +/- 10 ppm
  • Zinc (Zn): 9,332 +/- 251 ppm
  • Iron (Fe): 291 +/- 101 ppm
  • Vanadium (V): 253 +/- 104 ppm
  • Titanium (Ti): 19,700 +/- 700 ppm

For context: In 2018, the amount of Lead that is considered unsafe on a newly manufactured item intended for use by children is anything 90 ppm Lead or higher in the paint or coating or 100 ppm Lead or higher in the substrate.

While no one has done any studies as to the health impact of Leaded glazes and paints on the exterior of food-use products like this (because no business or industry benefits from such a study), as a mother of lead poisoned children I personally would not have ANYTHING like this in my home and I especially would not use it for any kind of food preparation or food storage. I would give this a “Grade D” (only sparing this from a “Grade F” because the Lead is not on the actual food surface!)

There are a LOT of terrific lead-free choices for casserole dishes out there. Check out THIS LINK to start.

Thank you for reading and for sharing my posts.
