As expected, the exterior decorative pink painted tulip pattern on this vintage Rose Marie Tulip Pattern Corning casserole was positive for high levels of lead when tested with an XRF instrument.

Here’s the XRF test results for the exterior design on this exact piece:
- Lead (Pb): 8,164 +/- 674 ppm
- Cadmium (Cd): 165 +/- 50 ppm
- Mercury (Hg): Negative/ Non-Detect
- Arsenic (As): Negative/ Non-Detect
- Barium (Ba): 4,352 +/- 615 ppm
- Chromium (Cr): Negative/ Non-Detect
- Antimony (Sb): Negative/ Non-Detect
- Selenium (Se): Negative/ Non-Detect

While no one has done any studies as to the health impact of leaded glazes and paints on the exterior of 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”.
There are a LOT of terrific lead-free choices for casserole dishes out there. Check out THIS LINK to start.
