This vintage Corningware Spice-o-Life casserole dish tested positive for lead when tested with an XRF instrument at 21,800 ppm Lead in the decoration on the outside of the dish.
On the plain white inside it was negative for Lead, Mercury, Cadmium and Arsenic. Tested in 2014.
In 2018 the amount of lead that is considered toxic in a modern/newly manufactured item intended for children is 90 ppm lead (or higher) in the coating or 100 ppm (or higher) in the substrate. Dishware is not considered to be an “item intended for children” (even newly made casseroles that are manufactured in the United States) and, as such, is not regulated for total lead content as tested/detectable with an XRF instrument.
