Fiestaware - Radioactive!
"First made in 1936, Fiestaware was instantly popular with its bright colors and modern design. Radioactive thorium was used to produce the signature orange, red, and green glazes. Fiesta was discontinued in 1973 and reintroduced in 1986, using lead-free and non-radioactive glazes."
I remember in college physics lab, using pieces of orange fiestaware as radiactive sources for experiments in radiation decay! There are probably still people eating off of radioactive fiestaware dishes today!
These dishes were on display at the National Museum of Nuclear Science and History in Albuquerque, NM. The quote comes from their display.
