Uranium
One would think that Uranium wasn’t available as a household product, but Fiestaware, a collectable kitchenware rtange from Bauer Pottery Company used Uranium trioxide between 1936 and 1943 and 1959-1969, only stopping so that the US could utilize every scrap in the research and building of the only atomic bomb to be used in war.
It also comes in the form of knick-knacks and trinkets in what is known as ‘vaseline glass’. Uranium compounds have been used for centuries to color glass. A 2,000 year old sample of yellow glass found near Naples, Italy contains uranium oxide.
