Uranium glass has a hallmark green color, that can sometimes have a blue tint as well. Uranium glass shold glow flouresant green under both 395nm and 365nm uv light.
Josef Reidel is credited with inventing uranium glass in 1830, as it was originally used as a means to achieve unique bright green and yellow colored glass. Commercial uranium glass production was prohibited in 1943 by the US government to prioritize nuclear weapons production during and after WWII. As of 1959 uranium glass production was again legal, however in very low volume due to high costs of uranium oxide and other trends coming into the glass market. This makes uranium glass not only historically interesting but also truly unique and limited, with some pieces being very rare and valuable.
Some express concern over the radioactive properties of the uranium glass, however it is generally considered no more dangerous than the radiation given off by TVs or microwaves. As a precaution, it is not recommended to use uranium glass to store food/liquid for an extended period, as the contents will accumilate the low does of radiation over time.
