The use of uranium glass dates back to at least 79 AD,[REF] the date of a mosaic containing yellow glass with 1% uranium oxide found in a Roman villa on Cape Posillipo in the Bay of Naples, Italy by R. T. Gunther of the University of Oxford in 1912 [REF].
Martin Klaproth (1743-1817), who discovered uranium, later experimented with the use of the element as a glass colourant.
