"Uraline Candlestick, Late 19th Century"
Very pretty uraline glass candlestick, gadrooned foot and barrel and with a binet similar to a flower corolla. Uraline is a glass in which uranium has been incorporated, most of the time in the form of uranium oxide or diuranate. In the absence of any other dye, the color of uraline, which varies from yellow to green, depends on the level of oxidation of the material and its concentration of uranium ions. The characteristic of uraline objects is that they glow with a green fluorescent light when placed under ultraviolet light. Uraline became popular around the second half of the 19th century and enjoyed its golden age between 1880 and 1920.
