uranium-glass necklace: UV-vis by wombat1138 uranium-glass necklace: UV-vis by wombat1138
Same necklace, same position/setting as in the incandescent-light pic; the lightbulb is still on, but I've also added illumination from my nifty lil' borderline UV/violet LED thingie. As would be expected, the green fluorescence is lower from the aqua parts of the bicolor beads; conversely, the crackle-glass beads appear somewhat brighter than the uniformly-textured ones because of reflections from the internal fissues.
