Uranium Glass Two-Piece Candle HolderI dont think this was originally sold this way, but I thought it made a beautiful set. The base does not fluoresce. It is, however, 1940s 1950s Fenton silver crest and is in beautiful condition. The star of this set is the top! While I am not sure, I believe this is cased Fenton yellow opalescent glass. Wow goes this glow! It is designed to be placed into a candlestick holder. Then you can either leave it empty or put a candle or flowers in the top.
