Title: Bizarre Giant Alexandrite Art Nouveau Modern Optic Vase
Post by: horochar on May 08, 2012, 02:41:22 AM

This is the strangest piece of art glass I've ever owned.  It is a HUGE optic glass vase in an art nouveau, carnival glass form, but with a strange modern "icicle" rim that look straight out of Iittala 1960s Tapio Wirkala or Timo Sarpaneva.  In interior lighting situations the color is ice blue, but in natural sunlight the color is a vibrant purple (!), which makes me think that it is alexandrite glass.  Any help would be appreciated.

Thanks,
Charles.

Your interior lighting will be fluorescent - it is fluorescing as pale blue!  Put the vase next to an old fashioned bulb and it will still be purple.  The proper name is Neodymium glass after the element that causes the colour change.   Sorry I can't help with the maker.
