This rare vaseline glass relish server has no maker's mark but has been tested -- it glows bright green under a black light.  It measures 6" across.  This iridescent green vaseline glass is highly sought after as it is no longer produced due to the trace uranium property that makes it glow.  There is a crack at the base and a chip on the rim which I taped, and let you glue it.  It is not broken though and should go to a home that will appreciate this rare glass.  No Reserve.
