Antique Pink Cased Satin Glass Victorian Boboche.  Circa late 19th century. About 4" diameter.  Tightly crimped and ruffled.  Ribbed Swirl pattern on the exterior.  Boboches were used to catch the wax drippings from candles.  No chips or cracks.  ORNATE. Delicate.  VERY Nice!  It would be wonderful to have a set of six or eight of these, but this is the only one we have.
