I just wanted to share this fun piece with the group. The wine rinser was used in both the 18th and 19th centuries in the elegant Victorian homes to rinse the wine glass between courses, as a new wine was served with each course. In doing a google search, the Mount Vernon online store (home to George Washington), offers a reproduction and explains this information. There are other google references also to wine rinsers on the internet. That search (through several pages of listings) showed me amethyst, red, clear, cobalt, a dark green, and the closest one to mine, a uranium green version with etched grape leaves and grapes and cut panels near the bottom.
Measuring across the round (not the spout area), it is 5 1/8" (13cm) and 3 1/4" tall (8cm). There are nine cut flat panels around the outside and a 27-point star on the underside, which was cut in to hide the pontil mark. It is leaded crystal and vaseline. The stem is also leaded glass, but was purchased separately.
I have seen only one other made in vaseline glass, and it was a perfect match to this one.
