Certainly, the outline of the cut rim and van dyke would be correct. Old school term still much in use. Crenelated [ relating to battlements ] more descriptive to me [ I did have to look it up ]. The extra cuts within the shaped rim are a nice touch on the bowl in the link provided by THEWINGEDSPINX. Mine just has drape cuts that join together under every high point. The link was informative in the sense that I looked for wear under the rim to see if it was hung in the metal holder like the bowl in the link. Upon inspection there is no wear and also noticed that under the rim is panel cut to match the cuts below, wow.
[m] thanks for the link, always interested in documented pieces. What interested me most was the stoppers on the decanters. The hollow blown/cut stopper predominates in American cut glass of this period, although usually less refined. My new obsession is trying to delineate the difference between American and English cut glass in this period, roughly 1820- 1840. I noticed the bowls pictured in your link and one seems to have a more flare to the rim, different blowers on the blanks? After all the cutter can only cut the blank he has.
