This is no place for a debate over the relative merits of Anglo-Irish vs. American cut glass, but it seems to me Glass has a rather Anglocentric perspective of the industry and consequently her ideas about these vases. So, a few comments/questions...
Ah the American brilliant period 1880 to 1915, basically British Georgian Regency copy's with different pattern cutting. LOL.
Hardly! The glass was usually thicker and therefore could be more deeply cut, most of the dominant motifs were different and more ornate, and the patterns often combined many motifs on one piece, totally covering it. And although American cutting houses adapted some English and Irish Regency motifs during the period, according to Daniel's
Cut and Engraved Glass American output then far surpassed English and Irish production and little was imported, so you could just as easily say that ABP copied Early American Period designs (though that isn't really true, either).
Cut glass has been produced in England and Ireland and America since 1780. Cut glass had progressed at a fast rate with the best machinery and the most highly skilled glass cutters in the world based in the UK ...and some of those cutters emigrated to the US. I don't know about the machinery - how did it differ from that used in the US? By the 1820s rich cut crisp British crystal glass from this period is the best in the world with the rest of the world to follow. Some say the American lead glass of this time has greater clarity. There is plenty of simple cut glass during the late Georgian period but there is also lots of Georgian glass cut deep and with intrigate patterns. These vases are not typical Victorian or Edwardian style They certainly are! due to the quality of the cutting I don't understand your point about the quality at all. There was a lot of high-quality cutting done in the late 19th/early 20th C. and have a strong Georgian American influence. Don't you just love the British xx
By the way, fire polishing has been used on some glass for over 200 years. Has it been used to polish cuttings for that long? I thought most pre-1900 cut glass was hand-polished, but I would be very interested to know if that's not the case.
Once again, this is an American motif/pattern, Harvard, first used by Hawkes around 1900. There are a few American patterns that were adopted by English companies; Russian was a particularly popular one.
Georgian patterns are simple by comparison.
This is my quote. I should have said "Georgian motifs" are simple by comparison, since there are Georgian patterns that combined more motifs than these vases. In the case of Harvard, it's considered both a pattern that can be used alone, and a motif that can be used with other motifs to make up a pattern.
