Hi there, this is Roy's wife (Carol) , Roy has kindly given me permission to join in the conversation with my own thoughts on this piece and Late Regency/Early Victorian cut glass in general from England/Ireland -v- continental imports/output.
The only book we currently have on antique Irish glass is Old Irish Glass by Mrs. Graydon Stannus so we do need to get some more books on the subject as we are reduced to googling for further information. Having said that, Mrs Stannus was an expert in her field who had a breadth of knowledge on the subject, despite her underhand practices of selling known fakes and adding further cutting to "improve" pieces, which has since come to light. It would be fair to say the whole tone of her book is how to identify Old Irish Glass, written possibly by one who has superior knowledge and thought the average reader had a cats chance in hell of finding anything authentic themselves. She gives very detailed information on how to identify Victorian pieces passed off as earlier regency pieces i.e. copies and also how to distinguish bohemian imports too. There is then also the issue of design. As already mentioned design was similar across many countries relating to various eras and various mediums. Most people trained up in antiques can tell at a glance if something is mid Victorian or regency after a while at a glance from the overall look of a piece. So, regardless of whether something originated from Ireland, England or Europe it has a look about it that says 1790 at the latest, 1800 - 1830, then 1840 - 1860. It can take years to assimilate from experience, but would be fair to say that generally speaking earlier glass, particularly Georgian from 1790 is a lot plainer in finish and cut than something produced around 1850, which by that time is almost more heavily cut and much thicker, chunkier glass. This is my opinion thus far (although Im an amateur collector).
With this in mind and before I pass onto Mrs.Stannus's identification comments, I myself believe my piece to have been decorated & produced around 1840 - 1860. I don't necessarily believe it to be purely Irish in origin, but to come under the umbrella term of Anglo Irish Glass rather than continental.
Certainly earlier Irish glass from the pictures Ive seen so far are much plainer in design with either plain or star cut feet. The only examples of rollover/turnover rims being bowls, with most of the heavy cutting being on the rim. Most of the sweetmeat dishes are covered, although a lot of them have extensive cutting over the whole body of the piece. That is not to exclude however turnover Urns. Im of the opinion my piece is an Urn/Vase and did not have a lid, there is no inner ridge and the turnover would not necessitate a lid being warranted. I provide a link here to a pair of Urns similar in every way to my own piece.

But back to Mrs.Stannus and a brief summary of her characteristics of irish Glass & identification of such, plus her description of fake pieces:-
Weight :- Generally very heavy, with the exception of course of the earlier blown pieces.
They can be distinguished from foreign imports of similar weight by the presence of minute air bubbles in the Irish pieces, whereas the foreign pieces had minute specks of sand in what she calls the "metal". She attributes this to the faulty stirring of the molten metal in Irish glass and they can be so small as to need identification with a magnifying glass if necessary.
Colour:- Irish glass has a steel grey tone. Atrributed to all the glasshouses in Ireland obtaining their materials for glassmaking from the same source. With some slight variations as follows: Cork glass sometimes had a yellowish tinge. Waterford glass having a cloudy "bloom" covering the metal which when rubbed off reappears. When it is not possible to identify the exact area to which the Irish glass originated from it was referred to in general as Munster glass, which failed to include the pieces produced in the Dublin glasshouses, which in turn also got confused for Waterford and Cork glass!.
Resilience:- So much stronger & tougher than ordinary glass and to the point it takes a quite severe blow to chip or even break it.
Warmth:- Irish glass did not feel as hard and cold as English or European glass of the same period. Very similar to the differences of between say earthenware and china to the touch.
The Ring:- Wheras English glass/crystal of the same period had a definitive ring to it, irish glass is describes as having a deeper throb/vibrato. European glass of the same period has a flatter sound or even no ring at all.
Then the question of fakes is described thus:-
Irish glass has been much copied at all periods of its production but has successfully withstood the fakers best abilities if one learns to distinguish the differences. So that although it has been made of sufficient excellence to deceive the inexperienced and unwary it cannot be be copied sufficiently well to deceive the connoisseur.
The finest reproductions from France, Belgium, Holland, Germany & Bohemia all fail in colour & texture, though credit is given to the excellent cutting of these pieces.
The first clue was in the colour of the fakes. The colour noticeably falls in the pieces, easier to spot in the taller items, leaving the tops whiter than the bases. In particular she mentions the pieces arriving from Europe, most especially from Bohemia arriving to England which are not only lighter in weight but all had a peculiar pink tinge. which become a deeper pink the larger the object became.
A lot of the fakes from all eras failed to acquire the correct weight (with the exception of the earlier Georgian blown pieces).
The earlier Georgian blown pieces from around 1735 to 1750 which were very light were quite plain and hardly cut, being mostly engraved. Whereas the faked pieces tended to forget this point and be cut all over. With the later pieces from 1790 to around 1890 when the glasshouses closed in Ireland (not including the middle period when production slumped due to the glass tax) authentic pieces got heavier and more elaborately cut, with the same uniform grey steel colour. The irish glass continued all through this period to have the minute air bubbles especially visible in the pedestal/footed clear areas, for some reason the bubbles didn't rise and were most visible in the bases of the pieces, whereas the foreign imports continued to have the specks of sand which she concludes must be a peculiarity of foreign glass & the chemical composition of the salts they used which differed to the formula used in Ireland.
Colour:- The glass of Waterford, Cork & Dublin defied the copyist more than any other. Whether this was down to the Irish formula or the atmospheric conditions in Ireland at that time she was unsure, but the copies from abroad had also noticed the differences sufficiently enough as to add thin cobalt or aquamarine in attempt to duplicate the colour, which had a tendency to settle so that the colour fell in the article slightly enough to be visible to the naked, trained eye. The irish formula for glass was lead oxide, potash soda and silica and nothing else. There should be no trace of a blue, pink or even a green tinge to the glass.
A lot of the original Irish glass was exported to America, the West Indies, Spain, Portugal , France & Belgium and extensively copied but all failed on either the colour and texture. nearly 100% off the European/Bohemian pieces either suffered from colour drop/white tops (Europe), pink tinges (Bohemia) the addition of visible Cobalt Blue (mainland Europe in general).
Hope this is of interest to people in general, I cant vouch for the accuracy of Mrs.Graydon Stannus book but it is written in depth with many examples of pictures and extensive examples of the patterns used for cutting and Roy stumbled across the book at a second hand book shop and bought it even though neither of us have any experience of Old Irish Glass but we tend to read up on different thing s and it all adds to our knowledge when collecting or buying things.
I have to say I believe my piece passes all the test Mrs.Stannus describes and I spotted it at Kempton when I went with Roy a few months ago. I normally collect antique jewellery. Ive found over the years that accompanying Roy to antique fairs he would vanish as soon as the gates opened and I would be left to amuse myself for a few hours, so I decided to collect antique jewellery. However ive always had a fondness for cut glass and we have some wonderful pieces of American brilliant, but basically my dinnerware/drinking glasses all tend to be vintage Waterford, Royal Brierly etc... just 20thc stuff but lovely things anyway to use. However I do love neo classical/Georgian things I just cant afford it!
But when I walked past this particular stall at Kempton that Urn spoke to me and said "Look at me, Im beautiful" I couldn't walk past, but I didn't have the £90 they wanted , then it wasn't there for a few months as the stall holders were ill & then xmas came and finally Roy asked them did they still have it and they brought it along and called him over the next time they spotted him , which was very kind of them and bless them they didn't up the price, he knocked them down to £75 which I think is a good price for what it is as I have no intention of selling it & have no real idea of what it would sell for if I got bored of it. Knowing my luck on Ebay Id be lucky to get 50 quid.
Anyway Roy brings home so much glass and I get lengthy lectures on price/value/maker etc that Ive learnt all about glass accidentally
