Hi Paul, I have collected many decanters over the years, but this particular decanter, that's if it is a decanter like you have mentioned, has left me totally bewildered.

Looking at the decanter again and having a second opinion, the shoulders are different. One slightly higher than the other. The facet cuts are different in shape and height of points are irregular around the circumference of the top area of the bowl. This along with info. within my initial description, would IMHO suggest that it is hand made. I have only washed the glass prior to taking pictures, using my assistant 'fairy' and a sponge

. Having left the decanter to dry, I have noticed that around the internal of the bowl, is definitely cloudy and dense in some areas. A few seeds are definitely visible, well that's what they look like and this is in the neck and bowl area. They do not protrude on the outer or inner area, but one shows a minute indentation in the glass around the seed.
Still researching this decanter, I did come across some genova design decanters where some had a very similar style and shape, which would suggest as you have mentioned, continental. I will try and see if I can find them again. The style of cuts with the points are definitely similar. The only difference was the amount of facet cuts around the actual decanter varied. There are 12 on mine.

As for shape, I don't think it's a shaft and globe (not quite enough prominence of shoulder) - could be a Prussian, which was very common in the C19. [/quote]
I currently unable to find any examples that might persuade me, that it maybe East German, but will bare this in mind.
Sometimes we take things for granted and must say, I am very grateful for the detailed info. you have provided regarding the positioning of the grinding tool in order to get the cuts and how it would not be possible to do it any other way. I now have a better understanding, as it does clearly makes sense.
Having compared this decanter to other glass, I would definitely say 19C. That was my initial thoughts, but did not want to be presumptious.
Not that I think it helps you much, but the only reference I've been able to find to UMJC is a religious one: the Union of Messianic Jewish Congregations http://www.umjc.org/
I'm idly wondering if the letters that look like JC could in fact be Of and if this might be an Orrefors piece... it reminds me of this one: http://images.replacements.com/images/images5/china/C/orrefors_orrefors_figurines_giftware_no_box_P0000014962S0052T2.jpg
Hi Anne, the inscribed lettering is UMCJ not UMJC and looking at the suggested sites you have kindly provided, has not convinced me in the slightest. I just can't see any comparison and hope Paul or anyone else can help support me on this. I just feel this in not the path I should be persuing, sorry! I am very grateful for your help though.

Oh! before I forget. Note: Within the pontil area, just above and to the right of the inscribed lettering already mentioned, there is, under magnification, what looks like the letter n p. The second stroke of the n at the lowest point joins the stroke on the lowest point of the letter p. The P looks rather larger than the n. I hope I have explained that o.k.

. I've just looked at the pictures posted and it does show it. I hope this will help.
