This is a lovely heavy glass in grey metal, with seven beautifully accurate long flake cuts. The dimensions (see gallery) are quite close to exact inch and fraction of an inch sizes, certainly much more so than a random or metric set of measurements, indicating that it was probably made in Britain or somewhere else using imperial measures. I can't find anything like it in my books.
The choice of seven for the number of flake cuts is interesting. An odd number yields quite different optical effects to an even number. Also an even number requires considerably more precision, as opposing cuts have to be exactly parallel in plan, otherwise it looks wrong. Also the choice of five, seven, or nine and more yields different optical characteristics.
The surprise is what you see when you look into the glass. Isn't that beautiful!
I would be grateful for any information on the date, origin, purpose, and name of this glass.
Thanks for looking,
Bernard C.
