Thank you for your response. Do you perhaps have a picture of the vase you talk about in the book? Or aren't you allowed to publish that here?
About the rim:
What do you mean with it being "cut"? As in hand/wheel cut instead of molded?
I'm not home right now but Im sure its polished. It doesn''t really have rough edges or anything.
I'm sorry it might seems that I know quite a lot about glass itself, but I really don't.
The picture of the link you placed, which is attributed to Richardson..
I'm pretty sure you're right about it being a Harrach piece.
I came across a vase earlier this week. And I kind of ran out of budget, otherwise I perhaps would have bought it myself. This is an example which I would not attribute to Harrach. Could be Richardson or Russian. But the quality isn't really impressing.
