I don't suppose there is a way of surgically extracting it to leave you with simply a very well executed weight, not pretending to be something else......
So; does anybody know who the highly skilled lampworker was?
Well, the faker knows. By the way, did you sense the great maw of silence that greeted your question? This discussion has been on-going for years. Quality paperweights such as these fake Paul Ysart efforts don't get made in a vacuum. The maker had assistance. The problem is in actually naming the perpetrator. A false accusation might get you sued depending on how the revelation is written.
There's no doubt that everyone who is an expert on paperweights, especially paperweights from Scotland, has mentioned the name of the fake Ysart maker in private. There are only a handful of paperweight makers who could have made these weights. The name is certainly well-known to you and to all of us. The maker has talent and probably needed a quick bob during a fallow period in his life. Perhaps he needed money to maintain his studio. Did he commit a crime? Yes he did. Fraud is a crime.
The issue is discussed in the book Masterworks: The Paperweights Of Paul Ysart by Colin Mahoney. Ysart himself said that the fakes were not his work. It would be interesting to know who he suspected of being the culprit.
The person who made the paperweights is from Scotland and has been active in the glass paperweight field for decades. That's all we're ever allowed to say. But you can do the math as well as anyone else.
