Hi, I have a large amber vase similar in many ways to your green. On that basis alone, I doubt very much if yours is very, very old.
I note from your other post regarding [Andries] 'Copier or copied', that a 'guest' has replied in Dutch. I wonder if you would be so kind as to translate it for us?
I have asked my niece to do so but she may not reply for a while as she works for an international company and travels a lot.
I am also interested in your choice of 'Monikker' [ nick-name or 'identifier' ]
Glasshole sounds really interesting, what is the Dutch translation? What is the derivation? Sounds like you are a glassy 'black hole'!!!!!!!!!!
