I had tried to update a message from 2006 and add new photos as there was some good info on it but it ate the whole thread saying I had already answered or something. So I will try again to put some photos.
---------still trying to figure out these from 2006. I am patient.
Here are photos of them since links are no longer good but info here is so.
Maybe some more info has been learned. They really are very different and unique. thanks. Sandy
Some sort of Scandinavian glass if I remember.
