I was looking through different glass sites, actually looking for Paul S's lovely bowl, when I came accross this site.
Forgive me if it is 'old hat' to many of you, but it has so much on it, with hundeds of 'click on' links for lovely glass pieces.
I thought I should share it with you as they do appear IMHO to be very knowledgeable.
