John - exciting! So, 50s, 60s maybe. Attributable to one of those Toso guys - is that okay to say? When I searched the recommended glass search, I found Dino Martens name mentioned with Toso, but that is not what I have, correct? These are rather heavy and thick.
Lustrousstone- Happy to learn the proper names! But also, if I list these, without using the commonly used “latticino”, I’m afraid half the interested buyers will click on by. I will correct this in a description though.
Thank you both for sharing your knowledge!
