Hi, I am totally new to this board and I hope you can help me.

I have two very nice glasses and I am not able to find out where they are from. I guess it could be Murano:
First one are 6 champagne cups, 11 cm high, 9 cm in diameter. The foot is hollow and in clear glass with bubbles and approx 3mm thick. The bowl is in blue.
Second one are 8 Cognac glasses in green (foam?) glass. They are 11 cm high and 7,5 cm in diameter. The glass is pretty heavy and thick.
I really hope, somebody can tell me what it is.
Thank you in advance and best greetings from Hamburg
