That's an exhibition of ancient Greek glass vessels and items found from 14th to 4th century BC tombs in Macedonia and Thrace.The exhibition is at the Thessaloniki Archaeological Museum.
Some are really exceptional.Some are really well preserved. I have been at this exhibition twice.Once last year and once now with Frieda.
Here are the photos I took,flash was not allowed so I did my best.
First a golden wreath which used to have small glass beads on it.
