Bingo! Hans, your suggestion proved successful, I made the hot needle test and the green beads are definitely plastic. The similarity with glass was such that I didn't even suspect they were plastic. Thank you Hans, and thank you Floor too: now I understand because, notwithstanding yhe presence of small bubbles, they didn't show traces of orientation due to winding or drawing.
