Anne, I didn't take a picture because I was too busy pretending to be all insulted with his 'stupidity'... but when I took the pieces into the kitchen to re-wash them, I did secretly try one... it actually fit very well into the ear.
Dear me...
Rose, thank you for your photos, however, it's not quite what I meant... I do know that games of chess (and others) can be found in glass, even today.
My 'pawns' have got age to them... they're also wonky which leads me to believe they were just usable playing pieces for regular folk and children, hence my question about when glass was commonly used for games. OK, so it's a dumb question. :spls:
