Bowl (8) - Glass - 8 wire-glass finger bowls

Draadglas finger bowls for use at the dining table when you need to eat with your hands, e.g. large prawns whose tails must be removed. Then you can rinse your fingers briefly in the bowl. Sometimes there was a slice of lemon in it.
Beautiful antique green color with a gold rim on top. Unfortunately one of the eight has a tiny chip on the upper rim.
See last photo.
Draadglas is a century old and these bowls are as well. The bottom suggests, on the one hand, that it is mouth-blown (the worn-down pontoon) but other bowls do not have that. So..?
