You can make your own glass loops to hang a vessel from a cord. Either one loop like a pitcher, or 2 loops like handles.
I made this a very long time ago. If I was to hang it, I'd probably loop a cord through the one side without the jump ring so it would hang off center.
For vessels you'd want to stand upright that don't have a flat bottom, there are little acrylic disks made for displaying marbles. Perhaps they'd work on some of them but they aren't very deep. Or you could make some stands to be more part of the whole, with wire (or glass).
