Roys wife posting here <waves>, hope this doesn't appear rude, but why would you exclude vases and perfume bottles from an exhibition of glass? domestic means the home and people do still have vases in their homes and show me one female who doesnt have a perfume bottle for display even if empty, even my daughter who has zero interest in glass hankers after a nice iridescent atomiser from times past.
You cant exclude items on the basis they are no longer used otherwise you may as well exclude other clutter people very rarely use nowadays such as decanting anything into pots such as mint, mustard, marmalade, butter dishes, match strikers, etc, so many people do not bother.
If I was visiting a museum with my other half or the family, I would not go somewhere just to view tableware/functional/industrial design, that is a man thing only imo and far too lofty. Being of a creative & artistic bent myself I would want to view the decorative too, cant there be a mixture of the two?
Not my museum of course, just my opinion.
