I didn't see the photo of the top of the piece! Golly, I feel quite silly now.

I thought Soledivo meant the pattern within the clear gather of glass around the body. Ooops! Yes, I feel inclined to agree with Adam now.
I had a bit of trouble looking at the photo's so maybe I thought I'd seen them all when I hadn't. :mus:
Going back to the functionality of art glass

a 'perfume bottle' doesn't have to be functional either. I don't think anyone actually uses them for perfume these days, do they? The oasis (for want of a better word) for the liquid perfume can be very small compared to the overall size of the bottle. Perhaps you could call some of them a kind of boast, or conceit of a glassmaker, showing their artistic skill with a nod towards past designs.
Of course, some people collect perfume bottles, so they'll always be popular and will continue to be made by skilled artisans, regardless of whether people use them for their proposed purpose.
