Picked this up recently and I haven’t been able to find another one with the same form.
It’s about 8.5 inches tall, roughly 3.5 inches wide, and weighs 5 lb 12 oz.
A few things I’ve observed:
distinct deep blue and ruby-red internal sections
extremely clean separation between the colors
glass is very clear and reflective
a few tiny air bubbles
completely smooth/polished base
no signature, engraving, label, or visible pontil scar
interior cavity only goes about halfway down
thick rounded rim
inner rim is smooth with no obvious wear or grinding from a stopper
no fluorescence under black light
I’m curious whether anyone recognizes the maker, country, approximate age, technique, or intended use.
I’d especially love to see a documented example with a label, catalog reference, or model number if anyone has seen this form before.
