I Found This at My Grandmother’s House: Made Entirely of Glass With Narrowed Openings All Around the Perimeter — What Is It?

While exploring my grandmother’s attic, I stumbled upon a curious object that immediately caught my eye. Made entirely of glass, it was delicate yet sturdy, with narrow openings all around its perimeter. Its design was unlike anything I’d seen before, and it made me wonder: what could it possibly be used for?

At first, I considered a few guesses — a decorative piece, a candle holder, maybe even some old kitchenware. But the more I examined it, the more fascinating it became.
