Borosilicate Glass 2-Piece Set Glass Ear Cuff Ear Cuff Glass Glass Craft

About 10 years ago, I got really into borosilicate glass and bought quite a bit. (I still find myself buying it when I see it...)
I'd find pieces at markets and festivals and immediately buy them, accumulating a large collection...

I'm listing them little by little.

These are made from borosilicate glass, melted using a high-temperature oxygen torch.
Borosilicate glass is known for its high transparency, heat resistance, and strength.

This is a set of two ear cuffs.
