Brooch, Glass, Vintage Brooch, Abstract Pattern This vintage art glass brooch features an impressive abstract design with a deep red base, shimmering gold-like accents, and blended blues and greens. It's made using a technique where colored glass is melted at high temperatures and layered to create the form. The resulting layers of color within the glass offer various expressions depending on the light. Unlike cloisonné, which involves firing enamel onto a metal base, this piece utilizes the texture and thickness of the glass itself. A simple brooch clasp is attached to the back, evoking a retro-modern design from around the 1960s to 1980s. Its organic and painterly atmosphere is a charm not found in mass-produced items. This vintage item is recommended not only as an accent to your outfit but also as a collectible or art piece.
