Green Akro Agate Slag Glass Daffodil Vase

Slag glass is opaque, marbled glassware made from pressed glass, typically featuring colored streaks or swirls, most commonly white or cream, against a background of another color like brown, purple, blue, or green.

It gets its name from «slag», a glass-like residue left over from the smelting of metal ores, and was first produced in the late 1800s, often used for lampshades and decorative objects. Each piece is considered unique due to the unpredictable nature of the streaking.
