Vintage Glass Marble Lot 25 Count Swirl UV Cadmium Vaseline Slag Runs #MB17

This 25-piece vintage machine-made glass marble collection highlights classic American glasshouse manufacturing runs from the historic boom era, showcasing dense opaque and translucent matrixes finished with intricate swirl ribbons, slag veining, and patch configurations. The assortment spans vibrant opaque sunshine yellows, milk glass bases layered with contrasting chocolate and yellow swirls, light sky blues, rich persimmon-orange slags, and deep black-base spheres accented with yellow ribbons. Highlighting specialized historical glassmaker formulations, select pieces exhibit intense ultraviolet longwave reactivity, including fiery orange and golden cadmium-reactive ribbons alongside soft greenish uranium-bearing glows, while the surrounding dark bases and white matrices remain inert. Reflecting traditional machine-rolled craftsmanship, sought-after patch patterns, and authentic mid-century batch chemistry, this curated grouping provides standout appeal for antique glass and vintage marble collectors. # MB17
