Vintage West Virginia Swirl Uranium Glass Marbles UV Glow Lot 25 Ct

Originating from the mid-century manufacturing tradition of the West Virginia glass corridor, this collection highlights authentic vintage machine-made swirl marbles produced by historic regional glassmakers such as Ravenswood Novelty Works and Alley Agate Company. Formed from dense opaque milk glass, semi-translucent wisps, and transparent tinted base glass, these examples display classic looping ribbons, interior feathering, and graceful surface swirls in rich sky blues, deep aquas, and emerald green tones. A defining feature of this grouping is the extensive presence of authentic vintage uranium dioxide batch doping; when exposed to ultraviolet blacklight, the marbles emit intense, vivid fluorescent green glows across nearly the entire selection. Displaying traditional Appalachian shear marks, machine rolls, and mid-20th-century glass batch craftsmanship, this collection is an exceptional assembly for both vintage American marble collectors and ultraviolet glass enthusiasts.
