Vintage West Virginia Swirl Marbles Mixed Partial UV Glow Lot 25 Ct

Originating from the historic Ohio River Valley glass corridor, this collection highlights mid-century machine-made swirl marbles produced by iconic West Virginia manufacturers such as Alley Agate Company, Ravenswood Novelty Works, and Cairo Novelty Company. Set against dense opaque milk-white glass bases, each example displays bold ribboning and sweeping brushstrokes in cobalt blue, forest green, rich chocolate brown, golden yellow, and deep red. A select portion of the grouping incorporates authentic mid-century chemical dopants, revealing striking fiery cadmium-selenium orange and red fluorescence under ultraviolet blacklight alongside non-reactive examples. Representing the golden era of Appalachian glass manufacturing, these authentic vintage swirls capture the historic techniques, vibrant color formulations, and mechanical roll processes defining mid-20th-century American marble heritage.
