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.\u003c\/p\u003e","brand":"My Consignment Store","offers":[{"title":"Default Title","offer_id":53826404745579,"sku":"MB6","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/0669\/9371\/files\/IMG_5561.jpg?v=1788906612","url":"https:\/\/myconsignmentstore.com\/products\/vintage-west-virginia-swirl-uranium-glass-marbles-uv-glow-lot-25-ct","provider":"My Consignment Store","version":"1.0","type":"link"}
