Vintage Glass Marble Lot 25 Count Swirl Mixed UV Cadmium Vaseline Slag #MB14

This curated 25-piece vintage machine-made glass marble collection showcases classic mid-century American glasshouse craftsmanship, featuring vibrant opaque milk glass and colored bases layered with intricate swirl, slag, and patch patterns. The grouping highlights an array of historic color formulations, including fiery red-orange ribbons on pure white matrixes, deep cobalt swirls, jade-and-seafoam green bands, smokey charcoal marbling, and sunny yellow accents. Specialized batch chemistry is on full display under longwave ultraviolet illumination, with select examples featuring heat-fused cadmium compounds that produce an intense fiery red-orange fluorescence alongside subtle uranium-reactive greenish glows, while non-reactive bases remain inert. Spanning traditional machine-rolled swirl techniques and sought-after color combinations, this collection represents the golden era of collectible American glass manufacturing. # MB14
