Vintage Glass Marble Lot 25 Count Swirl UV Cadmium Uranium Slag #MB18

A curated 25-piece vintage machine-made glass marble collection highlighting classic American glasshouse manufacturing runs from the historic boom era. The assortment features dense, opaque white milk glass matrixes layered with intricate surface swirls, patches, and slag ribbons spanning vibrant cobalt blues, emerald greens, cherry reds, and sunshine yellows. Reflecting specialized historical batch formulas, select examples exhibit strong longwave ultraviolet reactivity, with heat-fused cadmium colorants producing vivid orange-red fluorescence alongside targeted uranium-doped glass exhibiting bright neon-green luminescence, while non-reactive bases remain inert. Spanning traditional machine-rolled craftsmanship, sought-after patch patterns, and authentic mid-century mineral chemistry, this 25-count lot offers outstanding appeal for specialty marble collectors and antique glass enthusiasts. # MB18
