Vintage Clear Base Glass Marble Lot 25ct Surface Swirl Patch Mixed UV Cadmium #MB11

A classic 25-piece grouping of vintage machine-made glass marbles featuring clear transparent matrixes decorated with distinct surface swirls, color patches, and ribbon-style veneer patterns. The selection highlights traditional mid-century glasshouse color runs, incorporating bold applications of bright yellow, cobalt blue, rich red, and milk-white opaque glass layered onto crystal-clear base spheres. Formulated using specialized historical mineral colorants, select pieces within the run contain heat-fused cadmium compounds that exhibit bright orange and golden fluorescence under longwave ultraviolet illumination while the clear base remains inert. This curated lot exemplifies the historic machine-rolled craftsmanship, distinctive surface-applied color designs, and vintage batch chemistry sought after by specialty marble and antique glass collectors. # MB11
