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\u003c\/p\u003e","brand":"My Consignment Store","offers":[{"title":"Default Title","offer_id":53827787522411,"sku":"MB11","price":40.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/0669\/9371\/files\/IMG_5573.jpg?v=1788949884","url":"https:\/\/myconsignmentstore.com\/products\/vintage-clear-base-glass-marble-lot-25ct-surface-swirl-patch-mixed-uv-cadmium-mb11","provider":"My Consignment Store","version":"1.0","type":"link"}
