1960s Mid-century Flavio Poli for Seguso Murano Sommerso glass ashtray or catch-all

1960s mid-century modern Italian art glass vessel designed by master artisan Flavio Poli for Seguso Vetri d'Arte (Murano, Italy). Functioning seamlessly as a table ashtray, catch-all (vide poche), or standalone desk sculpture, this piece represents peak 20th-century Venetian glasscraft. Executed in the iconic Sommerso (submerged) technique, a painstaking process of layering molten coloured glass to create vivid optical depth without colour bleed. A rich, jewel-toned deep magenta/cranberry red interior bowl is suspended inside a subtle yellow-amber transition halo, encased within a substantial layer of heavy clear glass. Features a heavy geometric square-block/cube outer form with smooth, clean-cut facets that act as a prism, contrasting against a soft, rounded U-shaped interior basin. It's in excellent condition, free of any chips, cracks, or scratches.
