Turquoise Murano Cup with Silver Inclusion UV Reactive Barovier & Toso

Superb small sculptural bowl made of massive Murano art glass (1950s-1960s) from the prestigious Barovier & Toso manufacture. This rare piece illustrates the virtuosity of Venetian workshops, combining a turquoise blue hue with rich silver inclusions (foglia d'argento). The material features a spectacular frosted or cracked internal effect, achieved through thermal shock and the bursting of metal leaves during blowing. The whole is encapsulated in a thick layer of crystal (sommerso), giving an astonishing depth to the decor. The exceptional feature of this model lies in its glass composition: the addition of manganese in the glass paste gives it a spectacular intense green fluorescence under UV light (black light), a highly sought-after characteristic among collectors. The organic silhouette has been shaped hot and freehand (a mano libera). The base features a ground and polished pontil (molato). The condition is excellent, with no cracks or chips. Slight micro-scratches from use under the base attest to its age. Dimensions: Height 6 cm|Width 13 cm|Weight 612 g. 📦 SHIPPING: Ultra-secure custom packaging. Tracked shipping.
