Murano Hand-Blown Murrine Glass Tumbler

This is a hand-blown glass tumbler or vessel, likely of Murano origin, featuring a 'murrine' or 'canne' technique application. The item is constructed from translucent, clear glass with an ovoid, slightly bulbous body and a fire-polished rim. It displays a distinct vertical ribbed texture known as 'balloton' optic effect or mold-blown ribbing, which creates a rhythmic, wave-like surface. Suspended within the vertical ridges are decorative cobalt blue dots, resembling a stylized polka dot or 'Macchie' pattern. The application of the blue glass is precise, indicating a high level of craftsmanship consistent with mid-to-late 20th-century Italian glassmaking. The item appears to be in excellent condition with no visible cracks, large chips, or significant clouding, though light surface scratches on the base would be expected for an item of this age. The glass exhibits a clear, brilliant quality with minimal seed bubbles. While no specific maker's mark is visible in the photograph, the style and execution are strongly reminiscent of mid-century makers like Venini or Carlo Moretti. The design reflects a sophisticated, modern aesthetic that bridges the gap between functional tableware and decorative art glass.
