AI Appraisal Estimate

This is a hand-blown decorative glass vase featuring a vibrant emerald green body set upon a contrasting clear glass pedestal base. The body of the vessel displays a distinct bulbed silhouette with a wide, flared rim and molded vertical ribbing that provides both texture and structural rhythm. A defining characteristic is the 'bullicante' or seeded glass technique, which has intentionally introduced thousands of uniform small air bubbles throughout the green glass to create a sparkling, effervescent effect. The construction appears to be a two-piece hand-blown assembly where the green vessel is heat-joined to the solid clear foot. The glass possesses a heavy, substantial quality indicative of mid-20th-century craftsmanship, likely originating from the 1960s or 1970s. While no maker's marks are visible in the photograph, the style and execution are consistent with art glass produced in regions like Empoli, Italy, or by American manufacturers such as Blenko. The piece appears to be in excellent condition with no visible chips, cracks, or significant surface scratches, maintaining a high gloss finish and clear transparency in the foot.

Based on my visual examination of this Mid-Century emerald green 'bullicante' glass vase, I have assessed its value within the current secondary market for vintage art glass. The piece exhibits high-quality craftsmanship characteristic of the 1960s Empoli region of Italy. The 'bullicante' technique is executed with remarkable uniformity, and the integration of the clear pedestal foot shows a clean heat-join typical of skilled hand-blown production. The vertical ribbing adds a structural sophistication that distinguishes this from more common mass-produced floral glass of the era. Condition appears excellent, with the glass retaining its high-gloss luster and no evidence of 'sick glass' or internal mineral staining. Market demand for vibrant, oversized Mid-Century Modern (MCM) decor remains steady, though the lack of a pontil mark or signature limits its ceiling compared to documented Blenko or Venini works. Comparables for unsigned Italian import glass of this scale and color typically realize between $115 and $180 at specialized vintage boutiques and online curated platforms. Note that this appraisal is based solely on digital imagery. For a definitive authentication, I would require a physical inspection to verify the presence of a ground pontil or specific shear marks on the rim, as well as a weight-to-volume ratio check to confirm the density of the lead content. Provenance documented through original foil labels (such as 'Stelvia' or 'Rossini') would likely increase the valuation by 20-30%. Without physical handling, I cannot definitively rule out modern high-fidelity reproductions, though the specific 'seed' pattern suggests authentic mid-century manufacture.
