AI Appraisal Estimate

This is a hand-formed art glass vase characterized by its deep, vibrant cobalt blue color and striking asymmetrical silhouette. The vessel stands as a tall, slender form with an organic, free-flowing geometry. It features a weighted squared base for stability, which tapers slightly before expanding into a wider, undulating body with pinched or pulled sides. The neck is narrow and ends in a polished, slightly flat rim. Based on the thick glass walls and the clarity of the translucence, this piece appears to be leaded glass or high-quality soda-lime glass. The construction suggests it was mold-blown and then hand-finished, typical of Mid-Century Modern Scandinavian or Italian (Murano-style) glassmaking from the 1960s to 1970s. The surface shows a high-gloss finish with no visible chips, cracks, or large internal air bubbles, which indicates a high level of craftsmanship. While no maker's mark is visible in the photograph, the style resembles that of makers such as Blenko or various Scandinavian art houses. There is a slight patina of dust, but the structural condition appears excellent with minimal surface abrasions or base wear.

Based on my visual examination of this mid-century modern cobalt blue art glass vase, I find it to be a well-executed example of mid-20th-century decorative glassware. The deep cobalt saturation and weighted base are characteristic of high-quality soda-lime glass production common between 1960 and 1975. The asymmetrical, organic form suggests a design influence from either the American maker Blenko (specifically designs by Joel Philip Myers) or Scandinavian firms such as Holmegaard or Aseda. The condition appears Excellent; the glass clarity is high with no evidence of 'sick glass' or significant internal calcification. The absence of a visible pontil mark suggests a mold-blown process with a polished finish, which is a hallmark of professional-grade studio production. The current market for mid-century cobalt glass remains stable, though value is currently driven more by aesthetic appeal than by rarity unless a specific designer can be verified. Comparables for unmasked pieces of this scale and color typically realize between $100 and $250 at specialized antique auctions. I must note the following limitations: this appraisal is based solely on digital imagery. A physical inspection is required to check for micro-flea bites along the rim, base wear consistent with age, and the presence of any acid-etched signatures that are not visible in the photographs. To definitively attribute this to a specific maker like Blenko or a Swedish studio, provenance documentation or a catalog match of this exact height and weight would be necessary. Without a signature or label, the value reflects its status as a high-quality 'in the style of' decorative object.
