AI Appraisal Estimate

This is a hand-blown art glass vase characterized by a deep, translucent cobalt blue hue. The vessel features a classic baluster-shaped body that tapers significantly toward a narrow, rounded base, topped with a wide, flared, and heavily rolled rim. The thickness of the glass at the rim suggests a mid-20th-century craftsmanship style typical of Scandinavian or American art glass houses. The surface is highly reflective with a glossy finish, though close inspection reveals a significant chip or impact mark on the upper right edge of the rim, exposing the interior glass structure and potentially indicating a point of weakness. There is no visible maker's mark or signature in the provided view, but the form is consistent with mid-century modern aesthetic trends. Light surface abrasions and dust are present, particularly around the base, which is expected for a vintage decorative piece. The craftsmanship is high, indicated by the uniformity of color and the controlled transition between the neck and the wide flared mouth.

My examination of this cobalt blue artillery-style vase reveals a high-quality example of mid-20th-century artisan glasswork, likely of Scandinavian origin or perhaps from an American firm like Blenko. The deep, uniform color and the precision of the heavily rolled rim indicate a high level of technical proficiency. However, value is significantly impacted by the visible chip on the upper rim. In the art glass market, structural damage of this nature typically reduces the secondary market value by 40-60%, as collectors prioritize pristine condition. While the 'artillery' form remains popular among Mid-Century Modern enthusiasts, the lack of a visible signature further limits its valuation to the 'attributed' category. Comparable sales for similar unsigned cobalt vases in perfect condition range from $250 to $350; the current valuation reflects the necessary discount for the rim damage. It is important to note that this appraisal is based on photographic evidence alone. To definitively confirm the origin and authenticity, I would require an in-person inspection of the pontil mark on the base to identify the tool type used, as well as ultraviolet light testing to examine the glass composition. The absence of a maker's mark means provenance documentation or original catalog references would be necessary to elevate this piece from a decorative object to a documented museum-grade collectible.
