AI Appraisal Estimate

This is a small, teal blue decorative art glass bowl featuring a conical, tapered shape with a slightly irregular, wave-like rim. The primary physical characteristic is the exterior horizontal ribbing or 'undulated' texture that mimics water ripples, wrapping around the entire circumference of the vessel. Crafted from translucent glass with a vibrant turquoise-blue hue, the bowl demonstrates mid-century modern aesthetic influences. The construction appears to be mold-blown or pressed with a hand-finished rim. The piece sits on a small, narrow base. Condition-wise, the bowl appears to be in good vintage condition with no visible cracks or heavy chips in the photograph, though fine surface scratches or a pontil mark on the base might be present upon physical inspection. The texture provides a high degree of light refraction, enhancing the intensity of the blue color. While no specific maker's mark is visible in the image, this style is consistent with 20th-century decorative glassware from manufacturers like Blenko, Iittala, or various Murano-inspired workshops from the 1960s or 1970s. The organic feel and tactile surface quality are key indicators of its artisan-style manufacturing.

I have virtually examined this teal blue textured art glass bowl, which exhibits a conical form with distinctive horizontal undulations and a hand-finished, slightly irregular rim. The vibrant turquoise hue and mid-century modern profile suggest production during the 1960s or 1970s. The piece demonstrates quality craftsmanship consistent with Scandinavian or high-end American glass manufacturers of the era. I note the high light refraction caused by the exterior ribbing, which adds significant decorative appeal. Based on visual analysis, the condition appears excellent with no visible chips or fractures, though the value assumes minimal shelf wear on the base. The market for mid-century decorative glass remains stable; however, the lack of a visible maker's mark (such as Blenko or Iittala) places this in the 'attributed to' category, which slightly tempers the valuation. Similar unsigned textured bowls typically sell within the $65 to $110 range at specialty vintage boutiques. Limitations: This appraisal is based solely on digital imagery. For definitive authentication and a potentially higher valuation, an in-person inspection is required to check for a ground pontil mark, acid-etched signatures, or specific glass weight characteristics. Scientific analysis of the mineral content of the glass could further pinpoint the geographic origin (e.g., Murano vs. West Virginia), and original sales receipts or manufacturer labels would provide the provenance necessary to reach the upper tier of the market.
