AI Appraisal Estimate

This item is a large, decorative centerpiece bowl crafted from translucent cerulean blue glass. The bowl features a prominent organic, 'free-form' ruffled or scalloped rim that mimics a biomorphic flower or wavy movement. Its construction appears to be hand-blown or slumped, given the smooth, fire-polished edges and the fluid nature of the undulating folds. The material is a uniform pale blue with high transparency, allowing for light to pass through and create highlights on the interior curves. In terms of condition, the piece shows visible surface accumulation and particulates (dirt and debris) on the interior well, suggesting it has been stored without protection. While no major cracks are immediately apparent, there is a small marking or potential chip on the far right edge of the rim. The style is highly reminiscent of Mid-Century Modern glasswork, potentially from manufacturers like Blenko, Viking, or Empoli, likely dating from the 1960s to 1970s. The quality is indicated by the consistency of the glass color and the graceful execution of the undulating perimeter, making it a classic example of decorative 20th-century art glass.

I have examined the digital images of this Mid-Century Modern cobalt-cerulean blue glass centerpiece bowl. The piece exhibits characteristic traits of 1960s American stretch glass, specifically the 'swung' glass technique adopted by manufacturers like Viking or Smith. The biomorphic, ruffled rim is well-executed, though the presence of surface grime and a potential chip on the far right perimeter suggests the piece has not been curated in a protected environment, which negatively affects the valuation. Authenticity appears consistent with mid-market 20th-century decorative glass, though I cannot confirm the presence of a pontil mark or maker's acid-etched signature from these views. The market for non-signed MCM glass remains stable but saturated with similar production-line items from the era, limiting rarity. Comparable sales for 12-15 inch blue handkerchief or ruffled bowls typically fall in the $40-$80 range. The primary value drivers here are the vibrant color and the 'retro' aesthetic appeal rather than brand exclusivity. Limitations: This evaluation is based on visual data alone. A physical inspection is required to determine if the 'marking' on the rim is a superficial scuff or a structural chip, which would reduce the value by 50%. Furthermore, identifying the specific manufacturer (e.g., Blenko vs. generic import) would require checking the weight, base wear patterns, and glass UV reactivity. No scientific testing has been performed to verify chemical composition.
