AI Appraisal Estimate

This is a handcrafted vintage art glass bowl featuring a distinctive organic, undulating rim commonly referred to as a 'freeform' or 'swung' edge. The piece is constructed with a dual-layered glass technique: the exterior is a solid opaque white glass, providing a clean and smooth contrast to the interior. The interior surface showcases a vibrant seafoam green base heavily decorated with a 'splatter' or 'confetti' pattern of amber, brown, and light blue glass inclusions. These dappled spots create a sense of movement and depth within the vessel. The bowl's shape is characterized by four soft lobes or waves that rise from a central well, suggesting it was hand-stretched while the glass was molten. No visible maker's marks or signatures are apparent in the image, though the style and materials are highly indicative of Murano glass production from Italy or American houses like Blenko or Chalet from the 1960s to 1970s. The condition appears sound with no visible chips or cracks, showing a glossy fire-polished finish and a slight natural patina indicative of age. The craftsmanship is high, with even distribution of color and a balanced, sculptural silhouette.

I have conducted a visual examination of the Mid-Century Modern Art Glass Splatter Bowl. The piece exhibits characteristic traits of mid-20th-century 'splatter' or 'confetti' glass, most likely originating from the Murano region of Italy, though American manufacturers like Blenko or Kanawha produced similar organic forms. The dual-layered (cased) construction with a white exterior (lattimo technique) and a seafoam interior with multi-tonal inclusions suggests a high degree of craftsmanship and deliberate color layering. The condition appears Excellent (EX), with the fire-polished rim and lobes showing no visible bruising, flea bites, or internal annealing cracks. The 'freeform' silhouette is well-balanced, indicating the glassmaker possessed significant skill in manipulating molten material. Currently, the market for MCM art glass remains steady, though values for unsigned splatter glass have stabilized below peak heights of the early 2010s. Comparables for unsigned 10-12 inch cased splatter bowls typically range from $100 to $200 depending on the complexity of the color palette. Factors impacting value include the desirable seafoam base and the lack of a pontil mark or signature, which prevents a definitive attribution to a specific maestro (e.g., Archimede Seguso). Authenticity from images alone is limited by the inability to inspect the base for 'wear patterns' or use a UV light to check glass chemistry. To finalize this appraisal for insurance purposes, an in-person inspection is required to verify the presence of a ground pontil or acid-etched mark, examine the base for age-appropriate shelf wear, and weight the piece to confirm lead crystal content.
