AI Appraisal Estimate

This is a decorative hand-blown art glass bowl featuring a distinctive trilobed or free-form undulating rim, characteristic of Mid-Century Modern organic design. The piece is constructed with a 'fazzoletto' style influence, exhibiting a multi-layered glass technique. The exterior is a solid, opaque white (latte) cased glass, while the interior displays a vibrant seafoam green transparent base. This interior surface is decorated with a 'macchia' or splatter pattern consisting of suspended flecks and larger circular 'spots' in shades of amber, ochre, cobalt blue, and darker forest green. The execution suggests a 20th-century Murano origin, possibly by makers such as Fratelli Toso or similar Venetian workshops active in the 1950s-1970s. The bowl shows a smooth, high-gloss finish with a thick, heavy base that likely contains a polished pontil mark (not visible from this angle). The condition appears excellent with no visible chips, cracks, or heavy surface scratching, though typical shelf wear on the base would be expected for a vintage piece of this age. The craftsmanship is of high quality, evidenced by the even distribution of the decorative frit and the graceful, symmetrical folding of the three prominent lobes.

I have conducted a visual examination of the Mid-Century Modern trilobed splatter glass bowl. The piece exhibits characteristic traits of mid-20th-century Murano production, specifically the 'fazzoletto' (handkerchief) folding technique and 'macchia' (spotted) decoration. The casing of white latimo glass against a seafoam interior indicates high-quality Venetian craftsmanship. In the current decorative arts market, Fratelli Toso and similar Murano workshops enjoy steady demand from MCM collectors, though values are currently dictated by size and vibrancy of color. This three-lobed form is less common than standard round bowls, which slightly increases its desirability. Similar sold comparables for unattributed but high-quality Murano macchia bowls range between $200 and $450 depending on the retail venue. The condition appears to be excellent; however, without a physical inspection, I cannot verify the presence of 'flea bites' or the specific wear pattern on the base which helps distinguish vintage glass from modern reproductions. Furthermore, while the style is indicative of Fratelli Toso, the absence of a 'Murano Italy' foil label or an acid-etched signature limits a definitive attribution. For full authentication, I would require an in-person examination of the pontil mark to confirm it is polished and not molded, and I would seek any available provenance or original purchase records. This appraisal assumes the piece is free of internal heat cracks or contemporary repairs not visible in the provided image.
