AI Appraisal Estimate

This is a vintage Art Deco style green glass bowl, characteristic of uranium (Vaseline) glass due to its distinct translucent lime color, which typically glows under UV light. The bowl features a wide, flat rim with intricate geometric wheel-cut or pressed designs consisting of semi-circular arches, cross-hatching, and fan-leaf motifs. The center is recessed with a tiered, concentric circular base. In terms of construction, it is a thick-walled pressed glass piece, likely dating from the 1920s to 1940s. The surface appears mostly clear, though some light surface scratches and minor 'flea bites' or tiny chips may be present along the outer rim edges, consistent with age and use. There are no obvious major cracks or repairs visible. The matte-etched texture of the pattern contrasts with the smooth, polished clarity of the center and extreme outer edge. The quality of the pressed design suggests a mass-produced but high-quality decorative piece from a major glass manufacturer of the Depression era, such as Anchor Hocking, Hazel-Atlas, or Federal Glass.

Based on my visual examination of this Art Deco green uranium glass bowl, I have identified it as a representative piece of Depression-era tableware, likely produced between 1930 and 1940. The geometric wheel-cut patterns and lime-green hue are indicative of glass containing uranium oxide, which I would expect to exhibit strong fluorescence under a 365nm UV light. The condition appears to be 'Good to Very Good' for its age; while the clarity remains high, the noted 'flea bites' and surface scratches are common for pressed glass of this vintage and slightly detract from the value. Market demand for uranium glass remains steady among 'glow' collectors, though mass-produced pieces like this from manufacturers like Hazel-Atlas or Federal Glass are relatively abundant. Comparables for 10-12 inch centerpieces in this style typically realize between $40 and $70 at auction. Factors limiting the value include the lack of a specific prestigious maker's mark and the presence of minor rim abrasions. Importantly, this appraisal is based on photographic evidence only. To fully authenticate the piece and finalize this valuation, I would require an in-person physical inspection to confirm the absence of hairline fractures, verify the weight and tactile quality of the glass, and perform a Geiger counter test or UV light test to confirm the presence of uranium. Without provenance documentation or a confirmed manufacturer ID, this valuation assumes the piece is an original period production and not a later 1970s reproduction.
