AI Appraisal Estimate

This is a vintage footed vase crafted from translucent light green glass, characterized by its distinct optic ribbing. Based on the yellowish-green tint and glowing properties visible, it is identified as 'Vaseline' or Uranium glass, which contains trace amounts of uranium oxide that react under UV light. The vase features a flared, wide rim with a rounded lip, a bulbous body with wide vertical optic ribs that catch the light, and a tapered base resting on a circular, stepped pedestal foot. This specific style and color are highly characteristic of the Tiffin Glass Company or similar American glass manufacturers such as Westmoreland or Hazel-Atlas, typically dating from the late Depression era through the 1940s. The construction shows high-quality mold-blown techniques with a polished finish. In terms of condition, the glass appears clear with no immediate evidence of clouding or sickness. There are minor surface scratches consistent with age and shelf wear on the underside of the base. The piece lacks a visible maker's mark, which is common for glassware of this period, often identified by its specific silhouette and the 'optic' pattern. Its substantial size and the vibrant response to UV (blacklight) make it a desirable collector's piece of Art Deco era utilitarian glassware.

I have conducted a visual examination of this footed optic rib vase, which exhibits the characteristic 'canary' or 'uranium' green coloration consistent with 1930s-1940s production. The optic ribbing is well-defined, and the stepped circular foot displays the structural integrity associated with Tiffin Glass Company's Depression-era output. Based on the provided imagery, the condition appears excellent with good clarity and no visible 'glass sickness' or significant chipping, though internal micro-bubbles suggest a period-correct mold-blown process. The market for uranium glass remains stable, driven by the 'glow' factor under UV light; however, the lack of a maker's mark and the relative abundance of optic-patterned utility glass from this era keep the valuation within the mid-market range. Comparables for similar Tiffin pieces generally fetch under one hundred dollars unless they represent rarer forms or larger centerpiece bowls. This item's value is bolstered by its aesthetic appeal to Art Deco and 'Glow' collectors. Please note that while the visual indicators strongly support authenticity, a definitive appraisal is limited by the digital format. A physical inspection is required to check for 'flea bites' along the rim, verify the exact weight and density, and search for a polished pontil mark or specific mold seams. Full authentication would ideally involve a Geiger counter reading to confirm the presence of uranium oxide and provenance documentation tracing the item to a specific regional glassworks collection.
