AI Appraisal Estimate

This is a low-footed glass compote or tazza, likely made of high-lead crystal, consistent with the optical clarity and design language of Steuben Glass. The piece features a shallow, wide-rimmed platter or bowl held by a decorative stem. The stem is notable for its 'twist' or 'entwined' construction, a labor-intensive glass-forming technique where multiple ribbons of hot glass are fused and rotated to create a helical, rope-like effect. This element suggests mid-20th-century American craftsmanship, potentially designed under the influence of notable Steuben designers like George Thompson or Walter Teague. The crystal displays a high level of brilliance despite being covered in a layer of environmental dust. The foot is flat and circular, providing a stable base that balances the wide diameter of the upper bowl. Regarding condition, there are visible surface scuffs and light scratches on the top plane of the glass, common with age and use. There are no immediate signs of chips or deep cracks, though the piece requires a thorough cleaning to reveal the true clarity of the crystal. While no signature is visible in the photograph, Steuben pieces of this era are typically diamond-point signed 'Steuben' on the edge of the foot. The overall silhouette is elegant and minimalist, characteristic of the Art Deco transitioning into the Modernist periods.

I have virtually examined this low-footed crystal tazza. Based on the high-lead content brilliance and the complex twisted stem construction, this piece is highly consistent with Mid-Century Steuben Glass, specifically the high-quality designs produced during the George Thompson era (circa 1940-1960). The intricate entwined stem is a hallmark of Steuben's technical mastery, distinguishing it from lower-tier glassmakers. The condition shows surface scuffing and dust accumulation, which are typical for utilitarian decorative objects of this age; however, the lack of significant chips or 'flea bites' on the wide rim preserves much of its value. The market for mid-century Steuben remains stable, though prices fluctuate. Comparable pieces from the same era currently realize between $400 and $700 at auction and through specialist dealers. The value is restrained slightly by the visible surface wear but bolstered by the classic, elegant silhouette. Authenticity cannot be 100% confirmed without a physical inspection to locate the 'Steuben' diamond-point signature, usually found on the underside of the base. Furthermore, an in-person examination under a UV light would be necessary to confirm the specific fluorescence associated with Steuben's proprietary crystal formula. For a definitive valuation, I would also recommend professional cleaning to assess if the surface scratches can be buffed or if they impact the optical clarity. Provenance documentation, such as the original gray flannel bag or presentation box, would increase the upper-end estimate.
