AI Appraisal Estimate

These two vessel forms appear to be hand-blown art glass with a frosted or 'Scavo' style finish, designed to emulate the corroded texture of ancient archeological glass. The glass is a smoky, translucent brown featuring rhythmic, pulled trailing decoration in a darker, almost black tone. This aesthetic is stylistically consistent with late 20th-century Italian glass designs, specifically those produced by Seguso or similar Murano-based glass houses. The larger vase has an elongated, slender neck terminating in a flared, irregular rim, while the smaller vase mirrors this bulbous-base form on a shorter scale. The surfaces have a textured, matte quality that suggests a post-manufacture treatment or chemical etching. No maker's marks or signatures are visible in the provided image; therefore, an attribution to a specific studio or artist remains a hypothesis subject to physical examination for acid stamps or inscriptions. The craftsmanship appears to be of high quality, with fluid line work and consistent graduation in color. Both pieces appear to be in good condition with no visible chips or cracks from this angle.

Based on my examination of the provided image, these two vessels appear to be high-quality hand-blown art glass featuring a 'Scavo' finish. I am analyzing these as a hypothesis that they were produced in the late 20th century, potentially by a Murano-based glass house such as Seguso, given the rhythmic trailing and archeological aesthetic. However, I cannot verify the manufacturer or age from a photo alone; I would need an in-person physical inspection to search for acid stamps, signatures, or specific glass-working techniques to support this attribution. The value estimate of $400 to $700 is based on the assumption that these are mid-to-late century Italian glass pieces in excellent condition. Items of this type currently enjoy a stable market among collectors of Mid-Century Modern and Post-Modern decor, where the 'Scavo' texture is particularly desirable. Please note that if these were to be definitively identified as unattributed contemporary decor or modern reproductions 'in the style of' Murano, the value would likely decrease to a range of $100 to $200. Conversely, if scientific testing or provenance documentation were to link these to a specific master glassblower, the value could exceed the current estimate. To confirm authenticity and a more precise valuation, one would need to verify the source of the chemical etching and examine the pontil scars for evidence of hand-tooling consistent with period Italian production.
