AI Appraisal Estimate

This is a Victorian-era pressed glass bowl, specifically identified by the embossed registration number 'Rd 252274' on the base, which dates the design to approximately 1895. The bowl measures 21.7 cm in top diameter and stands on a 7.7 cm base. It features a decorative pressed pattern resembling 'Daisy and Button' or hobnail geometric variations, consisting of interlocking diamonds and circular facets that provide high refractive brilliance. The base is finished with a radial starburst or sunburst pattern. A notable physical characteristic is the metal rim, likely silver-plated, which shows significant dark oxidation or tarnish consistent with age. Under 365nm UV light, the glass exhibits a distinct green fluorescence, confirming the presence of manganese used as a decoloring agent during the manufacturing process. The glass appears to be in good structural condition with no major chips visible, though there is typical scratching on the interior and base commensurate with domestic use. The metal rim shows surface wear and patina but remains firmly attached to the glass body. This piece serves as a fine example of late 19th-century British functional glassware, combining industrial glass molding techniques with the aesthetic of high-end cut crystal.

I have examined the digital documentation of this Victorian pressed glass bowl, identified by the British Registry number 252274. The design originates from late 1895, marking it as a quintessential example of mass-produced late-Victorian tableware. The 'Daisy and Button' variant pattern is well-executed, and the manganese-induced green fluorescence under 365nm UV light confirms the glass composition is consistent with the period's manufacturing techniques. The silver-plated rim exhibits heavy oxidation; while this patina confirms age, the loss of the original luster slightly impacts decorative appeal for the average collector. The structural integrity appears sound, though typical surface abrasions are noted. The market for Victorian pressed glass is currently saturated, with high supply and steady but modest demand. Values are driven by functionality and condition rather than rarity, as these were produced in high volumes. Comparable pieces frequently sell in the $40 to $70 range at regional auctions. While the visual evidence strongly suggests authenticity, this assessment is limited by the digital format. A physical inspection is required to check for 'flea bites' on the sharp edges of the pattern and to verify the hallmarks or manufacturer's stamps on the metal rim, which would further solidify provenance. Verification of whether the rim is sterling or electroplated is also recommended via a chemical acid test, as sterling mounts would significantly increase the valuation. I have assumed the rim is silver-plated based on the tarnish profile and the typical standards for this era of mass-market glassware.
