AI Appraisal Estimate

This is a large, hand-blown or mold-blown glass goblet featuring a distinct teal or aqua blue-green coloration. The item is characterized by a tulip-shaped bowl that flares slightly at the rim and tapers down to a short, thick, baluster-style stem with a rounded knop. The circular foot is wide and flat, providing stability for the high-volume bowl. The glass exhibits a translucent quality with excellent light refraction, though slight internal swirl marks are visible, suggesting a mid-to-late 20th-century production, possibly in the style of West Virginia glassmakers like Blenko or Kanawha. The color saturation is deeper at the base of the bowl and the stem where the glass is thickest. Regarding condition, the goblet appears to be in good vintage state with no visible chips or cracks. There are minor surface scratches consistent with shelf wear on the underside of the base. The piece lacks visible manufacturer's marks or signatures, but the craftsmanship shows a smooth fire-polished rim and a seamless transition from stem to base, indicating a quality mass-market or mid-tier decorative glassware production. The overall aesthetic aligns with Mid-Century Modern or retro 1970s kitchenware styles.

I have conducted a visual examination of the Teal Glass Stemmed Goblet. The item presents as a characteristic mid-20th-century decorative piece, likely produced between 1960 and 1975. The tulip-shaped bowl and baluster stem are indicative of American decorative glass houses such as Kanawha or Rainbow Art Glass, though the absence of a pontil mark or maker's label makes a definitive attribution to a higher-end firm like Blenko less certain. The condition is good, with only minor shelf wear on the base, which is expected for 'moderate-use' vintage glassware. The current market for Mid-Century Modern (MCM) glassware remains steady, though values for unsigned, mold-blown pieces have plateaued compared to larger architectural glass forms. This specific teal/aqua colorway is highly desirable among collectors of retro kitchenware and 'Viking-style' decor. Comparables for similar unbranded glass goblets of this size typically hammer at online auctions for $35 to $55, with retail boutique pricing reaching $75. Factors impacting the value include the transparency of the glass and the vibrant hue, which increases decorative appeal. However, the lack of a signature or original foil sticker limits its ceiling as a collectible asset. Limitations: This appraisal is based solely on visual photographic evidence. A physical inspection is required to confirm the presence of a fire-polished rim versus a ground rim and to check for internal 'sick glass' (chemical instability). To verify the manufacturer, I would need to compare the exact weight and dimensions against factory catalogs from the 1970s. Provenance documentation or original packaging would significantly enhance the certainty of this valuation.
