AI Appraisal Estimate

This is a vintage oval serving bowl manufactured by the Indiana Glass Company, featuring the recognizable 'Harvest Grape' pattern. The piece is constructed from heavy pressed glass in a translucent green color, often referred to as 'Tiara Green' or 'Avocado Green'. The design is characterized by an intricate embossed motif of grape clusters and textured leaves covering the underside of the vessel. The bowl features a distinct scalloped rim and is supported by four integrated, stump-like feet that elevate the main body. Measuring approximately 10 to 12 inches in length, this item reflects the mid-century modern aesthetic popular during the 1960s and 1970s. The glass contains various air bubbles and organic striations inherent to the mold-pressed manufacturing process of that era. There are no visible chips or significant fractures in the glass, though light surface scuffing and shelf wear on the bottom of the feet are present, which is consistent with age and previous utility. The craftsmanship demonstrates a high level of detail in the relief work, showcasing the mass-produced yet durable quality of American collectible glassware from the late 20th century.

I have examined the digital representation of this Indiana Glass Harvest Grape footed bowl in avocado green. Based on the visual evidence, the piece exhibits the characteristic mold lines and heavy pressed-glass construction associated with the Indiana Glass Company's production during the 1960s and 1970s. The 'Harvest Grape' pattern is highly recognizable and shows healthy relief in the grape clusters; the presence of air bubbles and striations are consistent with the original manufacturing standards of the period rather than defects. The condition appears to be 'Very Good,' as the lack of visible chips on the scalloped rim or feet suggests careful previous ownership. This specific pattern and color were mass-produced in high volumes, resulting in a saturated secondary market. Current demand is driven primarily by mid-century modern collectors and 'Boho-chic' decor enthusiasts rather than high-end investors. While this serves as a durable and attractive example of American glassware, its ubiquity limits its rarity. Note that this appraisal is based solely on images. A physical inspection is necessary to detect 'flea bites' or internal heat cracks not visible digitally. Authenticity is determined here by pattern recognition, but definitive verification would require physical measurement of weight and density to ensure it is not a contemporary reproduction, though few reproductions of this specific line exist due to the low profit margins of doing so.
