AI Appraisal Estimate

This is a vintage pressed glass storage jar, likely dating from the 1930s Depression-era. The item is crafted from a pale green glass, often referred to as 'uranium glass' or 'vaseline glass,' which typically exhibits a fluorescent glow under ultraviolet light. Physically, the jar features a cylindrical body with a slightly flared rim and a matching flat-topped lid with a small central knob finial. The glass contains numerous internal air bubbles (seeds) and straw marks, which are characteristic of mass-produced machine-made glass from the early 20th century. Notable features include subtle horizontal ribbing near the collar and a molded base. The condition appears to be fair to good; there is visible surface cloudiness or 'sick glass' syndrome, indicating some chemical etching or hard water deposits from long-term use. There are no major cracks visible, but minor flea bites may exist along the inner rim. This style is consistent with utility kitchenware produced by companies like Hazel-Atlas or Federal Glass. The craftsmanship is functional rather than decorative, representative of mid-market household goods of the period.

Based on my examination of this green pressed glass apothecary jar, I have identified it as a classic piece of Depression-era utility ware, likely produced by the Hazel-Atlas Glass Company or a contemporary competitor circa 1930-1935. The pale green coloration and characteristic inclusions, such as internal seeds and straw marks, are consistent with high-volume production techniques of that period. Regarding condition, the 'sick glass' syndrome—a permanent chemical leaching of the glass—is a significant detractor. While common in utilitarian kitchenware, this cloudiness cannot be removed through standard cleaning and negatively impacts the aesthetic value. ThePresence of flea bites along the rim is characteristic of age but dictates a 'Fair' to 'Good' condition rating rather than 'Excellent' or 'Mint.' The market for Depression glass remains stable but is currently saturated with common utility shapes. While uranium glass collectors drive some demand due to the material's fluorescent properties, the lack of a rare pattern or pristine clarity limits its upside. Comparables for similar functional jars in this condition typically settle in the mid-double digits. Important Limitation: This appraisal is based solely on digital images. A definitive valuation would require an in-person inspection to confirm the depth of the surface etching and a UV light (365nm) test to verify the concentration of uranium dioxide. Authentic provenance, such as a documented history of ownership or original catalog placement, would be required to elevate this from a general 'utility jar' to a specific collector's piece. Final authentication depends on verifying that the cloudiness is not surface grime, which could slightly improve the valuation if cleanable.
