AI Appraisal Estimate

This item is a rectangular, covered refrigerator dish made of bright, translucent green glass, characteristic of uranium glass (also known as Vaseline glass). The dish appears to have a square or slightly rectangular base with straight, paneled or ribbed sides which run vertically along the length of the dish, giving it a somewhat Art Deco aesthetic. The lid is also made of the same distinctive green glass and features a flat top surface adorned with horizontal raised ribs or fluting, adding to its visual interest and possibly providing a non-slip surface, or simply for decorative appeal. The overall construction suggests a molded glass manufacturing process. The vibrant green color is a key indicator of uranium glass, which glows under blacklight due to the inclusion of uranium dioxide. Visible condition details suggest some age and use; there are some minor surface scratches and possibly some light scuffing on both the lid and the base, consistent with normal wear for a vintage item. There are no immediately apparent chips, cracks, or significant damage, though a thorough inspection would require handling. The craftsmanship appears to be typical of early to mid-20th century mass-produced glassware, focusing on practicality with a touch of decorative flair. This type of glassware was commonly used for food storage in refrigerators during its era. The item likely dates from the 1920s to the 1940s, a popular period for uranium glass production.

Based on my visual examination of the provided image, this green glass refrigerator dish with a matching lid is indeed characteristic of uranium glass, often referred to as Vaseline glass, due to its distinctive bright, translucent green hue. The paneled or ribbed sides and the fluted lid suggest an Art Deco influence, placing its likely manufacturing period within the early to mid-20th century, specifically the 1920s to 1940s, a peak era for such glassware. The green coloration, as indicated, is a strong visual marker for uranium content, which would fluoresce under black light. The overall construction points to a molded glass process, typical for mass-produced utility items of that period. Condition-wise, I observe minor surface scratches and light scuffing on both the lid and base, consistent with normal wear and tear for a vintage item used for food storage. Crucially, I see no immediate evidence of chips, cracks, or significant damage from the image. However, a thorough in-person inspection would be required to confirm this and assess any less obvious flaws. In terms of market conditions, uranium glass items, especially practical pieces like refrigerator dishes, retain a steady, though not exceptionally high, demand among collectors of vintage glassware and specific uranium glass enthusiasts. Comparables on online marketplaces and at antique shows typically fall within a modest range for items without significant maker's marks or exceptional rarity. This specific design appears functional and decorative but not unique enough to command a premium. Rarity is moderate; while not mass-produced today, these dishes were common in their time. Factors impacting value include the positive identification as uranium glass (which adds a collectible aspect), the complete set with the lid, and the generally good apparent condition. The primary limitation in authenticity verification from images alone is the inability to perform a blacklight test to definitively confirm uranium content, which is a key characteristic of Vaseline glass. An in-person examination would also allow for a tactile assessment of condition, precise measurement, and searching for any manufacturer's marks. Provenance documentation would be exceptional but is rarely available for such utilitarian items. Considering these factors, I appraise this Uranium Glass Refrigerator Dish with Lid at a value of $40-70.
