AI Appraisal Estimate

This is a vintage two-piece covered butter dish manufactured by Indiana Glass in the 'Amberina' color palette, specifically for the Tiara Exclusives line. The item features the classic 'Sandwich' pattern, characterized by intricate scrolled floral and leaf embossing. The color exhibits a striking ombre effect, transitioning from a deep ruby red at the top finial and edges to a vibrant amber-yellow toward the base. This coloring is achieved by reheating specific areas of the glass containing heat-sensitive chemicals. The dish consists of a rectangular base with a wide, scalloped rim and a matching domed lid with a faceted geometric finial. The lid features vertical ribbing along the lower section, contrasting with the ornate floral presswork above. Given its production history, this piece dates roughly from the 1970s. The glass appears to be in good vintage condition with no visible chips or cracks, maintaining a high glossy luster typical of pressed glass from this era. The complex 'Sandwich' texture and the vivid color transition are key indicators of quality for this specific collectible line.

Based on my visual examination of the Tiara Exclusives Amberina Sandwich pattern covered butter dish, I find the piece to be a textbook example of 1970s-era Indiana Glass production. The color transition is exceptionally vibrant, showing a high degree of cadmium/selenite strike, which results in the desirable 'fire' transition from deep ruby to honey amber. The molding is crisp, suggesting it was pressed early in the mold's life cycle before the intricate scrollwork became blurred. The market for Tiara Exclusives remains stable but saturated. While the 'Sandwich' pattern is highly collectible, the Amberina colorway was produced in significant quantities compared to rarer colors like teal or sunset. Current market comparables for a butter dish in this specific color range between $40 and $60 in online auctions and specialty glass boutiques. The presence of the lid is crucial, as the finials are prone to chipping; this example appears to be in excellent vintage condition with no visible flea bites or 'sick' glass (calcification). Value is driven by the intensity of the red-to-yellow gradient; pieces with more 'ruby' coverage typically command the high end of the estimate. However, as this appraisal is based on digital images, I cannot verify the presence of internal heat checks, microscopic scratches, or the 'ring' of the glass which confirms structural integrity. A full authentication would require an in-person inspection under a long-wave UV light to observe the characteristic glow of Amberina glass and a tactile check for factory-second grinding marks on the base.
