Shell Aqua Pressed Glass Dishes, Manganese Glow, 1960s

This offering comprises a matched pair of shell-form decorative glass dishes, produced in the 1960s and executed in thick aqua-toned pressed glass. Each dish is modeled with deeply radiating spiral ribs that resolve into a tight central whorl, creating pronounced optical movement and a strong sculptural presence despite the shallow profile. The forms are crisply defined and highly symmetrical, characteristics consistent with postwar molded glass production rather than free-blown studio work. Close examination reveals controlled mold flow and uniform rib definition, visible in the documented macro images, confirming pressed manufacture while retaining a refined surface finish. The aqua coloration is cool and luminous, shifting subtly between blue and green depending on ambient light. Under ultraviolet examination, the glass emits a soft green fluorescence when exposed to 365 nm UV light, with no reaction under 395 nm. This behavior is consistent with manganese-bearing glass, historically used as a refining and decolorizing agent in mid-20th-century production. The UV response definitively excludes uranium content. The shell motif reflects the period’s interest in abstracted natural forms, translated here into functional sculpture. These objects read equally as decorative dishes or as stand-alone display pieces and are particularly effective when backlit or shown against dark surfaces. ⸻ Measurements (each) • Length: 10 inches • Width: 6 1/2 inches • Height: 1 inch Combined weight: 3.06 lbs ⸻ Condition Good vintage condition, consistent with age and use. • One dish exhibits a small, stable crack, clearly documented in the final image • No repairs observed • Light surface wear consistent with handling The crack does not compromise display integrity and has been fully disclosed. ⸻ Date & Attribution Mid-20th century, circa 1960s. Dating is supported by manufacturing method, glass chemistry, UV response, and design language consistent with decorative pressed glass produced during this period. No maker’s mark is present; the pair is presented unattributed, in accordance with responsible cataloguing standards. ⸻ Material & UV Disclosure Pressed (molded) glass with manganese content, confirmed by fluorescence under 365 nm UV light only. No uranium content indicated. ⸻ Decor / Collection Context Mid-Century Decorative Art Glass · Organic Modernism · Sculptural Glass ⸻ mid century decorative glass, manganese glass, UV reactive glass, shell form glass, pressed glass dishes, aqua glass, organic modern glass, sculptural glass objects, collectible glass, 1960s glass design, abstract natural form glass, display glass objects, decorative art glass, coastal modern decor, glowing glass, statement glass, modernist decorative glass, molded glass design, mid century shell glass, exhibition glass
