A refined example of mid-century Central European art glass, this bowl presents a luminous cobalt blue core suspended within clear glass, creating a striking optical depth. The low, spherical form appears to rest on an almost invisible base, allowing light to pool and refract through the saturated color band. Subtle internal bubbles and fluid transitions give the piece a dynamic, sculptural presence. Compact in scale yet visually impactful, it functions as a deliberate decorative object rather than a purely utilitarian vessel.
Attribution & Period
Czech or Central European art glass, 1960s. The form is consistent with the Culbuto design language introduced within functionalist glass design, characterized by a spherical profile and visually minimized base. Construction details—including cased coloration, hand-blown formation, and a softly ground pontil—support Central European production. No factory mark observed; attribution remains visual rather than documented.
Collector’s Note:
Under UV analysis, the clear casing exhibits a faint, characteristic fluorescence indicative of Manganese—a traditional mineral agent used in 20th-century Czech glassmaking to achieve high optical clarity. This subtle 'glow' serves as a secondary hallmark of its mid-century artisanal origin
Dimensions & Weight
Condition
Excellent condition. No scratches, cracks, or repairs observed. Internal air bubbles present, consistent with hand-blown production. Base shows a smooth, lightly ground pontil with visible tooling marks, typical of studio or small-factory manufacture.
Authenticity & Construction
Hand-blown glass utilizing a cased (sommerso-type) technique, where colored glass is encased within a clear outer layer to create depth and optical clarity. The presence of controlled and uncontrolled air inclusions, along with the ground pontil, confirms manual production. The slightly irregular transitions and organic internal movement distinguish it from mass-produced or fully machine-finished examples.
Placement
Ideal as a sculptural accent on a cocktail table, bookshelf, or console. Works particularly well in modernist, minimalist, and curated interiors where material clarity and light interaction are emphasized. Its compact scale allows it to function as a standalone object or as part of a grouped glass composition.
STANDARD ATTRIBUTION & VALUE DISCLOSURE; This piece is described to the best of current scholarly and market knowledge. Any maker or regional attribution is based on visual analysis, materials, construction techniques, and documented stylistic comparisons. As with many MCM and antique design objects, definitive attribution may not be possible without original labels or factory records. Pricing reflects condition, quality, decorative appeal, and current collector demand rather than guaranteed maker identification.
