This substantial crystal vessel is a masterclass in geometric precision and material rarity, featuring a deep prismatic profile that commands the space. The glass possesses a remarkable luminous quality, exhibiting a vivid, neon-green fluorescence under ultraviolet light—a definitive characteristic of uranium-oxide-infused crystal. Its heavy, architectural base transitions into a refined faceted body, creating a sophisticated play of light and shadow that is as materially compelling as it is visually striking.
Attribution & Period
By Sebastian Marcen, 1970s. This piece is signed "S. Marcen" on the base, identifying it as the work of the Spanish mid-century designer Sebastian Marcen. Known for high-quality, heavy-gauge crystal produced in Spain, Marcen’s work is celebrated for its clean, modernist lines and exceptional density. While uranium glass is often associated with earlier decorative eras, Marcen’s utilization of the material in a faceted, Postmodern silhouette represents a rare and high-end intersection of classic glass chemistry and Mid-Century Spanish design.
Dimensions & Weight
Condition
Good condition. The glass is structurally sound with no chips, cracks, or repairs observed. The interior is clear and free of mineral staining. As is consistent with authentic hand-finished crystal of this age, the base displays honest shelf wear and micro-scratches where the maker’s mark is situated, serving as a testament to its age and original use.
Authenticity & Construction
This is a heavyweight, mold-blown crystal object with a hand-polished finish. The signature "S. Marcen" on the underside confirms its origin from the Spanish studio. The glass was formulated with uranium oxide, a traditional technique used to achieve its specific refractive index and signature UV response. The exceptional weight-to-size ratio (over one pound for a 4-inch vessel) confirms a high-lead content, ensuring the piece maintains the "ring" and brilliance of investment-grade crystal.
Placement
This sculptural object is a perfect addition to a curated bar cart, a brutalist shelving arrangement, or a dedicated collection of fluorescent minerals and glass. Its heavy base makes it an ideal functional piece for a low-profile executive desk, while its vibrant UV glow makes it a spectacular conversation piece for a contemporary vitrine equipped with blacklight accents.
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.
