Set of three sculptural pressed glass bowls defined by a sharply articulated octagonal silhouette and richly saturated amethyst tone. The geometry is precise and architectural, with crisp faceting that produces a controlled interplay of shadow, reflection, and internal refraction across each plane.
In ambient light, the glass presents as a deep purple with subtle tonal variation through the body. Under UV 365 lighting, the bowls exhibit a pronounced electric blue fluorescence—an inherent material response indicating the presence of manganese within the glass matrix. This dual-light behavior introduces a second visual register, elevating the set beyond standard pressed glass into a crossover category of decorative and reactive material.
Each bowl reads as both functional vessel and sculptural object, with a low, grounded profile and disciplined symmetry.
Attribution & Period
example consistent with North American pressed glass production, .c 1940s The molded construction, uniform wall thickness, and sharply resolved octagonal faceting align with transitional pre-war to early mid-century tableware.
The observed UV fluorescence supports the use of manganese as a decolorizing or clarifying agent, a characteristic consistent with glass formulations of the period.
Dimensions & Weight
Condition
Excellent condition. No chips, cracks, or repairs observed. Surfaces retain full gloss with minimal wear. Structurally sound throughout.
Authenticity & Construction
Pressed glass construction formed in a precision mold, producing consistent wall thickness and sharply defined facets. The clarity and edge definition reflect higher-quality production within the pressed glass category.
The UV fluorescence is inherent to the material composition and not a surface treatment. Under 365nm light, the glass emits a strong blue response, a phenomenon associated with manganese-bearing glass and increasingly recognized among collectors of early 20th-century glass.
Placement
Effective in both neutral and controlled lighting environments. Particularly suited for backlit or UV-lit display where the material response can be activated. Functions as a cohesive sculptural grouping or as individual accent vessels within a glass-focused installation.
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 early 20th-century design objects, definitive attribution may not be possible without original labels or factory records. Pricing reflects condition, material characteristics, decorative appeal, and current collector demand rather than guaranteed maker identification.
