Stained Slag Glass Octagonal Form, Marbled Azure and Cobalt Tones

US$675.00

This handcrafted octagonal vessel possesses a commanding sculptural presence, defined by the striking contrast between its marbled sky-blue perimeter and a deep cobalt "water-textured" base. When illuminated, the slag glass panels diffuse light with a soft, ethereal glow, transforming the object from a geometric centerpiece into a vibrant light-filtering sculpture. Its versatile design allows it to function with equal elegance as a sophisticated decorative bowl or a distinctive architectural light shade for a pendant or floor lamp.

Attribution & Period

Unmarked Decorative Arts Example

Late 20th Century (1970s–1980s)

The construction is stylistically aligned with the studio craft movement, utilizing the copper foil technique popularized by Tiffany but interpreted through a Mid-Century geometric lens. The use of marbled slag glass paired with textured "cathedral" glass at the base is consistent with high-quality artisanal production from this era. The polished brass rim and pewter-toned solder joints indicate a piece designed for both durability and refined interior display.

Dimensions & Weight

  • Height: 4.5 inches

  • Width / Diameter: 12 inches (Top Opening)

  • Depth / Base Diameter: 8.75 inches

  • Weight: 2.392 lbs

Condition

The piece is in excellent vintage condition with a polished luster to the brass components. A single hairline crack is present on one of the marbled glass side panels; it is stable and remains barely perceptible under standard lighting conditions, not detracting from the structural integrity or the overall aesthetic of the form.

Authenticity & Construction

This piece was meticulously assembled by hand using traditional stained glass techniques. Each of the ten panels is individually cut and encased in brass channeling at the rim, then joined at the seams with heavy-lead solder (finished in a pewter patina). The base features a rare "ripple" or "water-texture" cobalt glass that creates a dynamic sense of movement when viewed from above or when light passes through the bottom of the vessel.

Placement

This vibrant blue form is ideal for a sunlit console table where the natural UV rays can activate the glass, or as a focal point on a minimalist dining table. It would also serve as a spectacular replacement shade for a high-end brass floor lamp or a custom-wired ceiling pendant in a contemporary or Hollywood Regency-inspired interior.

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.
