This striking centerpiece bowl exhibits a commanding sculptural presence, characterized by its deep, light-absorbing obsidian hue and substantial glass weight. The form features a bold, undulating scalloped rim that creates a rhythmic play of shadow and reflection across its polished surface. Supported by a faceted hexagonal pedestal, the object balances architectural geometry with organic fluid lines, making it a compelling focal point for a refined interior.
Attribution & Period
Stylistically aligned with American Mid-Century glass production, this piece is consistent with the high-quality press-molded techniques utilized by firms such as Tiffin or Fostoria during the 1940s. The dense "black" glass—technically a very deep purple known as black amethyst—and the precise faceting of the stem are characteristic of mid-century decorative arts from the Ohio River Valley region. No factory mark is observed, which is typical for glass of this era originally identified by paper labels.
Based on the hexagonal pedestal stem and the specific "scalloped" rim profile combined with the weight of the glass, this piece is most defensibly attributed to the 1940s.
While black glass had a surge in the 1930s (Depression era), the transition toward bolder, more geometric architectural stems like this hexagonal design became a hallmark of "Elegant Glass" manufacturers (like Tiffin and Fostoria) as they moved into the early 1940s. By the late 1950s, styles shifted toward more "free-form" or "organic" ruffles (like Viking Glass), making the structured, rhythmic scallops on your piece a classic representation of early-to-mid 1940s American glass design.

Ruby-to-amber cut crystal pedestal vase with a flared trumpet rim, deeply faceted stem, and dramatic starburst foot. The body is decorated with floral/botanical engraving (appears wheel-engraved or acid-etched), giving this piece the classic Bohemian jewel glass presencehigh sparkle, substantial weight, and strong light play from every angle.
Attribution & Period
Based on form, cutting style, color combination, and engraving technique, this vase was most likely produced circa 1950s1970s in Bohemia / Czechoslovakia (now Czech Republic). This period aligns with postwar Central European export crystal, where colored bowls paired with heavy cut stems and decorative engraving were widely produced for the international market.
UV reactivity
This vase reacts under a 365nm black light, producing a warm orange-to-red fluorescence as shown in the first image. This response is consistent with selenium-based ruby glass colorants, which may include cadmium compounds historically used in colored crystal production. The exact activator cannot be confirmed without laboratory testing, and the piece is described accordingly.
Authenticity & Construction
This form and execution strongly align with 20th-century Bohemian / Czech decorative cut crystal. The combination of a colored ruby bowl, amber-toned crystal, heavy mitre-cut faceting, and engraved decoration is characteristic of Central European export glass produced from the mid-century into the late 20th century. Comparable examples are often associated stylistically with Bohemian houses such as Egermann or Moser; however, this piece is unmarked and is therefore attributed by style only, not by maker.
Condition (read carefully)
This piece is not mint and is priced with full transparency. Three cracks around the base/foot, visible in close-up images Chips along the base/foot edge, as shown Upper bowl and decorative surfaces present well; engraving remains attractive Damage is confined to the foot.

A sculptural mid-century pedestal comport defined by its architectural octagonal form and luminous cased coloration. The softly opalescent blush bowl appears suspended above a radiant coral foot, creating a subtle internal glow that intensifies under directional light. The satin “sandy” finish diffuses the surface, giving the piece a refined, almost alabaster-like presence while retaining the warmth of post-war American art glass.
Balanced, symmetrical, and quietly dramatic, this is a form rooted in mid-century optimism—where geometry met atmosphere and decorative objects were designed to anchor a room. The interplay between the glowing base and diffused upper body gives the piece depth well beyond its scale, making it equally suited to minimalist interiors and layered, moody environments.
Attribution & Period
American art glass comport, Mid Century period, circa 1945–1965. The satin “sandy” surface, glowing cased coloration (opalized blush bowl over a vivid coral/orange base), molded octagonal plan, and visible vertical mold seam strongly indicate mid-20th century American pressed and mold-blown production in the tradition of Fenton Art Glass, Viking Glass, or a comparable U.S. art glass house. No signature present. Attribution is stylistic and construction-based.
Dimensions & Weight
Diameter: 9 inches
Height: 2.75 inches
Base diameter: 3.5 inches
Each of the 8 sides: approximately 3.5 inches
Weight: 1.3 lbs
Condition
Excellent condition. No scratches, no chips, no cracks. Surface retains an even satin finish throughout. A visible mold seam is present, consistent with mid-century pressed/mold-blown production and not a condition issue. Interior and foot rim are clean and well-preserved.
Authenticity & Construction
This piece was formed in a multi-part mold, evidenced by the vertical seam visible in close inspection. The octagonal footprint and scalloped rim were integrated into the mold design rather than tooled freehand.
The coloration suggests cased glass construction: a soft opalescent pink upper layer fused over a more intensely pigmented coral/orange base. Under light, the foot glows with a saturated warmth while the bowl reads as diffused and architectural. The satin “sandy” surface is achieved through acid-etching or controlled surface treatment, a technique widely employed in American art glass factories during the mid-century era to soften form and enhance light diffusion.
The pedestal form and controlled symmetry align with post-war American decorative glass production, when companies such as Fenton and Viking explored sculptural yet accessible table forms in glowing pastels and sunset hues. While it shares characteristics with Fenton’s satin lines and Viking’s architectural silhouettes, there is no signature or original label; therefore, it is conservatively attributed to American mid-century production.
A coordinating elongated tray (shown in one image) is available separately.
Placement
Ideal as a low centerpiece, sculptural fruit bowl, or pedestal display for florals or objects. Its glowing coral foot and diffused blush bowl perform especially well under directional lighting or candlelight, where the base radiates warmth upward through the body. Works equally in restrained modern interiors and layered Art Deco-inspired settings.

This commanding hand-blown vessel is a definitive expression of Finnish modernist glass artistry, featuring a deeply saturated cranberry core that radiates into a luminous amber rim. The architectural, wide-flaring silhouette is elevated by an intentional field of controlled internal air inclusions (bullicante), creating a rhythmic optical play that captures and refracts light. Its substantial mass and sophisticated tonal transitions from magenta-toned cranberry to golden amber reflect the peak of the Scandinavian studio glass movement.
Attribution & Period
The base features a professionally engraved presentation signature and date: "S. Kiitos 69." The "S" prefix denotes Suomi (Finland), while "Kiitos" identifies the piece as a bespoke commemorative or diplomatic gift commissioned from a premier Finnish glassworks—likely Riihimäki or Kumela—during the 1969 revival of experimental studio techniques. The elongated, stylized script is the hallmark of a master factory engraver.
Material & Fluorescence
The glass composition utilizes traditional 1960s mineral oxides, confirmed by a dual-spectrum UV reaction. Under 365nm light, the amber transitions exhibit a characteristic manganese-yellow glow, while the cranberry core reveals a vibrant cadmium-orange fluorescence, authenticating the piece’s mid-century chemical "recipe" and high-quality mineral content.
Condition & Construction
Condition: Excellent. The glass remains brilliantly clear with a high-polished luster. The base shows age-appropriate shelf contact consistent with its five-decade history as a curated object.

This substantial hand-formed glass sculpture commandingly interacts with light through its deeply saturated cobalt core and high-clarity crystal casing. The form is defined by sweeping, asymmetric rim articulations that create a sense of arrested motion, moving beyond functional vessel logic into pure sculptural expression. Under 365nm UV light, the outer casing reveals a vibrant neon-green fluorescence, indicating the presence of uranium oxide—a technical characteristic that adds a hidden, secondary dimension to its visual profile.
Attribution & Period
1960s. The technical execution—specifically the heavy "sommerso" style casing and the inclusion of UV-reactive agents—is stylistically aligned with mid-century Bohemian and Scandinavian studio traditions. The deliberate weighting of the base and the precision of the internal color suspension suggest a high-level production house, likely from the Zelezny Brod (ZBS) or Sklo Union regions, where experimental glass chemistry and organic "free-form" shaping were hallmarks of the era.

Excellent condition. No cracks, chips, or scratches observed. Surface remains clean and consistent with original satin finish. Minor internal textural variation near the base—visible as a ripple effect from the hot glass forming process—documented in close-up imagery and inherent to manufacture.
Authenticity & Construction
Hand-formed glass, likely free-blown and shaped while hot, then finished with a satin acid-etched or sandblasted surface. The subtle ripple near the base reflects the natural movement of molten glass during shaping, supporting an authentic hand-worked process rather than pressed production. The even coloration and soft iridescence indicate controlled finishing typical of higher-quality art glass.
Placement
Ideal as a centerpiece on a dining or cocktail table, or as a sculptural accent on a console, credenza, or open shelving. Works particularly well in minimalist, Scandinavian, and contemporary interiors where material presence and form are prioritized over ornament.

A compact yet visually powerful Murano glass bowl defined by its dense, jewel-toned red core suspended within a thick, clear casing. The form is fluid and biomorphic, with softly undulating edges that create shifting reflections and depth from every angle. Controlled air bubbles (bullicante) punctuate the surface, adding texture and optical complexity. Light passes through the clear exterior and refracts into the saturated interior, producing a luminous, almost molten effect. Despite its modest scale, the piece carries strong sculptural weight and presence.
Attribution & Period
Consistent with Murano, Italy glass production, 1960s. The sommerso technique (submerged colored core encased in clear glass) combined with controlled bullicante inclusions and thick, polished casing aligns with mid-century Murano studio practices. No factory mark observed; attribution remains visual rather than documented.

This sculptural emerald green art glass bowl presents a striking organic silhouette defined by sweeping folded lobes and a radiant internal bubble field. The heavy, luminous glass interacts dramatically with light, creating shifting tones from deep emerald to near-clear highlights along the curling rim. Viewed from above, the bowl reveals a rhythmic radial structure that reads almost floral or biomorphic in composition. The piece functions as a decorative centerpiece as much as a vessel, offering strong visual presence in both natural and artificial light.
Attribution & Period
Unmarked Czech art glass example, stylistically aligned with Central European studio and factory production of the 1960s. The saturated emerald coloration, controlled internal bubble inclusions, and thick sculptural mass are characteristic of Czech pressed and mold-assisted art glass from the mid-century period. The flowing organic rim and biomorphic symmetry reflect design language seen in Bohemian decorative glass works produced for export during this era. No factory mark was observed; attribution remains visual rather than documented.
Dimensions & Weight
Height: 3 in
Width / Diameter: 6.5 in
Depth / Base Diameter: 2 in
Weight: 2.206 lbs
Condition
Very good condition. No cracks, hairlines, chips, or repairs observed. Minor surface wear and light scratches present on the base consistent with normal shelf contact. Internal bubbles and inclusions are inherent to the manufacturing process. UV light images show optical color shift between green and blue due to glass thickness and light refraction, not damage.
Authenticity & Construction
Constructed from thick molded art glass with controlled bubble inclusions distributed throughout the body of the piece. The bowl was likely produced using a mold-assisted hot glass technique in which molten glass containing trapped air inclusions was formed into the sculptural radial mold, then hand-finished at the rim. The substantial weight and optical density confirm a solid art glass construction rather than thin blown glass.
Placement
Ideal as a sculptural centerpiece on a dining table, console, or cocktail table where directional light can activate the color depth and internal bubble structure. It also works effectively in layered interior compositions with stone, lacquer, or metal surfaces where the luminous emerald glass provides contrast and visual movement.

This striking mid-century centerpiece exemplifies the fluid, organic modernism that defined Swedish art glass in the 1950s. The piece features a dramatic "wing" profile, utilizing a complex cased-glass technique that creates an inner core of vibrant pigment suspended within a substantial layer of optical-grade clear glass. Its sculptural presence is amplified by its weight and scale, capturing and refracting light through its varying thicknesses and elegant, biomorphic curves.
Attribution & Period
by Paul Kedelv for Flygsfors
The piece is a definitive example of the "Coquille" series, designed by Paul Kedelv (1917–1990) for the Flygsfors glassworks in Sweden. The signature on the base is a documented factory mark for Flygsfors, dated 1956. Kedelv, who trained under the legendary Orrefors masters, launched the Coquille line in 1952; it remains his most celebrated work, characterized by these shell-like, pulled forms and the "Sommerso" style layering of colors.
Dimensions & Weight
Height: 5 1/2 inches
Width / Diameter: 11 1/4 inches
Depth / Base Diameter: 2 3/4 inches
Weight: 4.15 pounds
Condition
Excellent condition. The glass retains high clarity and luster. No chips, cracks, or significant fleabites are observed on the upper rim or body. The base exhibits light, age-appropriate shelf wear and faint surface scratches consistent with a 70-year-old decorative object. Minor internal bubbles (seeds) are present from the original hand-blowing process, typical of mid-century studio glass.
Authenticity & Construction
Hand-blown in Sweden using the cased glass technique. The artisan began with a core of colored glass, which was then dipped into clear molten glass and manipulated by hand using shears and jacks to pull the elongated "wings." The significant depth of clear glass at the base (3/4 inch) and edges (1/4 inch) is a hallmark of high-quality Flygsfors production, providing the necessary ballast and structural integrity for such a top-heavy, expressive form.
Placement
The sculptural silhouette and horizontal orientation make this an ideal centerpiece for a low-profile credenza, a mid-century teak dining table, or a sunlit architectural niche where the glass can interact with natural light.

This sculptural green art glass pitcher presents a bold, architectural presence defined by its tiered, rounded body and elegantly arched handle. The luminous green glass shifts in tone from pale celadon to saturated emerald as it interacts with surrounding light, creating strong visual depth and movement. A delicately acid-etched floral and leaf motif encircles the central belly, introducing refined surface detail against the smooth molded form. Under UV 365 light, the vessel exhibits a vivid fluorescence characteristic of uranium glass, adding a dramatic collector feature. The result is a visually compelling decorative object that performs equally well as art glass sculpture or refined tabletop accent.
Attribution & Period
Circa 1930s; Unmarked decorative arts example, best described as a Central European uranium glass pitcher, stylistically aligned with Czech and Bohemian glass production of the interwar period.
The molded tiered body, integrated spout form, acid-etched botanical band, and uranium-green coloration correspond closely with decorative glass produced in Central Europe during the early twentieth century. Similar uranium glass vessels were produced in Bohemia and surrounding regions where pressed or molded forms were frequently enhanced with acid-etched ornamentation. No factory mark or label is observed on the base; attribution therefore remains visual rather than documented.
Dimensions & Weight
Height: 8.5 in
Width / Diameter: 6 in (widest measurement including handle and spout)
Depth / Base Diameter: 3.5 in base diameter
Weight: Not provided
Mouth diameter: 4 in
Condition
Excellent vintage condition. No scratches, chips, hairline cracks, or repairs observed. Surface remains glossy and clean with only minor base wear consistent with careful age and storage. Small internal bubbles and subtle mold characteristics typical of period glass production may be present and are inherent to the manufacturing process.
Authenticity & Construction
The vessel was produced using a molded glass form that created the distinctive three-tiered body profile and integrated spout geometry. The handle was applied while the glass remained hot, fusing seamlessly to the body. Following formation, the floral and leaf decoration was acid-etched into the surface, creating a soft matte motif that contrasts with the polished glass surface.
The vivid green coloration and strong fluorescence under UV 365 light indicate the presence of uranium oxide within the glass composition, a material commonly used in early twentieth-century European glassmaking to produce uranium or vaseline glass. This uranium content causes the glass to emit a bright green glow under ultraviolet light, a defining characteristic sought after by collectors.
Placement
This pitcher works exceptionally well as a sculptural decorative object on a dining credenza, bar cabinet, console table, or illuminated display shelf. When placed near natural light the glass reveals layered tonal depth, while UV display lighting dramatically activates the uranium fluorescence. The piece integrates easily into Art Deco interiors, modern decorative settings, and curated glass collections.
