Description
Discover how Xandre LLC connects traditional Ryukyu craftsmanship with global collectors of contemporary Japanese art and luxury lifestyle objects. By sourcing directly from independent Okinawan studios, our curated catalog presents authentic glassblowing inspired by the sea, landscapes, and living culture of Okinawa.
Crafted by Glass Art Ai (グラスアート藍) in Yanbaru, Okinawa, this individually mouth-blown tumbler draws inspiration from the exceptionally clear waters and coral reefs of the Kerama Islands (慶良間諸島). The design translates the natural progression of the Kerama seascape into glass—from white coral sand and shallow turquoise water to deeper cobalt-blue ocean. A softly frosted surface diffuses the surrounding light, giving the vessel a calm, luminous appearance reminiscent of Okinawa's coastal waters.
Artistic Characteristics
- Kerama Ocean Gradient: An opaque milky-white upper section transitions through turquoise into a deep cobalt-blue base, reflecting the changing colors of the Kerama seascape from beach to reef to open ocean.
- Frosted Finish & Soft Texture: A smooth matte surface gently diffuses light while providing a tactile, understated finish.
- Balanced Cylindrical Form: The straight-sided silhouette provides a clean contemporary profile, while subtle vertical ridges near the lower section add texture and grip.
- Individual Studio Craftsmanship: Each tumbler is mouth-blown and shaped individually at Glass Art Ai, resulting in natural differences in the height, density, and movement of the color transitions.
- Studio Documentation: Accompanied by official Glass Art Ai studio literature describing the Kerama Lagoon concept behind the design.
Curator's Note
Each Glass Art Ai tumbler possesses its own visual character. Variations in the height and density of the white-to-blue transition, color blending, surface texture, glass flow, and overall contours are natural characteristics of individually hand-blown glass. These variations contribute to the individuality of each vessel and should not be considered manufacturing defects.
