Giyaman refers to traditional Japanese art glass, a term derived from the Dutch word diamant. During the Edo period, glass objects were rare and highly prized, later evolving in the modern era into an expressive art form closely associated with the aesthetics of the tea ceremony. Giyaman tea bowls are especially valued for their transparency, seasonal coolness, and interplay of light—qualities impossible to achieve in ceramics. ■ About the Artist: Mizusaki Chōju (水崎長寿) Mizusaki Chōju is a respected Japanese glass artist known for refined compositions that harmonize traditional tea aesthetics with contemporary glass techniques. His works are appreciated for their quiet elegance, technical precision, and sensitivity to light and movement, making them highly sought after by collectors of modern Japanese craft. ■ “Silver Foil Flow” (Ginpaku Seiryū) Design The Ginpaku Seiryū motif evokes a gently flowing stream rendered through embedded silver foil and soft, undulating glass lines. The silver leaf appears suspended within the glass layers, shimmering subtly as light passes through—an effect that recalls moonlight reflecting on moving water. This poetic visual depth elevates the piece from functional tea ware to sculptural art. ■ Aesthetic Appeal for the Tea Ceremony This glass tea bowl embodies a modern interpretation of wabi-sabi: quiet beauty, impermanence, and natural harmony. When used for matcha, the translucency enhances the vivid green of the tea, while the cool texture of glass makes it especially suitable for summer tea gatherings. It is equally compelling as a display object. ■ Period / Estimated Date Based on stylistic characteristics, materials, and the use of layered silver foil techniques, this work is estimated to date from the late Shōwa to early Heisei period (circa 1980s–1990s). Expert’s Insight: This piece represents a sophisticated convergence of traditional Japanese tea culture and advanced glass artistry. The controlled placement of silver foil within layered glass requires exceptional technical skill and precise temperature management during production. Works of this caliber—particularly those preserved with their original signed wooden box—are increasingly recognized in museum collections and serious private holdings of modern Japanese decorative arts. For European collectors, this tea bowl offers a rare opportunity to acquire a work that bridges Japanese tradition and contemporary design with undeniable visual impact.
