The Heritage of Edo Kiriko (江戸切子)
The origins of Edo Kiriko date back to 1834 in the late Edo Period (modern-day Tokyo), when a glass merchant named Kagaya Kyubei began engraving intricate patterns onto glass surfaces using emery sand.
Over nearly two centuries, the craft evolved by blending traditional Japanese motifs with advanced European glass-cutting techniques introduced during the Meiji era. Recognized officially by the Japanese government as a National Traditional Craft, Edo Kiriko is celebrated worldwide for its breathtaking geometric precision, sharp refractive clarity, and fluid interplay of light. Unlike modern mass-produced glassware, every authentic piece carries the unique soul, rhythm, and patience of a master artisan's hands.
Meet the Maker: Master Craftsman
Every Celestial Planet crystal glass is brought to life in a specialized workshop by a dedicated master artisan. In the world of traditional Japanese glasswork, it takes a minimum of 十载 (ten years) of rigorous training just to be recognized as an independent craftsman.
Our master artisan guides the raw crystal through a grueling multi-stage journey:
- Waridashi (Guidelines): Hand-marking precision horizontal and vertical axes directly onto the curved, crystal-clear surface.
- Arazuri (Rough Cutting): Using a coarse diamond wheel to slice into the heavy base and walls, forging the initial paths for the sweeping orbital lines and planetary depressions.
- Sanbankake (Refined Engraving): Painstakingly tracing the microscopic lines of the intricate celestial starbursts and cosmic geometric rings with fine abrasive wheels.
- Migaki & Bafugake (The 1,500-Step Polish): Utilizing traditional wooden wheels and soft cotton buffing cloths with rare polishing minerals to smooth every cut surface, unlocking a dazzling, diamond-like luster.
"There is no machine in the world that can duplicate the judgment of a craftsman's eye and the delicate pressure of their hands against the wheel. A single millimeter off, and the entire glass must be discarded." — Master Artisan
