Hirota Glass applies Edo Kiriko techniques to a glass clock, offering a new way to appreciate its craftsmanship beyond traditional drinkware. The clock’s circular glass face is cut at twelve points corresponding to the hours, linked by 48 total cuts. These intersecting lines form a geometric design reminiscent of kiku (chrysanthemum) blossoms, a classic design in Japanese culture.
Unlike most wall clocks, this clock features transparent glass, allowing the interplay of light and shadow to project onto the wall behind. As daylight shifts over time, the intricate cuts create continuously changing highlights and shades, making the passage of time itself a captivating experience. Its understated aesthetic enables it to blend effortlessly into various interior styles.
Developed from a fresh perspective by a historic Tokyo-based glassware manufacturer, this product aims to further promote Edo Kiriko—a traditional craft of Tokyo.
