Pin Mont Fuji Verre à whisky

The polishing stage—the final step in production—restores the glass to transparency after cutting, revealing the characteristic luminosity and brilliance of Edo kiriko. Soda-lime glass, the most common substrate, undergoes this transformation, while high-class crystal receives additional chemical refinement through hydrofluoric acid treatment. The process employs a range of specialized discs: paulownia and willow wood, hair brush, and belt varieties, each suited to different sections of the piece. Water and polishing compounds are worked across the surface to achieve a glittering finish, with delicate areas refined by cloth or brush. A final buffing with cloth disc completes the work, drawing out the full radiance and depth characteristic of cut glass.
