iroiri

iroiri refers to a decorative technique in Japanese lacquerware, known as urushi. It involves the inlaid application of thin pieces of metal, often gold or silver, into carved grooves or designs on the lacquered surface. The term itself translates roughly to "color entering" or "color inlaid," reflecting the process of filling recesses with colored materials. While gold and silver are most common, other metals and even mother-of-pearl or shell can be incorporated.

The technique is characterized by the contrast between the metallic inlay and the dark, often lustrous, lacquered background. This creates a visually striking and elegant effect. The application requires considerable skill and precision, as the metal leaf or powder must be carefully pressed into the prepared grooves before the lacquer fully hardens. Once set, the surface is often polished to a smooth finish, making the inlay appear to be an integral part of the lacquer itself. iroiri is found on a variety of objects, including boxes, trays, and decorative panels, and has a long history in Japanese art.
