Inlay covers a range of techniques in sculpture and the decorative arts for inserting pieces of contrasting, often colored materials into depressions in a base object to form ornament or pictures that normally are flush with the matrix.
Inlay is commonly used in the production of decorative furniture, where pieces of colored wood, precious metals or even diamonds are inserted into the surface of the carcass using various matrices including clear coats and varnishes.
Intarsia inlay in wood furniture differs from marquetry, a similar technique that largely replaced it in high-style European furniture during the 17th century,[2] in that marquetry is an assembly of veneers applied over the entire surface of an object, whereas inlay consists of small pieces inserted on the bed of cut spaces in the base material, of which most remains visible.
After learning the skill of smithing from the Navaho in 1872, the Zuni silversmiths cut small chips from crystals and gemstones, pearl shell and coral, to make inlay designs in a base of silver.
Angie Reano Owen, a Kewa Pueblo artist from New Mexico revived prehistoric Hohokam and Anasazi traditional designs in the 1970s with a new technique to inlay stone and shell mosaic jewelry.
