veneer

   The thin slice of a material — often of a rare and expensive material — applied, generally with an adhesive, but also (and sometimes only) with pins, to a surface of a humbler material. Ebony, rosewood, tulipwood and other exotic woods are more often used as veneers in furniture-making than they are used in a solid form. Most wood veneer is sliced rather than sawn, and taken from a log in a continuously spiraling (voluting) cut, and then flattened. Because of concern that such veneer may be more likely to curl away from its placement, some feel that flatly sawn veneer is preferable. Sawn veneer however, because the saw destroys as much wood as the veneer it produces, is much more expensive. Brass, copper, ivory, mother-of-pearl, pewter, and tortoiseshell can also be used and are often combined with such woods. Semi-precious stones such as lapis lazuli and malachite (also used for inlay) are sometimes employed as a veneer, as are the more showy types of calcite alabaster. Veneering is more easily achieved on a flat surface, but thin slices of wood can be bent, for example into the hollow of a molding. Stone cannot be bent, so its veneering on curved or complex forms is particularly difficult. There are plastic sheet materials also called veneers, many simulating other materials, such as bricks, stone, lap siding, shingles, etc. Also see basket, cladding, intarsia, laminate, marquetry, mosaic, and parquetry.
