Khatam means "incrustation". This craft consists in the production of incrustation pattern (generally star-shaped, with thin sticks of wood (ebony, teak, ziziphus, orange, rose), brass (for golden parts), camel bones (white parts). Ivory, gold or silver can also be used for collection objects. Sticks are assembled in triangular beams, assembled and glued in a strict order to create a cylinder, whose cross-section is a six-branch star included in a hexagon. These cylinders are cut shorter, compressed and dried between two wooden plates.
