Mosaic work is a type of art that involves the use of small pieces of material such as stone, glass, ceramic, or wood to create a larger image. INLAY is a form of mosaic work in which pieces of material are cut to fit into a pre-cut surface, while intarsia is a form of mosaic work in which pieces of material are cut and fitted together without the use of a pre-cut surface. Both techniques are used to create intricate designs and patterns.
