A mosaic is defined as decorating of a surface with designs made up of closely set, variously colored, small pieces of material. Materials are stone, mineral, glass, tile, or shell. A mosaic is different from an inlay. With an inlay pieces are applied into a surface that has been hollowed out. When making a mosaic, pieces are applied to a surface that has been covered with an adhesive. An interesting fact about mosaics is that once taken apart, they cannot be put back together. Something else to know is that mosaics closely resemble wall paintings. The mosaics tended to copy the wall painting style. As mosaic artwork developed, it used stonger colors from different materials. This meant mosaics were more often used as covering on walls and vaults. Mosaics had finally reached the potential of this style, surpassing that of paintings.
