(Also see Mixed-Material Mosaics)
Mosaic tiles can be made of glass, delicate glass, porcelain, ceramic, polished stone or honed stone as well as a variety of other natural and man-made materials.
Mosaic tiles are very small or tiny tiles – usually about 1″ x 1″ in size. They can be sold individually for artistic applications, but they are more typically sold in sheets where each small tile is adhered to a mesh backing. The actual size of the tile refers to the average size of each individual tile – not the size of the sheet. When setting the mosaic sheets, leave a space between each sheet that matches the width of the space between the individual mosaic tiles. This will help to achieve a clean, uniform look.
