The tile industry has recently made a strong presence in the use of Dichroic Glass. Some problems have been associated with the variance of colors. Large tile manufacturers that require a large lot of the same exact color have difficulties, since the coatings vary in color slightly, from one sheet to another. Nevertheless, accent tiles, mosaics, patterns, and abstract tiles are very popular and are even currently being sold in large home and garden stores such as Home Depot Expo.
