In recent years, glass tiles have become popular for both field and
accent tiles. This trend can be attributed to recent technological
breakthroughs, as well as the tiles’ inherent properties, in particular
their potential to impart intense color and reflect light, and their imperviousness to water.
Glass tile introduces complexities to the installer. Since glass is more rigid than ceramic or porcelain tile, glass tiles break more readily under the duress of substrate shifts.
In the late 1990s, special glass tiles have been coated on the back side
with a receptive white coating. This has allowed impregnation of
heat-transfer dyes by a printing process reproducing high resolution
pictures and designs. Custom printed glass tile and glass tile murals
exhibit the toughness of glass on the wearing surface with photo-like
pictures. These are especially practical in kitchens and showers, where
cleanser and moisture resistance are important.
