According to the American
National Standards Institute (ANSI), porcelain tile is a type of
ceramic tile made by the pressed dust method. Ceramic tile is one
of the oldest building products known. Once available to only the
most affluent, through-body tile is considered one of the most fashionable
choices for floors, walls and countertops.
Through-body tile is derived from mixtures of clay, sand and other
natural minerals that are shaped into tile and fired at high temperatures.
The pressed dust method results in a porcelain tile with a density
so high that water absorption is less than 0.5%. Depending on project
objectives, porcelain tile may be purchased glazed, unglazed or
polished.
