Travertine is a product of chemical
reactions, a geological chemical inorganic precipitated
limestone formed by the evaporation of supersaturated calcium carbonate rich waters,
generally in hot springs. It is predominated by a cavity structure up to 1/2 in size.
These
cavities are frequently filled with matching or a contrasting colored cement or epoxy.
Commercially Travertine has been placed
into the classification of the trade
term
"Marble", because it can take a reflective polish, however,
due to its peculiar
characteristics (its cavity structure) it is generally considered apart from marble
and limestone.
