Travertine Tiles
Travertine is a sedimentary rock and a natural chemical precipitate of carbonate minerals; typically aragonite, but often recrystallized to or primarily calcite. Travertines are deposited from the water of mineral springs (especially hot springs) or streams saturated with calcium carbonate. When pure, travertine is white but often is brown to yellow due to impurities caused by the minerals it contains.
