Physical properties
Hardness: 3-4 (Mohs scale), Color: Cream, tan, and beige with light pitting, Luster: Dull to matte (honed), Crystal Structure: Trigonal, Specific Gravity: 2.4 - 2.7
Formation & geological history
Formed by the rapid precipitation of calcium carbonate from mineral springs, typically hot springs. Over geological time, these deposits compact into layers of stone. The tiles pictured are likely manufactured from quarries in Italy or Turkey.
Uses & applications
Extensively used in construction for flooring, wall cladding, and bathroom tiles due to its thermal efficiency and aesthetic appeal.
Geological facts
Travertine was used to build the exterior of the Roman Colosseum. It is unique for its natural voids caused by trapped gas bubbles during the deposition process.
Field identification & locations
Identified in the field by its porous texture and concentric/fibrous appearance. Common in limestone-rich areas near volcanic activity. Used by collectors as a decorative building stone.
