It is named after Tivoli, Italy ("Tibur" in Latin), where large deposits occur, and it is characterized by a light color and the ability to take a good polish. It is typically banded, due to the presence of iron compounds or other organic impurities. It is often used for walls and interior decorations in public buildings. It is distinguished from "tufa" by being harder and stronger. ]]></note></mads>
