Travertine
What is Travertine?
Travertine is a form of limestone deposited by mineral springs, especially hot springs. It is characterized by its porous texture, which is a result of the escape of carbon dioxide. Travertine is often used in building and construction due to its durability and aesthetic appeal. The stone's appearance can vary widely, with colors ranging from light beige to reddish-brown, depending on the mineral content.
