Siena Marble is a type of marble that is quarried in the Tuscany region of Italy, near the city of Siena. It is a type of metamorphic rock that is formed from limestone that has been subjected to intense heat and pressure.
Siena Marble is known for its distinctive reddish-brown colour, which comes from the presence of iron oxide minerals in the rock. It often has a mottled or veined appearance, with lighter and darker areas of colour.
This type of marble has been used in sculpture and architecture for centuries. It was a popular building material during the Renaissance, and can be found in many historic buildings in Italy, such as the Siena Cathedral and the Florence Cathedral. It has also been used in a variety of decorative applications, such as flooring, cabinet tops, and fireplace surrounds.
Siena Marble is highly valued for its beauty and durability and is still quarried today. However, due to its limited availability and high cost, it is primarily used in high-end luxury projects. It is worth noting that the quality of the Siena marble exploited in the 18th century is now depleted. The marble that is now extracted has a lighter, less robust colouration.
