What makes the status of liberty look green?

The Statue of Liberty is not actually green. It is made of copper, which naturally tarnishes to a greenish-brown color due to exposure to the elements. The process of oxidation, or the reaction of copper with oxygen, creates a layer of copper carbonate on the surface of the statue. This copper carbonate layer is what gives the statue its green appearance.

The Statue of Liberty was originally a bright copper color when it was first constructed in the late 19th century. However, the statue quickly began to tarnish due to its exposure to the harsh Atlantic Ocean environment. By the early 20th century, the statue had turned almost completely green.

In 1906, the statue was treated with a chemical solution to slow down the tarnishing process. This treatment was effective, and the statue has remained largely unchanged in color since then.

The green color of the Statue of Liberty has become an iconic part of the statue's identity. It is a symbol of the statue's age and history, and it is also a reminder of the natural forces that shape our world.
