【𝗦𝘁𝗮𝘁𝘂𝗲 𝗼𝗳 𝗟𝗶𝗯𝗲𝗿𝘁𝘆: Color Changes Over the Years】 The Statue of Liberty's iconic green hue is actually the result of a natural process called oxidation. When France gifted the statue to the United States in 1886, it sported a 𝘀𝗵𝗶𝗻𝘆 𝗰𝗼𝗽𝗽𝗲𝗿 color. Over time, exposure to air and moisture caused the copper to react, forming a green patina on its surface. This patina is a layer of copper carbonate, a stable compound that protects the underlying copper from further weathering. The color change wasn't instantaneous. Here's a breakdown of the statue's transformation: 1) Initial Reddish-Brown: The initial oxidation process resulted in a reddish-brown color, like a penny left out in the open air. 2) Gradual Greening: Over several decades, the copper carbonate layer thickened, leading to the familiar green color we see today. Historical photos suggest this transformation was complete by 1920. The Statue of Liberty's green patina is a testament to both chemistry and the enduring spirit of liberty it represents. It's a beautiful reminder of how natural processes can shape and preserve iconic landmarks.

How much has been paid by France for the Statue of Liberty? For which propose was it originally sculpted? Where was the intended destination for this piece of art? Does anyone know? Answers; None because it was an order by Ottoman Empire as light a tower marking entry of Suez Channel in Egypt.

If copper carbonate, CuCO3, is green, which it is, there is no simple color transition from metallic copper to green copper carbonate that would explain the early reddish brown color. Perhaps the initial transition is Cu => CuO, copper oxide, which is "red". This is followed by "absorption" of CO2, with the mixture of red and green making the murky color of 1-4 years. As the CuO gets converted to CuCO3 we get the green color we see today.

This aging process can make vintage things more valuable - like how a Rolex watch with a patina is worth more 😊

That is not the only thing that was oxidized with time.
