The Statue of Liberty is made of copper 3/32 in. (2.4 millimeters) thick, the same as two U.S. pennies put together. Why is the Statue green? The Statue's copper has naturally oxidized to form its familiar "patina" green coating.
The Statue of Liberty's exterior is made of copper, and it turned that shade of green because of oxidation. Copper is a noble metal, which means that it does not react readily with other substances. The Statue's copper is only three-thirty-seconds of an inch thick and unusually pure.
The copper fastenings ensure structural integrity and, as part of the total materials system, guard against any galvanic reaction problems.
The statue of liberty was made of copper. Copper is extremely weather-resistant. It will gradually oxidize copper chloride, which is greenish in...
Copper naturally turns green over time as it reacts with oxygen in the air – a chemical reaction known as oxidation.
Copper goes green and turquoise after prolonged exposure to moisture. Without accelerating the process, it can actually take 20 years or more in dry climates for this patina to develop.
Copper is essential for good health. However, exposure to higher doses can be harmful. Long- term exposure to copper dust can irritate your nose, mouth, and eyes, and cause headaches, dizziness, nausea, and diarrhea.
Copper can be absorbed into the systemic circulation from the gastrointestinal tract, the lungs, and skin (U.S. EPA, 1987).
Copper is a mineral that you need to stay healthy. Your body uses copper to carry out many important functions, including making energy, connective tissues, and blood vessels. Copper also helps maintain the nervous and immune systems, and activates genes. Your body also needs copper for brain development.
Copper in its metallic state has no effect on the skin and it becomes a potential irritant or allergen when it is corroded to become soluble through the action of exudates encountered on the skin surface, or in a relatively corrosive physiological environment such as the oral cavity or the uterus.
Copper melts at almost 2000 degrees F. A bonfire will get to about 1100 degrees F. To get to a temperature that will melt copper, you have to increase the rate of combustion.
Copper has two key properties that endow it as an excellent active ingredient to be used in products, which come in contact with the skin, aiming to improve the skin's well-being. Copper plays a key role in the synthesis and stabilization of skin proteins, and it also has potent biocidal properties.
Copper has shown to have strong antimicrobial properties, with the ability to kill various bacteria including MRSA. It has also been shown that copper promotes new blood vessel formation and therefore enhance wound healing.
Oysters and other shellfish, whole grains, beans, nuts, potatoes, and organ meats (kidneys, liver) are good sources of copper. Dark leafy greens, dried fruits such as prunes, cocoa, black pepper, and yeast are also sources of copper in the diet.
Egg is rich in phosphorus, calcium, potassium, and contains moderate amounts of sodium (142 mg per 100 g of whole egg) (Table 3). It also contains all essential trace elements including copper, iron, magnesium, manganese, selenium, and zinc (Table 3), with egg yolk being the major contributor to iron and zinc supply.

Signs of possible copper deficiency include anemia, low body temperature, bone fractures and osteoporosis, low white blood cell count, irregular heartbeat, loss of pigment from the skin, and thyroid problems.
