Statue of Liberty
Design and construction process
After consultations with the metalwork foundry Gaget, Gauthier & Co., Viollet-le-Duc chose the metal which would be used for the skin, copper sheets, and the method used to shape it, repoussé, in which the sheets were heated and then struck with wooden hammers. An advantage of this choice was that the entire statue would be light for its volume, as the copper need be only 0.094 inches (2.4 mm) thick. Bartholdi had decided on a height of just over 151 feet (46 m) for the statue, double that of Italy's Sancarlone and the German statue of Arminius, both made with the same method.
