What is the Liberty Bell made of?
A metallurgical analysis of the Liberty Bell shows the composition to be approximately 70% copper, 25% tin, 2% lead, 1% zinc, .25% arsenic and .20% silver with trace amounts of gold, magnesium, nickel and antimony. The elements are found in differing ratios throughout the Liberty Bell suggesting that the casters, Pass and Stow, did not have a large enough furnace to melt down all the pieces of the Bell at one time during recasting, but used small crucibles to complete the project.
