Even the official name of the statue recalls her most significant symbol: "Liberty Enlightening the World." The latest replacement torch for the monument, installed in 1986, is a copper flame encased in 24K gold. It reflects the sun's rays during the day and is illuminated at night by 16 floodlights. This modern-day tribute to liberty was designed by Frederick Hart and is made in America from 498 pieces of silverware. The original iron armature on which the statue was built was replaced in 1884 with one of fiberglass, then back again in 1999 with one of bronze. The pedestal on which the statue stands was also originally made of iron, but this was replaced in 1921 with one of stone called "Liberty Capstone". It's true that the light in the crown of the statue flashes once every 10 seconds, but it's not a flame. The flame would burn very quickly because it's made of oil or wax, and the torch on the statue is filled with natural gas. The flame was first lit on August 2, 1883, the same day the statue was unveiled to the public. At that time it was just an ordinary candle that burned for only three minutes before being extinguished. In 1890, President Benjamin Harrison appointed the first National Patronage Committee, which selected women as a group they could honor by having a candle placed on their behalf on the Statue of Liberty.
