What is gold leaf made of?

Gold leaf is a type of thin sheet of pure gold that is commonly used in art, woodworking, and decoration. It is incredibly thin, with an average thickness of around 0.1 microns, making it delicate and easily manipulated. Gold leaf is typically made by hammering or rolling out a small piece of gold into an even thinner sheet and then sandwiching it between layers of other materials, such as paper or wax paper, to prevent it from tearing or sticking together. Gold leaf can range in color from a bright, shiny yellow to a more muted, aged look, depending on the manufacturing process used.
