Yet some were composed out of other materials, such as bronze. Interesting enough, the ancient Greeks were actually known for their statuary in bronze. Bronze, which is 90% copper and 10% tin, has a lower melting point than pure copper and will stay liquid longer, allowing the artists to mold it at more ease. Copper came from Greece but tin had to be imported from other places, such as Turkey. Most bronze statues were melted down to reuse for other functions but marble copies were made in their place. This is why we have more marble statues than bronze statues.
