Do you know the value of bronze statues?
Bronze was first used to cast practical objects such as cannons and mortars, but in the 15th century, it was increasingly used to cast statues and sculptures. Thus Florence witnessed the first real flowering of bronze sculpture.
Bronze is an alloy of copper and tin (in contrast to brass, which is an alloy of copper and zinc). A small amount of other elements can also be added in order to increase the fluidity of the liquid. The typical modern bronze is 88% copper and 12% tin.
