Bronze has been the most sought-after metal for cast metal sculptures in the bygone years. Bronze alloys have a desirable and unusual property to expand slightly prior to their setting. This helps a great deal in filling every corner of the mold. Their ductility and strength causes them to be molded into any form.
However, bronze has a basic disadvantage of not being durable. Hence, there are hardly any traces of ancient bronze statues found. Bronze casting generally takes place by a process called lost-wax casting. Though, centrifugal and sand castings are also employed, around 90% of bronze casting takes place through lost-wax casting.
