What is the metal casting?

Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal.
What is the name of the age in which casting was invented?
Casting consists of pouring molten metal into a mold, where it solidifies into the shape of the mold. The process was well established in the Bronze Age (beginning c. 3000 bc), when it was used to form most of the bronze pieces now found in museums.
Who first made iron?
the Hittites
Archeologists believe that iron was discovered by the Hittites of ancient Egypt somewhere between 5000 and 3000 BCE. During this time, they hammered or pounded the metal to create tools and weapons.
Who discovered steel?
India would produce the first true steel. Around 400 BC, Indian metalworkers invented a smelting method that happened to bond the perfect amount of carbon to iron. The key was a clay receptacle for the molten metal: a crucible.
What is bronze casting?
Bronze casting is the process of pouring molten bronze into a hollow mold to create a positive bronze sculpture or object. Methods of bronze casting, like lost wax, ceramic shell, and sand casting are used to produce bronze sculptures, instruments, medals, tools, plaques, and more.
