Question

describe the lost wax process of solid and hollow casting​

Answer 1

Lost-wax casting is the process by which a duplicate metal sculpture (often silver, gold, brass or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.The oldest known example of this technique is a 6,000-year old amulet from the Indus Valley Civilization.

Hollow casting is a method of pouring liquid clay into an empty plaster mold for producing a shell of a particular shape. The method differs according to the medium used. Mostly, cast metal sculptures are designed in a hollow manner to confirm that none of its parts are thicker than the other.
