The Investment casting technology, also known as lost wax process is no stranger to the Indian sub-continent. The art was vastly practiced in ancient India for casting Idols and art objects mostly in copper alloys. The lost-wax method is well -documented in ancient Indian literary sources. The Silpasastras, a text from the Gupta Period, contains detailed information about casting images in metal. The fifth-century AD Vishnusamhita, an appendix to the Vishnu Purana, refers directly to the modeling of wax for making metal objects in chapter XIV: "if an image is to be made of metal, it must first be made of wax." [Chapter 68 of the ancient Sanskrit] text Mānasāra Silpa details casting idols in wax and is entitled "Maduchchhista vidhānam", or "lost wax method".
The Manasollasa (also known as the Abhilasitartha chintamani) was allegedly written by King Bhulokamalla Somesvara of the Chalukya dynasty of Kalyani in AD 1124-1125, and also provides detail about lost-wax and other casting processes. In a 16th-century treatise, the Uttarabhaga of the Silparatna written by Srikumara, verses 32 to 52 of Chapter 2 ("Linga lakshanam") give detailed instructions on making a hollow casting.
Metalcasting began in India around 3500 BC in the Mohenjodaro area, which produced earliest known lost-wax casting, the Indian bronze figurine named the "dancing girl" that dates back nearly 5,000 years to the Harappan period.
Producing images by the lost-wax process reached its peak during from 750 AD to 1100 AD, and still remained prevalent in south India between 1500 AD and 1850. The technique still remains well practiced throughout India, as well as neighbouring countries Nepal, Tibet, Ceylon, Burma and Siam. During the second world war, the process was upgraded for industrilisation.
