Panchaloga

From Wikipedia, the free encyclopedia

Panchaloha (also called Panchaloham or Panchaloha - literally, five metals) is a term for traditional five-metal alloys of sacred significance used for making Hindu temple icons (Murti).

The composition is laid down in the Silpasastra, an ancient Sanskrit text on icon making. It is traditionally described as an alloy of gold, silver, copper, brass and iron, but copper is the major constituent, making Panchaloga generically a cast brass or bronze.

Practical compositions are Cu, Au, Ag, Pb and Zn; Cu, Ag, Pb, Fe and Sn; and Sn, Cu, Fe, Pb, and brass. Because of the cost, Au and Ag are now omitted from general-purpose icons, where copper, brass, and lead in the ratio 29:2:1 are used.
