In future, all archaeological excavations should be exhaustive - both vertically as well as horizontally - unearthing all possible material evidences. The artifacts as well as rejects, residues, wastes like slags etc. should be thoroughly examined by sophisticated techniques and equipments like electron microscope. It may be noted that many ancient Indian gems, minerals and metallic artifacts discovered in the 19th and early 20th century have not yet been subjected to phase studies; this is very important and should be done now. Identification of the ancient gems by the earlier mineralogists should be now corroborated by fresh X-ray and electron microscopic studies.
