The data, collected from chemical, spectrographic, metallographic and archaeological analysis of the selected antiquities, and interpreted in technological terms, indicate the advanced state of ancient Indian Technology and reveal the stupendous intellectual efforts made by the Early. Indians in exploiting the natural mineral resources and making of a variety of materials-ceramics, glasses and metals, including copper, silver, gold, iron and their alloys.
The study reveals the awareness of ancient Indians to the proper formulation and selection of raw materials as well as to the understanding of colour Chemistry in making silicates and glasses. The work also throws new light on the controversial nature of the slip (coating) on the deluxe N.B.P. ware and on the metallurgical achievements of ancient Indians.
