Synopsis A Sequel to his widely acclaimed Minerals and Metals in Ancient India, in two volumes, (1996), Professor Biswas here continues with the fascinating story of indigenous gems, non-gem minerals, metals and metallic art : from 1200 AD onwards to almost the threshold of modern times Beginning with a view of medieval India's enchanting gems, its highly dexterous diamond mining, and an array of non-gem minerals including, among others, metallic ores of copper, lead, zinc, ferrocobaltite, aluminium, and even building stones, the book offers a focused study of iron and steel, brass and zinc in pre-modern India -- with coherent descriptions of the diversities of ores processed, smelting techniques, wootzmaking and other products in different parts of the subcontinent. A painstakingly researched work based on foreigners' travelogues and many other sources, the book re-explores the achievements of indigenous industries of the day, highlighting how, for about two millennia since the Lothal and Atranjikhera eras, India commanded primacy in zinc and brass; how its zinc smelting and distillation technology were transferred to the West, like the Chinese technologies of paper and gunpowder; and how its artisans could work marvels in metal. The author examines, in retrospect, Indian traditions of metallic works, which are vividly exemplified in its arts of enamelling, encrustation, jewel-setting, brass and high zinc Bidriware, and much else.
