The ancient Indian text "Rasaratnakara" (meaning "Ocean of Mercury" or "Jewel Mine of Mercury"), which delves into the intricacies of alchemy, metallurgy, and chemistry, is widely attributed to the Indian metallurgist and chemist Nagarjuna. This work is significant for detailing processes like the extraction of various metals including gold, silver, tin, and copper. While there can be some historical ambiguity due to multiple individuals bearing the name Nagarjuna and other texts with similar titles (like a 13th-century work by Nityanatha Siddha), the most prominent "Rasaratnakara" in the context of ancient Indian chemistry is associated with Nagarjuna, often placed around the 8th century AD.

Iron was not known to Indus Valley Civilization. The Indus Valley Civilization, also known as the Harappan civilization, was a Bronze Age civilization that lasted from 3300 BCE to 1300 BCE. The Indus Valley Civilization is one of three early civilizations of the Near East and South Asia, along with ancient Egypt and Mesopotamia. The Indus Valley Civilization's metallurgists used metals such as copper, lead, gold, bronze, and silver. The Indus Valley Civilization's inhabitants developed new techniques in metallurgy, including copper, bronze, lead, and tin.

Daojali Hading is a significant Neolithic site situated in the Dima Hasao District of Assam, India. It holds the distinction of being one of the first and most thoroughly excavated stratified Neolithic sites in North-East India. Archaeological findings from this site include characteristic polished stone tools (such as celts and adzes), as well as distinctive cord-marked pottery, grinding stones, and evidence of early metallurgical activities like iron slag. These discoveries provide crucial insights into the agricultural practices, tool technology, and early settled life of the Neolithic communities in the region, with artifacts dated around 2,700 years old.
