Who composed Rasaratnakara? [#2492]

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.
