Tughluq, the second king of the Tughlaq dynasty of India, and then his alchemical books were dedicated to the king. His first book, Miftāh al-romūz is an authentic book that deals with the fundamentals of Alchemy, covering 6 chapters and 31 parts. Two other Farsi books are left by him and unfortunately not well-known: Mighlād al-konūz which explains alchemical processes, tools and equipments used in alchemy and Muntakhab (a selection) of Miftāh al-romūz which is an independent treatise, however, more or less, is similar to Miftāh alromūz .
