c10.s5.5

Though brass has repeatedly been mentioned in alchemical works of the 13th century and later as an alloy, the proportions in which copper and zinc were mixed have not definitely been mentioned. From the Ayeen Akbari, however, we learn that during Moghul times brass was manufactured by melting two seers of copper and one and half seer of ruh-i-tutia or zinc.*
