Besides there are mentioned some other common rasas, such as, navasāra (salammoniac), hingula (cinnabar) (syn darada.), etc. 6

Gold (Kāñcana, suvaņra, pita or hema), silver (tāra of Raupya), copper (tāmra), lead (Śisā or nāga), tin (vaṁga) and iron (loha). It is interesting to note that there is mention of zinc (jasta)” in the Jaina MSS. on Alchemy.
