copper, iron, silver, and gold; now roast them in a closed crucible, &c.[1]

[Here as well as in the preceding sloka, we have distinct mention of अन्धमूषा or a crucible with the lid on. This is one of the preparations which can be brought into line with those of the Tāntric and Iatro-chemical periods.]
Preparation of Alkali and Caustic Alkali[3]
[As Vāgbhata borrows his method of preparation of alkali almost word for word from Susruta, it is quite superfluous to reproduce it here.]
