Part 3 - Incineration of tin

First process.

Leaves of tin are to be smeared with haritala and milk of aria and then subjected to Laghu-puta with the ashes of bodhi (called ‘bauri’ in Bengal) and chincha (tamarind).

Second process.

Melt some purified banga in an earthen pot placed over fire, and put upon it one sixteenth its weight of mercury. Then put a little purified haritala, every now and then, upon the compound which is to be frequently rubbed by means of a stick made of vanya karpasa wood, till the compound is reduced to ashes.

Third process.

Leaves of vanga are reduced to ashes, if they are subjected to puta after having been smeared with haritala rubbed with the juice of palasha.

Fourth process.

Vanga is reduced to ashes, if it is heated by fire made of chincha, palasha, and pippala wood, after having been mixed with oil or essence of bhallataka and wrapped with a piece of cloth.

Fifth process.

Vanga is incinerated, if subjected to puta for seven times after having been mixed with haritala and rubbed with milk of arka plant, dry barks of asvatha tree being placed on all sides of the vanga, while confined within the samputa.

Sixth process.

Purified leaves of vanga are to be melted in an earthen vessel, placed over fire, and an equal quantity of ashes of apamarga is to be mixed with the melted vanga. The whole thing is to be rubbed quickly by means of the chick end of an iron rod, till the whole thing turns into ashes, which are next to be freed from powdered charcoal, and again subjected to a very strong heat by puta. This results in the incineration of the vanga.

Seventh process.

Vanga is to be placed over fire in an earthen pot. When it melts, the following powders are to be placed upon it, the whole thing being turned constantly by means of an iron ladle:—turmeric, jamani, jira, chincha bark, and asvatha bark—all of these finely powdered. The whole thing is thus reduced to ashes. The ashes of the powders are then to be washed off by means of water, leaving the white powders of vanga deposited at the bottom.

Eighth process.

Vanga is incinerated, if it is subjected to heat by puta after having been smeared with a paste made of makshika, and haritala, duly rubbed with the juice of palasha leaves.

Ninth process.

Both vanga and sisaka(lead) may be purified in the same way, and both may be incinerated in the following way:—Ashes of asvatha and chincha and an equal quantity of haritala are to be rubbed with a sour-non-metallic juice or with the juice or decoction of palasha leaves. Vanga or sisaka is to be smeared with this paste and heated by puta. When cooled, the whole thing is to be taken out of the puta, rubbed again with one tenth its weight of haritala and the liquid referred to above, and then subjected to heat by puta, Twenty such putas are to reduce the vanga (or sisaka) into ashes.

Tenth process.

Leaves of vanga are to be smeared with one fourth their weight of mercury, and then with a paste made of bark of shirisha, turmeric, and juice of kanya. They are then to be put inside a paste made of rice and tamarind seeds, and then heated by puta. Twenty such putas result in the incineration of the vanga.

Eleventh process.

Tin melted in an earthen pot, kept over fire, is to be rubbed, by means of an iron ladle with salt petre, gradually put upon it, till fire comes out of it and burns the whole thing. Upon the fire being put out and the pot with its contents being cooled of itself, the ashes of tin are to be freed from those of saltpetre by means of water. The ashes, thus prepared, with an equal quantity of haritala, are to be rubbed with a sour vegetable juice, and subjected to heat by Gaja-puta. The product with one tenth its weight of haritala is again to be rubbed with a sour vegetable juice, and again subjected to heat by puta. Ten such acts of puta will kill the tin out-right.

Twelfth process.

Vanga is incinerated, if it is subjected to heat by puta, after having been smeared with a paste made of svarna-makshika, haritala, and juice of palasha.

Thirteenth process.

Leaves of vanga are incinerated by means of haritala, rock-salt, camphor, shells of crab, conch, oyster, and cowrie. [This may be effected in one of these two ways:—(1) Molten vanga may be roasted with the powder of the things specified, the ashes of which may be washed away afterwards, or (2) Leaves of vanga may be heated by puta after having been smeared with a paste of the things specified.]

Fourteenth process.

Vanga is incinerated, if it is heated by Gaja puta for forty times, after having been smeared each time with a paste made of bibhitaki and decoction of bhallataka and covered on all sides by means of sesamum cakes.
