Part 7 - Transformation of base metals into gold by haritala

First process.

Haritala is to be rubbed with the juice of rudanti. Copper leaf, smeared with this haritala, turns into fine gold.

Second process.

The leaf of a metal consisting of 16 parts of silver and 12 parts of copper is to be smeared with an amalgam made of haritala, makshika, hingula, manas-shila, and mercury, all rubbed together for three days with the juice of kakamachi, the weight of each of these metals being 3/2th (1½?) part of the leaf, which is to be heated after it is so smeared. The product is gold.

Third process.

Haritala with an equal quantity of manas-shila is to be rubbed with the juices of devadali and shiva-lingi for one day each. Five palas of powdered lead, tin, and mercury, each equal in quantity, are to be rubbed with the amalgam of haritala and manas-shila, described above, and with ghee and then subjected to puta. The process of rubbing with the amalgam and ghee and then of heating by puta is to be performed sixty times resulting in the preparation of a compound, which can transform 100 times its weight of tin into silver.
