Part 5 - Mercurial operations (3): Rubbing of Mercury (mardana)

First process.

Mercury is to be rubbed (mardana) for three days separately with one-sixteenth its weight of soot, brick, white jira, burnt fur of ram, molasses, saindhava, (rock salt), each being mixed with a sufficient quantity of kanji.

Second process.

Mercury is to be rubbed for 3 days with each of the following:—Soot, brick powder, curd, molasses, saindhava (rock salt), and rajika (rye). The quantity of each of the things is to be one-sixteenth the weight of the mercury. When this is done, for the purpose of removal of dirt, the mercury is again to be rubbed with each of the following; abhra bhasma (mica reduced to ash), bija (purified gold or silver), and exhausted[1] mercury.

In course of being rubbed in this way, mercury assumes a clearer appearance at every rubbing.

N. B.—After each rubbing, mercury is to be washed, as previously stated, in an earthen vessel containing hot kanji.

Third process.

Mercury, in combination with a sufficient quantity of sour vegetable juice, is to be rubbed for three days with one sixteenth its weight of each of the following:—powdered brick, rock salt, molasses, rye, and soot.

Fourth process.

Mercury is to be rubbed constantly for one day or three days with the powder of each of the following, mixed with lime juice: red brick, haridra, dhumasara (soot), and urna (wool) reduced to ashes. The mercury is then to be subjected to upward sublimation for several times, or to be sifted by means of a thick piece of cloth; or to be washed off in kanji.

Footnotes and references:


In the absence of a better term we make it to mean???? Modern Chemistry has got nothing corresponding to???? (exhausted mercury),????. (dead mercury) and???? (mercury reduced to ash). Calomel and some other mercurial preparations may perhaps be considered to belong to the class of mur???? (swooned mercury).
