Part 4 - Lavana (4): Sauvarchala or Sauvarcala (salt-petre)

It is the same as ushara-kshara or salt-petre. It is both an alkali and a salt. Eor the preparation of salt-petre, see page 268.

Preparation of artificial sauvarchala.

An equal quantity of powdered svarji (natron) and saindhava (rock-salt) are to be mixed together and dissolved with water in an earthen vessel which is to be heated strongly till the solution melts well and then dried up. The heat is to be continued for some time after the drying up of the product.

The product may be used as sauvarchala salt, and not as sauvarchala-kshara.

(N.B.—The salt, thus prepared, may be used in lieu of salt-petre, where the emphasis is laid on the word ‘salt’, but where there is a stress on the word “kshara”, only salt-petre, and not its substitute, should be used.)
