CONVERT — To Convert the Elements. This expression of Hermetic Chemistry signifies to Dissolve and to Coagulate to change body into spirit and spirit into body to volatilize that which is fixed, and to fix that which is volatile. All these terms refer to one only operation, which Nature, assisted by art, performs in one vessel, which is the Vase of the Philosophers, by the same process continuously persisted in, when the matter has been thoroughly purified and sealed in the Hermetic Egg. It is then simply a question of the conduct of fire.
