The opus, the work [Dorn says], consists of two basic steps: first comes the solution, the dissolution of the body; and second the coagulation or condensation of the spirit [by which we can guess he means the opening of the body to the heavenly influence by melting or evaporating it and destroying what we would call the coarse outer appearance] after which the hidden gold appears which has to be coagulated into a new body, and that would be the gold.  As you remember, gold is the form separated from the body.  These three simple operations are like making the quintessence of wine.  AAI 45
