The opus alchymicum consists of a repeated series of dissolutions and coagulations - the dissolution of the old metal or matter of the Stone into the prima materia and the coagulation of that pure materia into a new and more beautiful form.
Abraham establishes coagulation as the essential complementary pole to dissolution within the iterative alchemical opus, whereby each cycle of solve et coagula produces progressively purer and more potent matter.
