Solve et coagula — dissolve and coagulate — stands as the axial dictum of operative alchemy and, by extension, of its depth-psychological appropriation. Within the corpus, the term functions simultaneously as a technical description of alchemical procedure, a structural metaphor for psychic transformation, and a philosophical principle governing the rhythm of dissolution and reconstitution that underlies individuation. Abraham's lexicographic treatment establishes the procedural foundation: the repeated cycling of solid into fluid and fluid back into solid purifies and potentiates the matter of the Stone, making the opus alchymicum an iterative rather than linear movement. Hillman radicalizes this into a hermeneutic of psychological change, reading solve et coagula as the engine behind the nigredo's deconstruction of fixed identities and the ground of all genuine psychic movement. He also tracks the phrase into unexpected cultural terrain, noting how the rubedo exteriorized historically in revolutionary politics. Moore's Ficinian index situates the term alongside solutio and sublimation as a linked cluster within Renaissance astrological psychology. Jung's autobiographical testimony in Memories, Dreams, Reflections records his first encounter with the phrase as a key node in his attempt to decode alchemical language through philological accumulation — a moment of recognition that was foundational for analytical psychology's claim upon alchemical symbolism. The corpus reveals a productive tension between Abraham's historically grounded lexicography and the more freely interpretive deployments by Hillman and the Jungian tradition.
With each cycle of solve et coagula the matter in the alembic becomes purer and more potent.
Abraham defines solve et coagula as a repeated iterative process of dissolution and reconstitution by which the alchemical matter is progressively refined and empowered.

Black is itself not a paradigm, but a paradigm breaker. That is why it is placed as a phase within a process of colors, and why it appears again and again, in life and in work, in order to deconstruct (solve et coagula) what has become an identity.
Hillman uses solve et coagula parenthetically to gloss the nigredo's function as a repeated deconstructor of fixed psychological identities rather than a stable endpoint.

authority derives from the underlying alchemical principles of solve et coagula: what is fluid must be solidified and what is solidified
Hillman invokes solve et coagula as the foundational alchemical principle undergirding Michelangelo's Moses, construing the figure's terribilità as an embodiment of the dual movement between fluidity and fixity.

Reading the sixteenth-century text, 'Rosarium Philosophorum,' I noticed that certain strange expressions and turns of phrase were frequently repeated. For example, 'solve et coagula,' 'unum vas,' 'lapis,' 'prima materia,' 'Mercurius,' etc.
Jung records solve et coagula as among the key recurring phrases that first signaled the systematic symbolism of alchemy and prompted his philological method of building a concordance of alchemical language.

The operation of purifying and refining the matter is accomplished through the 'solve et coagula process known as 'cooking, and through the 'ablution or washing
Abraham situates solve et coagula as the overarching procedural framework within which more specific operations — cooking, washing — serve as its concrete instantiations.

The Sophie Hydrolith says that the dissolution of this matter in the cycle of 'solve et coagula occurs 'by mean
Abraham cites the Sophie Hydrolith to show that classical alchemical authorities framed the dissolution of prima materia explicitly within the cyclical structure of solve et coagula.

Moore's index places solve et coagula in direct proximity to solutio and sublimation, indicating its structural role within his Ficinian astrological psychology as part of a cluster of transformative operations.

Solutio: alchemical, 67–69; poetic, 100 Solve et coagula, 66, 70,
The earlier edition of Moore's index identically situates solve et coagula alongside solutio and sublimation, confirming the conceptual cluster's stability across revisions of his Ficinian framework.

Of all the terms, I must mention especially one pair of operations that have come to
Hillman signals that among all alchemical operational pairs, one dyadic term holds special psychological significance — a passage that contextually introduces the solve et coagula pairing as uniquely central to the craft of psychic work.
