Coagulatio

Coagulation. To catch what flees. The Great Work is a war against the volatile — against what evaporates, rises, and is lost in air the moment fire touches it. Coagulation is the operation that arrests that escape. It fixes what is slippery. It gives body to what had none. It turns vapor into stone and spirit into flesh. It is the work of earth: solidifying, anchoring, the descent of the celestial into the concrete. In the center of the matraz — the glass egg wherein the whole Work unfolds — a small green dragon, crowned, spits a red flame. That dragon is the wild force of matter, the volatile and burning principle that resists fixation, the beast the alchemist must imprison and tame within the sealed vessel. Crowned, because it is king of its own nature. Green, because it still holds the raw power of the first matter. Spitting fire, because it burns yet with the energy that will not be extinguished. Beneath, the red liquor filling half the vessel is the matter already worked — the firm and stable ground upon which the dragon must at last alight. The image holds the exact pulse of coagulation: the struggle between what would escape and what compels it to remain. To coagulate is to bring the force that burned and fled into body at last. Every idea, every dream, begins as a volatile dragon that burns in the mind and threatens to vanish into air. It becomes real only when someone seals it, works it with patience, and compels it to take form. Nothing fully exists until it coagulates — until it descends from air and becomes earth.

Coagulatio involves a cooling, combining and condensing of what has been previously dissolved so that through this fixation, a new homogeneous whole is formed. The operation is in contrast to destillatio, sublimatio and solutio, in which the lower fixed material is refined, purified and transferred to the airiness of the spirit or the liquid form of the water, for here, a reverse fixation and coagulation of the spirit occurs. The soul-spirit is again given a body in which to reside, like a deity in an earthly temple. Broadly speaking, it is the two operations that dissolve and join – solve & coagula – around which the entire opus magnum revolves. Through coagulatio, the queen and king, mercury and sulphur, or the astral and the etheric bodies are united into a single body of salt. In herbal alchemy, this means that the herb’s mercurial spirit and sulphurous soul are reunited with the body of salt, and the spagyric elixir is then completed. From a psychological point of view, the process often means that something crystallises and finds new clarity in order to be realised and manifested in life. In the great work, the work of a coagulatio is perfected when the golden and solar consciousness finally receives physicality and forever endures in the alchemically deified human being.

Understand this concerning Coagulation which is done after purification, which purification hath nothing else to be done but in the putrefaction and conversion of the body into a mere spirit, and when thou shalt have this, Praise God. ~ Ibn Geber - Abu Mūsā Jābir ibn Hayyān - جابر بن حیان‎, - جابر بن حیان‬‎ 721-815.AD.
