Meaning
Charcoal is a stage in the descent from volatile spirit through acid and oil toward salt, ash, and glass. The author calls it coagulated oil and, conversely, describes oil as charcoal resolved into liquid. This is a theory of material continuity under different degrees, not a modern statement that all oils and charcoals have one composition (B2C05S059).
It is often the dead head left after an animal or vegetable subject has yielded volatile, acidic, and oily portions. Yet caput mortuum does not mean that it is devoid of all power. The book sharply distinguishes the fact that a portion remains at the bottom from the judgement that it is worthless. The residue may hold the more fixed sulphur and tincture that the operation needs (B1C20S002–003; B2C05S057–058).
Use in the book
The defence of charcoal is a major attack on careless purification. Practitioners who burn it entirely to ash and discard further residues can remove the very body required for lasting fixation. The author argues that fixed diseases, within his historical medical scheme, require an appropriately fixed medicine, making rejection of charcoal one cause of failure. These therapeutic assertions explain his polemic; they are not recommendations to administer charcoal preparations (B2C05S057).
He then answers the objection that no solvent attacks charcoal. The ordered relation of its own parts supplies an explanation: oil is its neighbouring degree, acid a further middle, and volatile spirit the still subtler portion. Returning a body through what it formerly was is more important than applying a famous foreign solvent. The account also says that equal or insufficiently opposed portions may produce a third condition rather than one conquering the other, so the rule involves degree and predominance as well as affinity (B2C05S059–061).
Charcoal’s colouring power supplies a second defence. Salt of tartar can take a tincture from charcoal or flame-borne sulphur, leading practitioners to attribute that colour to the salt itself or even to a solar substance caught from the air. The author instead follows the material that entered the operation. Charcoal also leads beyond itself: open calcination gives ash and salt, and their combination can become glass. The darkest apparently spent matter thus stands within the same chain as a translucent, durable body (B2C05S062–070).

Translation in this edition
Kohlen can denote furnace coals as well as a subject’s charcoal residue; context must distinguish fuel from analyzed body. The Latin carbones appears in the technical classification. Caput mortuum, rendered “dead head,” is an operative residue-name that the author refuses to treat as a proof of lifelessness. Nor is every dead head identical: animal, vegetable, and mineral subjects leave different fixed parts with their own specified relations (B1C18S001; B2C05S057–059).
