Meaning

The salt-of-metals dictum is accepted only under a regenerative interpretation. Khunrath does not deny that salt-like preparations can be made from silver or gold. He denies that producing them by ordinary metallic manipulation fulfils the saying that the salt of metals is the Philosophers’ Stone.

Use in the book

Page 125 announces the problem in both body and margin. Workers read the saying as an authorization to transform the metals into coloured salt-crystals through prolonged preparation. Khunrath grants such products medicinal standing, but that concession does not grant them transmuting power.

The next page distinguishes salt-products associated with corrosive additions. Their sharpness and their staining of wood or skin are not the claimed tinctorial effect upon lower metals. The argument therefore concerns more than whether a substance looks crystalline or dissolves: origin, preparation and the kind of action attributed to it remain decisive.

Page 127 then gives the positive condition. The salt of metals is suited to the philosophical purpose when regenerated and more-than-perfected through the pri-material twofold catholic Mercury. The purest of the whole metallic mass, rather than an isolated salt-fraction treated as self-sufficient, belongs in the account. The proposed result is described as fixed, smokeless and wax-flowing, sapphirine for silver and rubine for gold.

This separates metallic salt as an extracted essential part from the name applied to a regenerated metallic whole. Without that distinction, the same word appears to license the very self-contained metal process the preceding objection has rejected.

Places to read

  1. 1599 p. 116Khunrath grants that a salt can be obtained from a metal.
  2. 1599 p. 120Silver-ness and gold-ness belong throughout the essential parts of the whole.
  3. 1599 p. 125 · marginThe dictum is explicitly marked as requiring right interpretation.
  4. 1599 p. 126Corrosive staining is denied the significance of metallic transmutation.
  5. 1599 p. 127The positive salt-stone depends upon regeneration through catholic first matter.

Translation in this edition

Do not translate the philosophical salt-stone as an identified modern crystalline compound. Its colours and wax-flowing description are properties asserted of the proposed regenerated end, not sufficient analytical criteria for recognizing an unknown specimen.

Source note

The page 125 medicinal concession and the page 127 transmuting claim concern different statuses. The former does not prove the latter, and neither supplies present-day medical validation.
