Historical Definition
Calx Mercurii is precipitated Mercury.
Meaning
The operation is part of the material description. The entry does not equate all Mercury with this calx; it specifies a precipitated form. A historical account may distinguish the starting Mercury, its treatment and the product, and those stages should remain visible in modern English.
Mercurius metallorum præcipitatus offers a related qualified name, while Aquila records a use involving Mercury precipitated with gold. The present definition does not mention gold, so that qualification should not be imported without evidence from the actual passage.
Places to Read
Mercurius metallorum præcipitatus. A preparation specified by metallic extraction followed by precipitation.
Aquila. An eagle-name with more than one stated material meaning.
Mercurius Crudus. Mercury described before separation from its mineral source.
