Meaning
Grey silver cobalts are a historical ore category in Khunrath’s discussion of wild silver ores and mountain kinds. “Cobalt” here must not be assumed to name modern elemental cobalt.
Use in the book
The materials are rejected as a pri-material ground because they are already specified and may contain foreign mineral or metallic spirits. Their place in the mountain and their immature appearance do not secure the universality being sought.
Places to read
- 1599 p. 76Grey silver cobalts are named with wild silver ores.
- 1599 p. 77Specification and possible admixture explain the objection.
Translation in this edition
The full three-part name is retained. Collapsing it to cobalt erases the historical silver-ore context and imports a modern identification.
Source note
Khunrath describes possible admixture as a concern, not as an analysis proving the composition of every specimen in this category.
