A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 36; facsimile PDF page 364.

Historical Definition

Obrizum is pure gold calcined by art to a light red colour.

Meaning

The definition names both the material and its prepared state. Pure gold undergoes artificial calcination, and a light red colour belongs to the result described. The colour should not be allowed to replace either the starting subject or the operation.

Use in the Book

Orizeum is an unqualified gold-name, while Orizeum foliatum is leaf-gold. Comparing the full expressions separates a plain equivalent, a physical form and a prepared condition.

Places to Read

Orizeum. A direct gold synonym.

Orizeum foliatum. Gold distinguished by its leaf form.
