Historical Definition

Ignis pruinus adeptus is the quintessence of vitriol rectified with tartar.

Meaning

The entry identifies a prepared subject through material and treatment. Vitriol supplies the stated source of the quintessence, while tartar enters the qualification concerning rectification. The definition does not give proportions, stages or a final physical appearance.

The fire name therefore leads to preparation vocabulary rather than directly to the element or a visible flame. Retaining the full headword is important because the neighbouring Ignis entries concern different subjects.

Use in the Book

Essentia quinta explains quintessence through extraction, purification and a claim of incorruptibility. Tartarum itself has a broad range, from wine-vessel dregs to bodily stones. Colcothar gives another vitriolic preparation with a different stated condition. These comparisons clarify the vocabulary while leaving the specific preparation under this heading uncompleted.

Places to Read

Colcothar. Vitriol named through calcination or through the residue of its oil.

Essentia quinta. Quintessence described through extraction, purification and claimed incorruptibility.

Ignis leonis. A fire name directly identified with the element.

In This Edition

“Rectified with tartar” remains a historical relation of treatment. The edition supplies no reconstruction or analytical identity beyond the wording of the source.
