Historical Definition
Grilla, or Grillus, is vitriol dissolved of its own accord into water.
Meaning
The definition identifies a condition of vitriol and preserves the claim that the dissolution occurs of its own accord. It does not state the surrounding conditions or identify a particular specimen of vitriol. The phrase should not be expanded into an assertion that every material given that historical name behaves identically.
Use in the Book
Deliquium concerns dissolution in a cold place, while Colcothar names calcined vitriol or the residue associated with its oil. Their different qualifications show why one general starting name can enter several distinct material descriptions. Grilla specifically concerns the dissolved condition stated here.
Places to Read
Colcothar. Vitriol named through calcination or through the residue of its oil.
Deliquium. Dissolution of a coagulated body in a cold setting.
