Calx peregrinorum
Salts solvents and liquid preparations · A Chymical Dictionary
At a Glance
The word. A calx expression identified with tartar.
A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 13; facsimile PDF page 341.
Historical Definition
Calx peregrinorum is tartar.
Meaning
This short identification is valuable because it resists a uniform translation of Calx as ordinary lime or ash. Within this compound, the dictionary expressly gives tartar. The complete historical name should therefore be retained in the index, with a route into Tartarum for the larger family.
The entry does not describe the tartar’s source or treatment. Where a recipe adds those details, they belong to that particular use. A bare equivalence should not be expanded into an invented preparation.
Places to Read
Tartarum. A wine-vessel deposit whose name also serves for bodily stones or gravel.
Adamita. An otherwise unspecified variety of tartar.
Alembrot. A purified preparation identified with salt of tartar and its magistery.
