Historical Definition

Calx lignorum is wood ash.

Meaning

The starting material is explicit, making this a useful anchor within the broad Calx vocabulary. Here the term does concern ash, whereas other compounds in the dictionary identify spirits, precipitates or different prepared materials. Read the complete expression rather than assume one meaning for every Calx.

Alcali provides the next operational connection: salts can be extracted from ashes or calx in its account. The ash and the salt obtained from it remain distinct materials or stages, even when one leads to the other.

Places to Read

Alcali. Salt defined through extraction from ash or calx.

Cinificatum. A material reduced to ash by burning.
