Historical definition

Colliquation is melting, as metals are melted.

Meaning

The metal example fixes the sense of a word that might otherwise be mistaken for any passage into a liquid condition. It describes melting, rather than the dictionary’s distinct account of dissolving a coagulated body in a cold place.

Use in the book

Fusio is the close parallel: it means melting or making something flow in fire. Deliquium names cold dissolution. Read together, the entries encourage attention to how a material becomes liquid, without supplying temperatures or a universal scheme of physical states.
