My Flashcards

Definition

Meaning

A bath containing water mixed with a high concentration of salt, especially for therapeutic, cosmetic, or industrial purposes.

Any solution or environment where salt is the primary agent for treatment, such as in metallurgical processes for heat-treating metals, culinary brining, or chemical manufacturing. Conceptually, it implies immersion in a specialized saline medium for a transformative purpose.
