transudation
Moisture passing through
Transudation is the passage of fluid through a membrane or tissue, seeping out gradually rather than flowing freely.
In medicine, a transudate is fluid that has passed through vessel walls due to pressure rather than inflammation—distinguished from exudate, which results from injury or disease.
The verb is transude: Moisture transuded through the porous stone.
