Agglutination
The act of uniting, by means of some viscous substance, as glue, molasses, etc., which causes an adhesion or sticking together of parts or particles which of themselves have no adhesiveness. Silica-sand with molasses; the various free-sands for cores with glue, flour, rosin, etc., are familiar examples of agglutinants, and their usefulness in foundry practice. See CORE-SAND; FLOUR; GLUE.
