A strong, liquid adhesive originally made from animal protein. Now the term 'glue' is generally used for any type of adhesive, expecially water-based formulations. Animal glue has been made from ancient times by boiling animal hides, tendons, bones, and hooves in water. The collagen is hydrolyzed to form a semitransparent gelatin. Animal glues are applied hot and bind on cooling to form a strong, flexible and water-resistant join. Often glycerin or sorbitol is added as a plasticizer and phenols are added as preservatives to minimize biological growth. Top-quality animal glues are made from rabbitskin, sturgeon bladders, and parchment clippings. Hide glues are used in the manufacture of wood joinery, book binding, abrasive papers, gummed paper and matches. Bone glues are used as carton and box adhesives. See also vegetable glue.
