Animal glue

Animal glue is a glue made from collagen, a protein released by boiling the bones, hides and muscles of animals.
It is also called bone glue or hide glue.
Animal glue was most common woodworking glue for thousands of years until the advent of syntetic glues such as polyvinyl acetate (PVA) and other resin glues in the 20th century.
Glass artists use hide glue to bond glass. As the glue hardens it shrinks , chipping the glass.
