There are two major types of animal glue, hide glue and bone glue, differing in the type of raw materials used. Although process conditions may differ, both are obtained by hydro­lysis of the collagen in the hide and of connective tissue or bone structure of the raw material. Both types are principally of cattle origin with tanning and meat-packing indus­tries as the principal sources of raw materials.
