A curious analogy to the boiling to string proof of third molasses is found in the manufacture of chrome alum. It is well known that if molasses be boiled to a high temperature and allowed to cool taffy results, a vitreous noncrystalline mass. In like manner if in concentrating a solution of chrome alum, the evaporation passes a certain point, the mass on cooling assumes a glue-like consistency and refuses to crystallize. In such a case it is necessary to redissolve and reconcentrate carefully.

Glue is derived from collagen, the major proteinaceous component of animal and fish skins, as well as tendons and the proteinaceous matrix of bones. In recent times the important commercial raw materials for making animal glue come from tanneries, which supply limed splits and chrome tanned pieces, and from slaughter houses, which furnish fleshings, hide pieces and bones.
