Animal jelly; glutinous material obtained from animal tissues by prolonged boiling. Specifically ( Physiol. Chem.), a nitrogeneous colloid, not existing as such in the animal body, but formed by the hydrating action of boiling water on the collagen of various kinds of connective tissue ( as tendons, bones, ligaments, etc.). Its distinguishing character is that of dissolving in hot water, and forming a jelly on cooling. It is an important ingredient of calf' s- foot jelly, isinglass, glue, etc. It is used as food, but its nutritious qualities are of a low order.

[ 1913 Webster] { Blasting gelatin}, an explosive, containing about ninety- five parts of nitroglycerin and five of collodion. { Gelatin process}, a name applied to a number of processes in the arts, involving the use of gelatin. Especially: ( a) ( Photog.) A dry- plate process in which gelatin is used as a substitute for collodion as the sensitized material. This is the dry- plate process in general use, and plates of extreme sensitiveness are produced by it. ( b) ( Print.) A method of producing photographic copies of drawings, engravings, printed pages, etc., and also of photographic pictures, which can be printed from in a press with ink, or ( in some applications of the process) which can be used as the molds of stereotype or electrotype plates.
