Note: Both spellings, gelatin and gelatine, are in good use,
but the tendency of writers on physiological chemistry
favors the form in -in, as in the United States
Dispensatory, the United States Pharmacop[oe]ia,
Fownes' Watts' Chemistry, Brande & Cox's Dictionary.
{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.
(c) (Print. or Copying) A method of producing facsimile
copies of an original, written or drawn in aniline ink
upon paper, thence transferred to a cake of gelatin
softened with glycerin, from which impressions are taken
upon ordinary paper.
{Vegetable gelatin}. See {Gliadin}.
