ISINGLASS
is, properly, gelatine prepared from the air or swim bladder of the sturgeon, cod and similar fish, Russia, Brazil and the United States furnishing the bulk of the world's supply. It is employed in fining liquors and the manufacture of fish glue, etc., and in the household in the preparation of jellies, blanc-mange and similar desserts. Gelatine from animal tissue has, however, largely supplanted it in cookery on account of its lower price.
Japanese Isinglass or Gelatine is prepared from a seaweed.
