   Note: Ordinarily, black ink is made from nutgalls and a
         solution of some salt of iron, and consists essentially
         of a tannate or gallate of iron; sometimes indigo
         sulphate, or other coloring matter, is added. Other
         black inks contain potassium chromate, and extract of
         logwood, salts of vanadium, etc. Blue ink is usually a
         solution of Prussian blue. Red ink was formerly made
         from carmine (cochineal), Brazil wood, etc., but
         potassium eosin is now used. Also red, blue, violet,
         and yellow inks are largely made from aniline dyes.
         Indelible ink is usually a weak solution of silver
         nitrate, but carbon in the form of lampblack or India
         ink, salts of molybdenum, vanadium, etc., are also
         used. Sympathetic inks may be made of milk, salts of
         cobalt, etc. See Sympathetic ink (below).

The Devil's Dictionary (1881-1906):

INK, n.  A villainous compound of tannogallate of iron, gum-arabic and
water, chiefly used to facilitate the infection of idiocy and promote
intellectual crime.  The properties of ink are peculiar and
contradictory:  it may be used to make reputations and unmake them; to
blacken them and to make them white; but it is most generally and
acceptably employed as a mortar to bind together the stones of an
edifice of fame, and as a whitewash to conceal afterward the rascal
quality of the material.  There are men called journalists who have
established ink baths which some persons pay money to get into, others
to get out of.  Not infrequently it occurs that a person who has paid
to get in pays twice as much to get out.
