From The Collaborative International Dictionary of English v.0.48 :

  Blowpipe \Blow"pipe`\, n.
     1. A tube for directing a jet of air into a fire or into the
        flame of a lamp or candle, so as to concentrate the heat
        on some object.
        [1913 Webster]
  
     Note: It is called a mouth blowpipe when used with the mouth;
           but for both chemical and industrial purposes, it is
           often worked by a bellows or other contrivance. The
           common mouth blowpipe is a tapering tube with a very
           small orifice at the end to be inserted in the flame.
           The oxyhydrogen blowpipe, invented by Dr. Hare in
           1801, is an instrument in which oxygen and hydrogen,
           taken from separate reservoirs, in the proportions of
           two volumes of hydrogen to one of oxygen, are burned in
           a jet, under pressure. It gives a heat that will
           consume the diamond, fuse platinum, and dissipate in
           vapor, or in gaseous forms, most known substances.
           [1913 Webster]
  
     2. A blowgun; a blowtube.
        [1913 Webster]
  
     Blowpipe analysis (Chem.), analysis by means of the
        blowpipe.
  
     Blowpipe reaction (Chem.), the characteristic behavior of a
        substance subjected to a test by means of the blowpipe.
        [1913 Webster]
