=*WALSRODE SHOT-GUN POWDER= was a gelatinised 28-grain dense
powder, which the German makers endeavoured to introduce into England
in the ’nineties, but it gave high pressures. A powder of this name
is still used in Germany, however, but it is a 35-grain powder in the
form of small grains, greyish white and greyish green in colour.
=WALSRODE SICHERHEITS-SPRENGSTOFF= is a German coal-mine
explosive containing ammonium nitrate, trinitro-toluene, flour, and a
little guncotton and sometimes sodium chloride.
Wetter-Walsrode is also an ammonium nitrate explosive. It contains
no guncotton but may contain potassium nitrate, sodium chloride,
naphthalene, and various other substances.
=WESTFALITE= is a coal-mine explosive which is made in Germany
and England. The German explosives vary much in composition, and some
of them are intended for ordinary blasting. Some of those recently
introduced contain up to 10 per cent. of potassium perchlorate.
Originally Westfalite was made by milling ammonium nitrate with an
alcoholic solution of gum lac, but later the use of the gum was
abandoned.
