=WETTERDYNAMIT= is a name that has been given in Germany to
various coal-mine explosives containing nitroglycerine.
=WETTER-DYNAMMON.= See =DYNAMMON=.
=*WETTEREN.=--A gelatinised rifle smokeless powder made by the
Cooppal Co. of Belgium. The following analyses were given in “Arms
and Explosives,” 1917, p. 91--
_Date of Sample_ 1892 1893
Nitrocellulose, insoluble 16·0 57·3
” soluble 46·2 37·6
Nitroglycerine 27·3 --
Shellac -- 3·5
Charcoal 9·0 --

=WHITE GUNPOWDER= is a mixture of--
Potassium chlorate 50
Potassium ferrocyanide 25
Sugar 25
It is not produced commercially, and, indeed, is too sensitive, but
it is sometimes made in the laboratory. It has also been called
Angendre’s powder, White German powder, American powder, and Baron
and Cauvet’s powder.
=WILHELMIT= is a German blasting explosive of the Cheddite type.
It consists of sodium or potassium chlorate hydrocarbon oil with a
flash point not below 30° C., and carbohydrates. For use in coal
mines neutral salts are added. It was introduced during the War.
=WITHNELL POWDER.=--A coal-mine explosive of the Grisounite type
made by the Lancashire Explosives Co., which was on the old Permitted
List--
Ammonium nitrate 89·5
Trinitro-toluene 5
Flour 5·5
=WITTENBERGER WETTERDYNAMIT.= See =SALIT=.
=XPDITE= is an American coal-mine explosive on the Permissible
List. It is made by the Hercules Powder Co., and contains
nitroglycerine.
=YONCKITE.=--A Belgian ammonium perchlorate explosive. The
composition has been varied somewhat, and one formula, No. 10, is on
the list of Explosifs S.G.P., and consequently is permitted for use
in Belgian coal mines. No. 1 is a more powerful explosive used for
general blasting.
