*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.
British Westfalite, Ltd., had two mixtures on the old Permitted List—
| No. 1. | No. 2. | |
| Ammonium nitrate | 95 | 91 |
| Potassium nitrate | — | 4 |
| Resin | 5 | 5 |
That formerly on the Permitted List differed considerably from the above—
| Westfalite No. 3. | |
| Date of Permit | 1-9-13 |
| Ammonium nitrate | 60 |
| Potassium nitrate | 14 |
| Trinitro-toluene | 5 |
| Ammonium chloride | 21 |
Limit charge | 12 oz. |
| Power (swing of ballistic pendulum) | 2·55” |
WETTERDYNAMIT is a name that has been given in Germany to various coal-mine explosives containing nitroglycerine.
