*Poudre T is a condensed smokeless shot-gun powder manufactured by the French Government. It is made from guncotton, [CP1], to which 2 per cent. of saltpetre is added, gelatinised with acetone. The dough is pressed into strips which are rolled down to a thickness of 0·15 mm. and cut into small squares of 1·5 mm. side. The powder is then steeped in water to dissolve out the greater part of the potassium nitrate, dried, and finally drummed with a little gum and graphite to make it more progressive. This powder is superior to the other French sporting-powders, but is more expensive. The charge for a 16-bore cartridge is 1·9 grammes.
TELSIT A is a blasting explosive made at the Nobel Works in Switzerland. It consists of ammonium nitrate, nitrated toluene and aluminium powder.
Gelatine-Telsit contains ammonium nitrate, [blasting gelatine] and liquid trinitro-toluene, also gelatinised with collodion cotton.
Special-Gelatine-Telsit differs from this in having part of the ammonium nitrate replaced by sodium nitrate.
