Part 35

=THORNIT.=--A German blasting explosive consisting of ammonium nitrate and vegetable meal. It may also contain animal or vegetable fats.

=TITANITE.=--A coal-mine explosive manufactured in Hungary. A variety of it was on the old British Permitted List--

Ammonium nitrate 87 Trinitro-toluene 7 Curcuma charcoal 6

Other varieties containing a smaller percentage of ammonium nitrate have been used for general blasting.

=T.N.T.= stands for trinitro-toluene or trotyl.

=TOLITE= stands for trinitro-toluene.

=TONITE=, or Cotton Powder, is a blasting explosive which was much used at one time. It consists of guncotton mixed with a nitrate and compressed into blocks or cylinders, but a small percentage of a nitro-compound has sometimes been added. A Belgian Tonite had the composition--

Guncotton 53·0 Barium nitrate 37·6 Sodium nitrate 9·4

That made by the Cotton Powder Co. consists of--

Guncotton 50 Barium nitrate 50

=TOXOL= is a high explosive, a mixture of trinitro-xylene and trinitro-toluene.

=TREMONIT= is a German coal-mine explosive containing gelatinised dinitro-glycerine, e.g.--

Tremonit S II. Dinitro-glycerine 33 Collodion cotton 1 Trinitro-toluene 2·5 Ammonium nitrate 26·5 Pea flour 12 Sodium chloride 25

Ammon-Tremonit or Gesteins-Tremonit contains a considerable proportion of ammonium nitrate.

Gesteins-Tremonit V. contains also up to 10 per cent. of potassium perchlorate, and is similar to Astralit V.

=TRINOL.=--A name for trinitro-toluene.

=TRIPLASTIT= was a plastic high explosive obtained by gelatinising a liquid or semi-liquid mixture of nitro-toluenes with collodion cotton and mixing it with lead nitrates, e.g.--

Nitro-toluenes 70 Collodion cotton 1·2 Lead nitrate 28·8

It was intended for filling shell, etc.

*=TROISDORF SMOKELESS POWDER= became prominent in England in 1897 in connection with Mannlicher cartridges for the Bisley long-range competitions. It was occasionally recorded as Pigou Wilkes Powder, as that firm were agents for it. The following are analyses of samples taken in 1898 (“Arms and Explosives,” 1917, p. 90)--

Shot-gun Rifle Powder. Powder.

Nitrocellulose, insoluble 24·9 1·5 ” soluble 61·7 96·5 Starch, agar and dye 11·5 -- Moisture 1·9 2·0

The shot-gun powder was a fibrous bulk powder, and the charge for a 12-bore cartridge was 33 grains. The rifle powder was gelatinised.

=TROJAN COAL POWDER= is an American coal-mine explosive on the Permissible List. It contains nitro-starch.

=TROTYL= is a name for trinitro-toluene.

=TUNNELIT= is a German safety explosive containing ammonium nitrate, sodium nitrate, not more than 10 per cent. of trinitro-toluene (or not more than 6 per cent. together with not more than 2 per cent. of neutral liquid trinitro-toluene), not more than 20 per cent. of dinitro-chlorhydrin, not more than 5 per cent. of nitroglycerine, not more than 1 per cent. of collodion cotton, and carbohydrates.

=TUNNELITE= is an American coal-mine explosive on the Permissible List. Brands AA, B and C are ammonium nitrate explosives, whereas numbers 3 to 8, 6LF and 8LF are nitroglycerine explosives.
