Part 5

=ANCHORITE.=--A coal-mine explosive of the Favier type, formerly on the Permitted List. It was made by Kynoch-Arklow, Ltd.

Date of Permit 13-5-14 Ammonium nitrate 34·3 Sodium nitrate 33·3 Ammonium chloride 20·2 Trinitro-toluene 12·2

Limit charge 14 oz. Power (swing of ballistic pendulum) 2·73”

=ANILIT.=--A German explosive containing not less than 70 per cent. of ammonium nitrate, not more than 5 per cent. of sugar, and copper sulphate-aniline or copper oxalate-aniline.

=ANILITE.=--A French liquid explosive of the Sprengel class used for aerial bombs.

=ANTIGEL DE SÛRETÉ.=--A Belgian coal-mine explosive--

Nitroglycerine 25 Sodium nitrate 20 Dinitro-toluene 15 Ammonium sulphate 5 Cellulose } Wood meal } 35

The Charge limite is 900 grammes, which is equivalent to 524 grammes of dynamite No. 1. The composition is the same as that of Ingélite. It is a low-freezing nitroglycerine explosive.

=APHOSITE.=--A coal-mine explosive formerly on the Permitted List--

Ammonium nitrate 60 Potassium nitrate 29·5 Charcoal 4 Wood meal 4 Sulphur 2·5

*=APYRITE.=--A nitrocellulose smokeless powder formerly made in Sweden by the Société Grakrut.

=ARKITE.=--A coal-mine explosive made by Kynoch, Ltd. The original composition which passed the Woolwich Test was--

Nitroglycerine 52·5 Nitrocotton 3·5 Potassium nitrate 22 Wood meal 7 Ammonium oxalate 15

The proportions were modified, and the following passed the Rotherham Test, and was on the Permitted List--

ARKITE NO. 2.

Date of Permit 7-4-14 Nitroglycerine 32 Nitrocotton 1 Potassium nitrate 27 Wood meal 10 Ammonium oxalate 30

Limit charge 40 oz. Power (swing of ballistic pendulum) 2·41”

It has now been repealed.

=ASTRALIT.=--An ammonium nitrate explosive containing a little blasting gelatine, made by the Dynamit A. G. Nobel of Hamburg. It has been used largely in Germany for a variety of purposes.

Astralit I and II are defined as consisting of ammonium nitrate, charcoal, vegetable meal, not more than 15 per cent. of aromatic nitro-bodies not more dangerous than trinitro-toluene, not more than 4 per cent. of blasting gelatine; also paraffin oil.

Astralit IV consists of ammonium nitrate, not more than 10 per cent. of aromatic nitro-bodies not more dangerous than dinitro-naphthalene, vegetable meal, and not more than 4 per cent. of blasting gelatine.

Astralit V, which has been introduced recently, contains up to 10 per cent. of potassium perchlorate in addition to ammonium nitrate, also vegetable meal, not more than 16 per cent. of aromatic nitro-compounds, and not more than 4 per cent. of nitroglycerine.

Gelatine-Astralit is a gelatinised or powdery mixture of the nitrates of ammonium and sodium (or potassium), not more than 50 per cent. of dinitro-chlorhydrin, not more than 5 per cent. of nitroglycerine, not more than 2 per cent. of collodion cotton, vegetable meal, aromatic nitro-bodies such as nitro-toluenes or nitro-naphthalenes, but not more than 4 per cent. of trinitro-toluene; also hydrocarbons.

Wetter-Astralit is a coal-mine explosive, and differs from Astralit in that part of the ammonium nitrate is replaced by sodium chloride.

Wetter-Gelatine-Astralit is also a coal-mine explosive, and differs from Gelatine-Astralit in that it contains also fatty oils and neutral salts, such as potassium chloride, sodium chloride or an oxalate.

The following percentage compositions have been given--
