_Date of Permit_ 1-9-13 Nitroglycerine 22·3 Nitrocotton 0·7 Di- and trinitro-toluenes 3·5 Potassium perchlorate 37 Wood meal 11·5 Ammonium oxalate 25 Limit charge 12 oz. Power (swing of ballistic pendulum) 2·69” In 1914, 329,000 lbs. were used in coal mines, but the permit has now been repealed. =ALBIONITE.=--A mixture of gelignite and ammonium oxalate. It was formerly on the Permitted List. =ALBIT.=--A German chlorate explosive introduced in 1915 in consequence of the scarcity of nitrates due to the War. It is defined as consisting of not more than 80 per cent. sodium or potassium chlorate, not more than 4 per cent. nitroglycerine, and mono- or dinitro-hydrocarbons. It may also contain inorganic salts and carbon carriers such as vegetable meal, oils, soaps or carbohydrates. A variety made for use in coal mines is called Wetter-Albit or Kohlen-Albit. =ALDORFIT.= See =DORFIT=. =ALKALSIT.=--A German chlorate or perchlorate explosive made by the Dynamit A.-G. of Hamburg. It contains not more than 80 per cent. sodium or potassium chlorate, or not more than 80 per cent. sodium, potassium or ammonium perchlorate, and 19 per cent. of aromatic nitro-hydrocarbons and nitrocotton, also coal, hydrocarbons or carbohydrates, and nitrates. The chlorate mixtures must not contain ammonium salts. Alkalsit I contains not more than 27 per cent. of potassium perchlorate, ammonium nitrate, not more than 24 per cent. of sodium nitrate, not more than 8 per cent. of trinitro-toluene, also wood meal, flour and nitro-naphthalene. Alkalsit A contains not more than 55 per cent. of potassium perchlorate, ammonium nitrate, not more than 31 per cent. trinitro-toluene, and not more than 5 per cent. of a neutral liquid mixture of nitrated toluenes. Alkalsit B is similar except that it contains also ammonium nitrate. =ALSILITE S.G.P.=--A Belgian coal-mine explosive on the list of Explosifs S.G.P. It is of the Ammonal type-- Ammonium nitrate 62 Trinitro-toluene 11 Ferro-silicon-aluminium 5 Sodium chloride 22 Charge limite 900 g. =ALUMATOL.=--A mixture of ammonium nitrate, trinitro-toluene and a little aluminium powder, used for charging trench-mortar bombs, etc. =AMASITE.=--A coal-mine explosive formerly on the Permitted List-- Ammonium perchlorate 34 Sodium nitrate 31 Myrobolans 34·7 Agar agar 0·3 It was made by the Société Anonyme de Vilvorde in Belgium, and was originally called Ugolite. Rock Amasite and S.T. Amasite are non-permitted explosives of composition somewhat similar to the above.
