There are a number of explosives of this type made in other countries also, but they usually contain small proportions of combustible substances such as wood meal, and nitro-bodies such as trinitro-toluene. Of British explosives of this type, mention may be made of Monobel, Super-Excellite and Monarkite. German explosives of this sort include Salit, Tremonit, Donarit, Ammon-Karbonit and Astralit. On the Belgian list of Explosifs S.G.P. is Grisoutine II., which is identical in composition with Dynamite anti-grisouteuse V. =GRISOUTITE.=--A Belgian coal-mine explosive-- Nitroglycerine 44 Magnesium sulphate 44 Cellulose 12 Charge limite 300 g. =GUARDIAN.=--American coal-mine explosives. Nos. 2, 2X, 3 and 3X are ammonium nitrate explosives, whereas Guardian A and Guardian Coal Powder B are nitroglycerine explosives. =GUNCOTTON.=--A highly nitrated cotton containing about 13 per cent. of nitrogen and only slightly soluble in ether-alcohol. =GUNPOWDER.= See =BLACK POWDER=. =*HALAKITE= attracted public attention out of all proportion to its merits, of which it possessed none, in consequence of the extravagant claims made on its behalf by its “inventors” and their dupes. Early in 1917 the British Government caused an inquiry to be held, and the case for the explosive collapsed in a ludicrous manner. According to patent specification, No. 685 of 1915, the basis of the explosive was an admixture of lead nitrate with glycerine and other substances, and under the working conditions the glycerine was said to react with the nitrate to form a nitro-compound, which, of course, is not true. The substance actually submitted to the British and French authorities consisted of cordite mixed with lead nitrate, barium nitrate and lead chromate. This was stated by the promoters to be equally effective as a high explosive and a propellant! See “Interim and Final Reports of the Army Council (Halakite) Inquiry,” Cd. 8446. =HALALIT.=--A German blasting explosive made by Nahnsen, containing not more than 65 per cent. of potassium perchlorate, ammonium nitrate, and not more than 32 per cent. of nitrated toluene, of which not more than 20 per cent. must be trinitro-toluene. It may also contain collodion cotton to gelatinise the liquid nitro-toluene, and sodium nitrate and wood meal or other vegetable meal. Ammon-Halalit A, which has been introduced recently, is similar to Astralit V. =HALOKLASTIT.= See =PETROKLASTIT=. =HAMMONIT.=--A German blasting explosive containing not more than 40 per cent. of potassium or sodium perchlorate, not more than 4 per cent. of nitroglycerine, aromatic nitro-bodies, ammonium nitrate, sodium or potassium nitrate, neutral salts and vegetable meal or other combustible matter.
