Monachit II. contains in addition not more than 1 per cent. of collodion cotton, not more than 1 per cent. of charcoal, also hydrocarbons and ammonium oxalate or other salts to act as cooling agents, and render the explosive suitable for use in coal mines, _e. g._-- Ammonium nitrate 81 64 Potassium nitrate 5 3 Nitro-compounds 13 14 Collodion cotton -- 1 Flour 1 -- Charcoal -- 1 Potassium chloride -- 17 The collodion cotton is to gelatinise the nitro-compounds when they are liquid. =MONARKITE= is a coal-mine explosive made by Kynoch, Ltd., and is on the Permitted List-- _Date of Permit_ 10-2-14 _Revised_ 20-9-19 Ammonium nitrate 49[1] Sodium nitrate 9 Nitroglycerine 11·5 Collodion cotton 0·3 Starch 3·5 Mineral jelly 2 Sodium chloride 24·7 Limit charge 18 oz. Power (swing of ballistic pendulum) 2·30” [1] Including not more than 2 per cent. of magnesium carbonate. =MONOBEL= is a coal-mine explosive made by Nobel’s Explosives Co. There are three formulæ which have passed the Rotherham Test, but A1 is no longer on the Permitted List-- Monobel A1 A2 No. 1. Monobel. Monobel. _Date of Permit_ 10-2-14 13-5-14 15-1-15 Ammonium nitrate 68 60 59 Nitroglycerine 8·5 10 10 Wood meal 8·5 10 10 Sodium chloride 15 -- -- Potassium chloride -- 20 20 Magnesium carbonate -- -- 1 Limit charge 10 28 22 oz. Power (swing of ballistic pendulum) 2·81 2·78 2·44” There is also Quarry Monobel which is not permitted for use in dangerous coal mines, and presumably contains no alkali chloride. See also Viking Powder and Victor Powder. =MONOBEL, NOS. 1= to =7= are on the American Permissible List. Of these, Nos. 4 and 5 are low-freezing explosives, containing a small percentage of nitro-toluene or similar substance; Nos. 3 and 5 are less violent than the others. =MONOBEL POWDER= was the predecessor of the above and was on the old Permitted List. It is now no longer “permitted.” Ammonium nitrate 80 Nitroglycerine 10 Wood meal 10 =*MULLERITE.=--A shot-gun powder made by the Muller Co. in Belgium. It is a gelatinised dense powder in the form of green leaflets, and the charge for a 12-bore cartridge was 33 grains. It contains no inorganic salts. =EXPLOSIFS N.= See Favier Explosives.
