Ammonium nitrate 63·25 Potassium nitrate 17·5 Collodion cotton 9·25 Chromium ammonium alum 9·5 Vaseline 0·5 =*CLERMONITE.=--A Belgian shot-gun powder made by the Cooppal Co. It is a 40-grain fibrous powder of the bulk type and coloured green. =CLIFFITE= was a coal-mine explosive made by Curtis’s and Harvey, and formerly on the Permitted List-- Nitroglycerine 47 Collodion cotton 3 Starch 50 =SUPER-CLIFFITE= differs considerably from this. There are two formulæ which have passed the Rotherham Test, but only No. 2 is still on the Permitted List-- No. 1. No. 2. _Date of Permit_ 21-9-16 21-9-16 Nitroglycerine 9·5 9·5 Collodion cotton 0·5 0·5 Ammonium nitrate 59 59·5 Wood meal 6 6 Sodium chloride 15 19·5 Ammonium oxalate 10 5 Limit charge 26 30 oz. Power (swing of ballistic pendulum) 2·53 2·53” =CLYDITE= was a coal-mine explosive formerly made by Nobels at Ardeer. It was similar to Nobel Carbonite, but the potassium nitrate was replaced by the barium salt, and it might contain up to 8 per cent. of ammonium oxalate. =COALITE.=--There is a series of coal-mine explosives of this name on the American Permissible List. Varieties X, 3X, and 3XC are ammonium nitrate explosives; whereas 1, 2D, 2DL and 2MLF are nitroglycerine explosives. =COAL SPECIAL= are American coal-mine explosives on the Permissible List. They are all nitroglycerine explosives. =COCOA POWDER= or Brown Powder was a variety of gunpowder made with a brown charcoal prepared from straw-- Potassium nitrate 79 Sulphur 3 Straw charcoal 18 It was compressed to a density of 1·8 into prisms or grains of considerable size, and was used in guns of large calibre. E.X.E. and S.B.C. were special varieties of this. =COLINIT ANTIGRISOUTEUSE.=--A Belgian coal-mine explosive of the Carbonite type. The ordinary formula is practically the same as that of Kohlencarbonite and Minerite. Type B consists of-- Blasting gelatine 26 Potassium perchlorate 6 Ammonium nitrate 20 Trinitro-toluene 12 Rye flour and cellulose 29 Magnesium sulphate 7 =COLLIER POWDER.=--There are a number of coal-mine explosives of this name on the American Permissible List. Varieties BNF, KN, X, XLF, 5, 5LF, 5 Special, 9, 11, and 11LF are ammonium nitrate explosives whereas 2 and 6LF are nitroglycerine explosives. =COLLODION COTTON= is a variety of nitrocotton of low nitration, almost completely soluble in a mixture of ether and alcohol. It contains not more than 12·3 per cent. of nitrogen. It also dissolves in nitroglycerine and liquid nitro-compounds, rendering them gelatinous and so preventing their exudation.
