| 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 |
