| Ammonium nitrate | 83·4 |
| Dinitro-benzene | 16·5 |

GEHLINGERIT.—A German blasting explosive. Gesteins-Gehlingerit III. contains—
| Ammonium nitrate | 80 |
| Trinitro-toluene | 15 |
| Flour | 5 |
Wetter-Gehlingerit, which is a coal-mine explosive, contains also sodium or potassium chloride, and may contain up to 4 per cent. of nitroglycerine to increase its sensitiveness.
GELATINÉ À L’AMMONIAQUE.—A Belgian explosive, a mixture of [blasting gelatine] and ammonium nitrate.
GELATINE DYNAMITE is a mixture of [blasting gelatine], potassium nitrate and a little wood meal. That made in Britain must contain between 70 and 77 per cent. of nitroglycerine; it may contain up to 2 per cent. of calcium or magnesium carbonate, or 1/2 per cent. of mineral jelly as a stabiliser. The following may be taken as an example of its composition—
| Nitroglycerine | 74·5 |
| Collodion cotton | 5·5 |
| Wood meal | 4 |
| Potassium nitrate | 15·5 |
| Calcium carbonate | 0·2 |
| Moisture | 0·3 |
In America brands are made of 35 to 80 per cent. strength.
GELIGNITE is similar to [Gelatine Dynamite] except that it contains a smaller proportion of blasting gelatine; in Britain the percentage of nitroglycerine must be between 56 and 63, e. g.—
| Nitroglycerine | 61 |
| Collodion cotton | 4·5 |
| Wood meal | 7 |
| Potassium nitrate | 27 |
| Calcium carbonate | 0·2 |
| Moisture | 0·3 |
