DYNAMITE is a name that has been given to various nitroglycerine explosives. Dynamite No. 1 consists of—
| Nitroglycerine | 75 |
| Kieselguhr | 25 |
the explosive being held in the pores of the kieselguhr. In other dynamites the nitroglycerine is absorbed in a material like wood meal, and a nitrate is added to oxidise the latter on explosion.
