Dictionary of Explosives

by Arthur Marshall

In [Gelatine Dynamite] the nitroglycerine is gelatinised with collodion cotton. See under [Gelatine].

American Dynamites are not generally gelatinised with collodion cotton. They are made in a number of grades, depending on the percentage of nitroglycerine.

For further details about various dynamites, see textbooks on explosives.
