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. 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. =DYNAMITE ANTIGRISOUTEUSE.=--Belgian coal-mine explosive made at Baelen Wezel-- IV. V.
