Tonite (explosive)

Tonite is an explosive[1] sometimes used in the late 19th and early 20th centuries. It consists of a mixture of equal weights of barium nitrate and guncotton.[2] The explosive was patented in 1874[3] by Messrs Trench, Faure, and Mackie.[4] The high gas pressures generated by detonation of tonite resulted in it being used as a bursting charge for some early hand grenades used in World War I. Its name was taken from the Latin verb tonat = "it thunders", and is pronounced "toe-nite" and not as "tonight".

Nitrocellulose is an oxygen-negative low explosive, so its decomposition is incomplete combustion:

Since nitrocellulose was used in mining the carbon monoxide could build up and pose a danger to miners. To remedy this problem, nitrates (potassium nitrate, barium nitrate, ammonium nitrate, etc.) were added into the nitrocellulose to allow for complete combustion.
