May undergo a vigorous reaction with reducing agents, including hydrides, sulfides and nitrides, that culminates in a detonation. Can react with inorganic bases to form explosive salts First, the velocity of the explosion had to be reduced so that the charge weight required to propel the projectile would not shatter the gun tube. Second, the density had to be increased so that a given charge weight would pack into a reasonable space. The first problem was solved in part by igniting nitrocellulose instead of firing it with a detonator. The solution to the second problem. Unfortunately, guncotton or nitrocellulose, like nitroglycerine can be extremely unstable and a number of the factories were destroyed by explosions, putting Schonbein out of business. Again, like nitroglycerine, the major cause of the instability was residual nitric acid and by the 1860s techniques had been established for removing the excess acid by proper washing, after which guncotton. Explosions of flour silos, for example, can be particularly powerful. Basically, any powder that can be oxidized (=burn) can present an ATEX risk under certain conditions.
