Silesia explosive

Silesia Explosives. See under Colophony or Rosin and Colophony, Nitrated in Vol 3, C403-R to C404-L and under Chlorate Explosives in Vol 2, C206-R... 

In Upper Silesia, in the summer of 1921, while unloading caked ammonium nitrate from a railway car in order to make the work easier shot holes were bored in the material, and charged with an ammonium nitrate explosive, whereupon the charges were exploded. The detonation of these charges was followed by the detonation of ammonium nitrate contained in the car. The detonation was transmitted to ammonium nitrate in the neighbouring car. This accident claimed numerous victims and was accompanied by appreciable material damage. 

Silesia Powder (186,829, T902, D.R. Patent) is a mixture of 75 percent, potassium chlorate and pure or nitrated resin. Permonite and Alkalsite contain 25-32 per cent, potassium perchlorate, ammonium nitrate, trinitro-toluene, and other constituents. Yonckite, a Belgian explosive, contains, in addition to perchlorate, potassium nitrate and mononitronaphthalene.
