The Ignition of Fire Damp by Explosives: A Study of the Process of Ignition by the Schlieren Method

Description: From Introduction: "The rupture of this paper by the explosion provided by the explosion provided rapid release for the pressure developed. The charge of explosive was placed in the bore of a cannon communicating with the gallery through a central hole in the steel plate. The apparatus is shown in Figures 1 and 2, which are reproduced from Perrott and Gawthrop's paper. In the event of a nonignition the flame from the explosive only was recorded."
