The discovery of the lining effect and the development of the lined hollow shaped charge are described. While performing experiments designed to increase the kinetic energy of gas clouds entering the cavity of a hollowed explosive charge, a glass cavity liner was used to facilitate evacuation of the cavity. Deeper penetrations of a Silumin test block were obtained with the glass liner. This effect was initially attributed to the vacuum, but further testing indicated that the vacuum had no measurable influence and that the glass liner was responsible. A secret patent no. 18843, dated 9 December 1939 was obtained for an explosive projectile, in whose explosive charge a cavity was formed to increase the explosive effectiveness and which was characterized by a lining of the cavity.
