Abstract
ACCORDING to Voigt1, the quartz crystal cracks along the rhombohedral surfaces (r) when suddenly cooled from high temperatures. Seidl2 reported for a quartz plate of x-cut a case in which the thermal cracking showed a zigzag path made up of segments nearly parallel to these surfaces. Schubnikow3 obtained cracks in two directions by applying pressures on an x-cut quartz plate. These cracks are stated to be parallel to the rhombohedral surfaces, although his photograph seems to indicate that the angles between the cracks are smaller than the rhombohedral angle (84° 12' ). Hirata4 obtained cracks like networks on a quartz plate of x-cut and on natural prismatic surfaces by electric discharges in water, the direction of the spark being parallel to the surface of the plate.
