Thermal Etching on Ice Crystals

Thermal etching is studied in pure ice and ice doped with NaCl. Previous work indicates that etch pits on the ice surface, which show the orientation of the crystals, may be obtained using the formvar technique. In the present work, the evaporation rate is controlled by keeping the samples in nearly...
