Pairs of crystals were grown simultaneously from melts of sodium chloride containing various amounts of divalent cation impurity. One of the crystals of each pair was grown from a distorted seed in an attempt to introduce extra dislocations into this crystal. The electrical conductivities of samples cleaved from each of the crystals were measured in a temperature range from 100°C to 300°C. A comparison of the results of these measurements indicated that there was a slight extra conductivity in the crystals grown from the bent seeds.
