Abstract
The electrical conductivity of various molten materials was measured using some new and inexpensive conductivity testing devices. This paper illustrates the observation that ionic substances do not conduct in the solid state but do conduct in the molten state, where the ions are mobile. Carveth's mixture of NaNO3, LiNO3, and KNO3 melts at 120 °C, a very convenient temperature for a molten salt.
