A method for evaluation of edge capacitance of a two-layer dielectric capacitor, with materials of widely different and variable dielectric constants

In a recent study on the change of dielectric constant as a determination of the progress of crystallization of an inorganic compound, a great deal of difficulty had been experienced. The cause lay in the high and continually changing dielectric constant of the specimen and in the necessity of involving the use of a series capacitor and a container both of which had different dielectric constants from each other and from the specimen.
