On the capacity and residual charge of dielectrics as affected by temperature and time
John Hopkinson, E. Wilson · Proceedings of the Royal Society of London · 1897
Abstract The major portion of the experiments described in the paper have been made on window glass and ice. It is shown that for long times residual charge diminishes with rise of temperature in the case of glass, but for short times it increases both for glass and ice. The capacity of glass when measured for ordinary durations of time, such as l/100th to l/10th second, increases much with rise of temperature, but when measured for short periods, such as 1/106 second, it does not sensibly increase.
