The dc electrical transport properties of the nonconventional lead cuprate glasses of compositions (CuO)x(PbO)100-x for x=15-50 mol% are reported in the temperature range 150-500 K. The experimental results have been analyzed in the light of existing theoretical models. It has been observed that the high-temperature conductivity data are consistent with Mott's nearest-neighbor hopping model, while at low temperatures Mott's variable-range-hopping model fits the data very well. The polaron hopping models of Schnakenberg and Emin can predict the conductivity data in the entire temperature range of measurement. The percolation model of Triberis and Friedman is not consistent with the experimental results.
