Results are presented of temperature studies of electric conductivity, for a few frequencies from 100 Hz to 100 kHz, in liquid glass-formers: dibutyl phthalate, glycerol and salol. It has been shown that the analysis of experimental data similar to that applied in non-critical liquid mixtures of limited miscibility may offer a relatively precise and simple estimation of the mode-coupling critical temperature (T<sub>C</sub>) and exponent (). Preliminary pressure studies point to the possibility of isomorphic behaviour for the temperature and the pressure paths approaching the mode-coupling critical point.
