…melted metals, the molten would stick to the electrodes making it impossible for the electric currents to go trough. This could be overcome by heating the electrodes before sticking them into the experiment.
The other possible error is that if the metal is not melted enough for the electrodes to conduct. This could be overcome by using a thermometer to measure the amount of heat in the molten and check to see its melting point.
