Mineral oils, purifying &c.-The sludging of mineral oils used for insulating electric transformers, or capacitors or for other purposes in which the oils are maintained at a high temperature is reduced by contact with fullers' earth. For example, 6 per cent by volume, relative to oil, of the earth is contained in a wire-mesh basket 8 supported on insulating supports 9, 10 below the yoke 7 of the transformers 1, 2 immersed in oil in the tank 3.
