Suspensions of clays in organic liquids change considerably in rheologicalcharacter from liquid to liquid or when additions of a second liquid aremade; thus, for example when about 15 per cent. volume of ethyl alcohol wasadded to a dispersion of a sample of bentonite in water the specificviscosity and thixotropy (as measured by rate of the sol→gel transition)increased to a maximum in spite of the-fact that alcohol itself yielded lowviscosity suspensions.
