Extract

Suspensions of clays in organic liquids change considerably in rheological character from liquid to liquid or when additions of a second liquid are made; thus, for example when about 15 per cent. volume of ethyl alcohol was added to a dispersion of a sample of bentonite in water the specific viscosity and thixotropy (as measured by rate of the sol→gel transition) increased to a maximum in spite of the-fact that alcohol itself yielded low viscosity suspensions.
