ABSTRACT OF THE DISCLOSURE Normally nongelling montmorillonite clay is treated to have gelling characteristics by drying the clay to 10 to 15 percent free moisture and grinding the clay to at least 100 percent finer than 45 microns. To thicken an aqueous solution, the clay is dispersed in water with 2 chemical dispersant and the predispersion is agitated in the aqueous liquid with a flocculent. To thicken an organic liquid, the dried and ground clay is stirred into the liquid with a surfactant.
