Abstract
A kaolin clay slurry having a reduced viscosity is manufactured by a process which comprises the sequential steps of mechanically working an undispersed crude kaolin clay material having a solids content of at least about 65 percent, by weight, under conditions which insure that the kaolin clay material will be subjected to an energy level of at least 10 horsepower-hours per ton of dry kaolin clay material and then subjecting the mechanically worked kaolin clay material to centrifugation to substantially remove any particles having a diameter less than about 0.2 microns.
