    Alternatives to Bentonite clay

    Gday I am having issues finding fine ground Bentonite clay and need an alternative quick. Even looking through face mask suppliers it's expensive and takes ages to get here. I don't have the time to muck around grinding up kitty litter. Any ideas? Help appreciated.
