ter from oil. There are three common types of bleaching clays: fuller's earth, activated clays, and activated bauxite. Fuller's earth, or naturally active clay, is prepared from ben- ' tonite~ that possess natural activity. It is not activated commercially; in fact, earths of this type ordinarily do not respond satisfactorily to acid
