Excerpt from Fuller's Earth In 1891 fuller's earth was discovered in Arkansas by John Olson. Who still mines earth near Benton, Ark. In 1893 fuller's earth was discovered at Quincy, F 1a., which proved to be especially applicable to the bleaching of petroleum. The deposits near Quincy, together with others in the neighboring parts of Florida and southwestern Georgia, have from that time furnished all of the fuller's earth used in the refining of mineral oils in this country. The Florida earths have, however, never been extensively applied to the bleaching of fats and vegetable oils. The Arkansas earth is used wholly for edible oils. Since the discovery of the Florida earths many other deposits of clays with marked bleaching power have been found in other States.
