Publisher Summary This chapter discusses the methods of Kaolin investigation. Methods of kaolin investigation may be organized in several ways: field geology (EFH2) and pedology, laboratory, and industrial and engineering. Brains and Black Boxes (BBB) refers to methods and equipment used in the laboratory and for greatest appeal in grantsmanship. The method of investigation used for field use was geobotanical. Other methods and techniques for field use include geologic and geomorphic environment, field mapping of petrologic units, aerial photos, use of pollen and spores, geologic ages of rocks, sedimentologic facies, and others. The methods of investigating bulk or lump kaolin from the mine emphasize properties of the kaolin in the natural-lump state are natural lump density, inter-crystallinity, cohesion, etc., which are lost in the process of pulverizing the kaolin. Optical methods of investigation include identification, solid impurities, textural relations to parent rock, electrically oriented double-refraction, and dark-field microscopy.
