Euhedral crystals of kaolinite sere heated to various temperatures, draw trials made at frequent intervals, and the effect of temperature was studied microscopically. The results obtained indicate three classes of kaolinite: (1) the natural kaolinite, (2) the uniaxial form produced at 625°C, the metanacrite of Rinne, and (3) the change of the metanacrite into what is probably mullite and glass at 1450°C.
