Calcined Kaolin
Calcination initially converts it to metakaolin (whose reactivity makes it useful in cements). Further heating whitens it more and reduces reactivity while still keeping abrasiveness low. Still, more calcination converts the crystals to mullite, making them much more abrasive. Calcined kaolin has an important use in ceramic glazes.
