Drying. Below 100 °C (212 °F), exposure to dry air will slowly remove liquid water from the kaolin. The final state of this transformation is called "skin dryness". Between 100 °C and about 550 °C (1,022 °F), the remaining liquid water is expelled from the kaolinite. The final state of this transformation is called "bone dryness".
