The poor plasticity of kaolin is chiefly due to its relatively large particle sizes. Consequently, pre-fired kaolin ceramics can easily tear when bent, if in a moist unfired state (i.e. moisture levels are suboptimal). Of all classes of clay, kaolin has the highest temperature maturity levels (high-fire clay) with temperatures as high as 1,800 °C.
