These plates are hard but adaptable, As well as in moist clay, they adhere to each other. The ensuing aggregates give clay the cohesion which makes it plastic.[fourteen] In kaolinite clay, the bonding concerning plates is supplied by a film of water molecules that hydrogen bond the plates collectively. The bonds are weak adequate to allow the plates to slide past one another once the clay is being moulded, but solid adequate to carry the plates in position and permit the moulded clay to retain its condition right after it is moulded.
