Clay provides a large content of clay minerals that provide it its plasticity. Clay minerals are hydrous aluminium phyllosilicate minerals, made up of aluminium and silicon ions bonded into very small, slim plates by interconnecting oxygen and hydroxide ions. These plates are difficult but versatile, and in moist clay, they adhere to one another. The ensuing aggregates give clay the cohesion which makes it plastic.[14] In kaolinite clay, the bonding in between plates is furnished by a movie of water molecules that hydrogen bond the plates together. The bonds are weak adequate to allow the plates to slide past one another once the clay is being moulded, but sturdy ample to carry the plates set up and permit the moulded clay to keep its condition following it's moulded.
