Clay features a large information of clay minerals that provide it its plasticity. Clay minerals are hydrous aluminium phyllosilicate minerals, made up of aluminium and silicon ions bonded into tiny, thin plates by interconnecting oxygen and hydroxide ions. These plates are tricky but adaptable, and in moist clay, they adhere to one another. The resulting aggregates give clay the cohesion which makes it plastic.[fourteen] In kaolinite clay, the bonding in between plates is furnished by a film of h2o molecules that hydrogen bond the plates together. The bonds are weak ample to enable the plates to slide earlier each other once the clay is staying moulded, but potent sufficient to carry the plates in position and permit the moulded clay to retain its condition just after it can be moulded.
