Clay provides a higher content material of clay minerals that give it its plasticity. Clay minerals are hydrous aluminium phyllosilicate minerals, composed of aluminium and silicon ions bonded into very small, slim plates by interconnecting oxygen and hydroxide ions. These plates are tough but adaptable, As well as in moist clay, they adhere to one another. The resulting aggregates give clay the cohesion that makes it plastic.[fourteen] In kaolinite clay, the bonding among plates is provided by a film of water molecules that hydrogen bond the plates alongside one another. The bonds are weak adequate to allow the plates to slide earlier one another if the clay is remaining moulded, but powerful ample to hold the plates set up and permit the moulded clay to keep its form soon after it's moulded.
