A 23,five hundred instances magnified electron micrograph of smectite clay The defining mechanical house of clay is its plasticity when moist and its capability to harden when dried or fired. Clays present a broad array of water material inside of which They may be extremely plastic, from a minimum amount drinking water written content (known as the plastic Restrict) wherever the clay is simply moist ample to mould, into a highest water content (known as the liquid Restrict) in which the moulded clay is just dry sufficient to carry its condition.

If the clay is dried, the majority of the h2o molecules are removed, along with the plates form direct hydrogen bonds with one another, earning the dried clay rigid but still fragile. In the event the clay is moistened yet again, it will eventually over again turn out to be plastic. In the event the clay is fired to the earthenware stage, a dehydration reaction removes further drinking water in the clay, creating clay plates to irreversibly adhere to one another through more robust covalent bonding, which strengthens the material. The clay mineral kaolinite is reworked into a non-clay product, metakaolin, which remains rigid and tricky if moistened once again. Further more firing in the stoneware and porcelain levels even further recrystallizes the metakaolin into still more robust minerals like mullite.[6]
