When the clay is dried, many of the drinking water molecules are eradicated, as well as plates form immediate hydrogen bonds with one another, earning the dried clay rigid but nonetheless fragile. If the clay is moistened again, it'll once more grow to be plastic. Once the clay is fired towards the earthenware stage, a dehydration reaction gets rid of more drinking water with the clay, resulting in clay plates to irreversibly adhere to each other by way of stronger covalent bonding, which strengthens the fabric. The clay mineral kaolinite is remodeled into a non-clay materials, metakaolin, which continues to be rigid and tricky if moistened yet again. Even more firing with the stoneware and porcelain stages further more recrystallizes the metakaolin into still more robust minerals including mullite.[six]
