If your clay is moistened all over again, it'll over again come to be plastic. Once the clay is fired for the earthenware phase, a dehydration reaction removes extra drinking water from your clay, creating clay plates to irreversibly adhere to each other by using more powerful covalent bonding, which strengthens the fabric. The clay mineral kaolinite is remodeled into a non-clay content, metakaolin, which continues to be rigid and challenging if moistened all over again. Further more firing in the stoneware and porcelain phases additional recrystallizes the metakaolin into nevertheless stronger minerals for example mullite.[six]
