As the water is drawn into the clay body, the glaze particles are left behind on the surface. Generally, crazing is considered a glaze defect because the vessel can be significantly weaker than an uncrazed pot. Crawling crawling is caused by a high index of surface tension in the melting glaze. Shivering can be corrected by adding. As the ceramic cools, the glaze contracts more than the clay, resulting in stress and the formation of fine cracks. Craze lines can also harbor bacteria or germs. Glaze crazing occurs when a web of tiny cracks appears on the surface of a ceramic piece after firing.
