Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.
All clay is a ceramic material, but there are other ceramic materials, as well. Glazes are also ceramic materials, because they permanently change during firing. Industrial ceramics include a range of materials such as silica carbide and zirconium oxide.here is commercial pottery or ceramics which are produced in factories, and there is studio pottery which is produced by individual craftsmen. You may also hear of  art pottery , which may be either produced commercially or by an individual craftsman.
