Crystalline ceramic materials are not amenable to a great range of processing. Methods for dealing with them tend to fall into one of two categories -- either make the ceramic in the desired shape, by reaction in situ, or by "forming" powders into the desired shape, and then sintering to form a solid body. Ceramic forming techniques include shaping by hand (sometimes including a rotation process called "throwing"), slip casting, tape casting (used for making very thin ceramic capacitors, e.g.), injection molding, dry pressing, and other variations. Details of these processes are described in the two books listed below. A few methods use a hybrid between the two approaches.

a discovery made thousands of years ago increased the usefulness of dried clay objects. Heating clay to about 1,000 celcius makes it harder and stronger. ceramics are hard, crystalline solids made by heating clay and other mineral materials to high ctemperturs
Wade Ceramics was created in 1867.
Usually ceramics is not transparent and glass is
Technically, glass is a kind of ceramic, but when most people talk about ceramics, they mean clay that has been made very hot to cause the particles to bond together, leaving little spaces between them. During this process, the crystal structure of the clay does not change, and the particles do not actually melt. Common silicate glass is made of silicon dioxide and some other minerals, and the process melts these minerals together into a non-crystalline structure. Silicate glass can be transparent, but clay ceramics are not. Ceramics that are not glazed or otherwise treated to make them waterproof can also absorb gas or liquid (like water) into the spaces between crystals.
ceramics is associated with pottery but not sinks
