What kind of pottery is made from coarse baked clay?
Various types of clay are used.Earthenware tends to have larger amount of iron oxide. It can't be fired to very high temperatures as the iron oxide would act as a flux and the pottery would sag Stoneware can be fired to higher temperatures. It is opaque and fairly waterproof when fired.Porcelain can also be fired to high temperatures, it vitrifies and becomes very hard, even glassy.There are as many variations between clays as there are bags of clay, but most fall into these categories
Where do you place a piece of pottery when it is being fired?
When pottery is being fired it is placed inside a kiln. Most potters do two firings, one for bisqueware and a glaze firing. Bisqueware is pottery that has been fired to a temperature hot enough to not only evaporate any water in the clay, but also evaporate water at the molecular level thus changing the chemical structure of the clay molecules and creating the hard material you know as ceramic. After bisque firing, pottery is glazed and placed in another kiln. There are many types of glaze firings. Some are done with gas (reduction firing) and some firings are done with electric (oxidation firing). There are also unconventional methods of firing such as Raku, pit firing, and soda firing.

Why is clay used in pottery?
Soft clay must be used on a potter's wheel to create pottery, and then fired in a pottery oven ADDED: It's pretty much clay-ware by the definition of "pottery"! :-) It's used because it has particular qualities that allow it to be shaped and fused by heat to produce articles that are functional, decorative - or both - in their own characteristic ways.
Why do the potteries not make pottery?
Without more information about your question, it is hard to be clear about why potteries don't make pottery. If you are referring to a pottery wheel not correctly producing pottery, there may be an issue with the wheel's functioning or the material being used. The clay may not be the right consistency or of the right composition.

How were Mayan pots made?
First, they found clay by the rivers. Then, they dipped the clay in water to make it less tough and hard. The Mayans then carefully molded their pottery with their hands. They then let it bake in the sun so it would be hard and not brittle. When that was finished.. voila!That was how Mayan pottery was made.
