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.
What happens to the clay in the kiln?
pottery Answer: you will find glass being fused or heated in kilns.
What are types of pottery?
Are you asking what kind of clay types there are? What can you make with clay? or what different processes there are for firing the clay?
Does ceramic shrink when it dries?
Yes any pottery and ceramic item made of clay shrinks in drying and each firing stage.
What activities can expose participants to lead?
These include making pottery or stained glass, refinishing furniture, doing home repairs, and using indoor firing ranges.
Is putting pottery in heated place a physical or chemical change?
It is a physical change

Is a forest fire a chemical reaction or reversible reaction?
Firing a forest is a chemical change because you change a wood into ashes and never reverse it back again
What evidence is there that the earths magnetic fields move?
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
What chemical compound make up pottery glaze?
Pottery glazes are typically composed of various chemical compounds, such as silica, alumina, fluxes (e.g. feldspar or boron), colorants (e.g. oxides or stains), and modifiers (e.g. clay or talc). The specific composition of a glaze depends on the desired effect and firing temperature, as different compounds contribute to qualities like color, texture, and durability.

How do you change your engines firing order?
You cannot change an engines firing order.
Is a piece of pottery an example of fossil?
No, a piece of pottery is not an example of a fossil. Fossils are the preserved remains or traces of ancient organisms, while pottery is a human-made object. Pottery is typically made by shaping and firing clay or other materials, whereas fossils are formed through the natural processes of fossilization.
