It depends on what kind of clay it is, whether it be terra-cotta, stoneware, or porcelain. Each of these clays has different clay particle size. Also, it depends on how much water is in the clay. The more water, the more it will shrink in the firing process.
If I understand your question it sounds as if you have a clay and want to make something. It doesn't go into a normal oven, but a kiln. The temp in the kiln are much higher than what a kitchen oven can produce. The high heat turns the clay into a porcelain .
Yes I have red it pretty much every where but don't paint before putting it in
A glass kiln has heating elements on the top, as opposed to the ceramic kiln which has the heating elements around the sides. The glass kiln has molds for the glass to form to and the top heating elements aid in this sense. It's not the element placement as much as the program used. A glass kiln needs to go down slowly for annealing.
I would suggest any air dry clay because with polymer clay you would need to bake it and use tls instead of glue. You will need to wait longer for your decoden piece to dry but it's much safer than putting the thing you are goin to decoden in the oven.

It would depend on how hot the fire gets. If the fire burns really hot then the clay can actually melt and slump. I've seen wood firings where several pots were fired too hot and melted to the kiln shelf. It also depends on what kind of ceramic material is being burned. Stoneware can stand up to much higher temperatures than earthenware clay. But, I would say that if the whole house was left to burn with no interference then ceramic would not survive the fire no matter what type of ceramic it is.
Depends on your preheater, but in a modern preheater plant you will often feed 60% in the TAD and 40% in the kiln. KK
Before the invention of the rotary kiln, cement production was a much more laborious process. It was usually stirred continuously in a wheelbarrow or other receptacle.

Porcelain is a kind of high fire clay, and is safe and suitable in the oven. Glass meant to be used in the oven is also fired in a kiln and safe. There really isn't much difference between the two dishes and you should get the same results.
