It depends on the clay. Different clays need different temperatures.
You can actually get clay that fires in an oven. It is not suitable for anything other than decoration but that would be the minimum "firing" temp for pottery. You can also do pit fires which are lowfire.
some samples
Thanks Thats All I wanted to know. Oh one more thing... I noticed that I have non typical oven :-) My oven has 300oC (temperature counter ends on 300 i guess that it can make some more heat ;-) )
That would be 572F and most ovens that I know of go to 500F.... still it would not do anything but dry out the pot on most clays potters use (600 is where you begin to get things going on I believe...)
Although the oven clay is not really clay I have been impressed with what can be done with it. I especially like the affect that mimics glass - I cannot remember the name of the technique but for glass you take and do layers of different colors of class (often pinching in the ball of glass on one layer to then give the next layer different depths of color. When you get enough layers of different colors and the glass is hot you have two people with an iron rod attached to both ends of the glass run like hell away from one another. This stretches the glass out to thin rods that can the be sliced and used to 'tile' a piece of glass that is then blown. It is much easier to do with the synthetic clay....
pulling cane
And what is the finished piece called? They used to do paperweights with them as well.... Looks kinda like an old fashion quilt.

not quite. you make a brick or rod of glass somehow. you can either build it up with rods, strips, frit, etc, then melt it together in a flame or kiln. that's called a cane. attach a punty or grab it with plier-like tools on each end. heat up in a flame and pull making it be very thin. pulling cane. you then take the long rod, cut it into slices (saw, nippers, glass cutter, etc). these slices are called millifiori. you then use these slices in making other objects (paperweights, bowls, etc).
As far as I can tell from a search on pulling cane the glass style that I'm talking about is called Millefiore or Murano glass. Thanks for the lead. DK
Not quite what? When I was a child they used to make quilts from pieces of fabric that were cut, shaped and formed around of all things on bottle caps. These were pieced together and looked just like the pieces of glass works I'm referring to that were around quite a bit at the same time.
For the glass pieces that I'm talking about the canes were cut into slices that were put together much like you would form a pattern for a quilt. This 'grid' of glass pieces had a liquid glass 'ball' (yes I'm making the jargon up because I can't remember what we called it) pressed onto it. You could then leave it as a solid piece (paper weight) or blow it out as a bowl, vase, etc.
