CAN A PIECE BE REUSED TO MAKE INTO CLAY ONCE IT HAS BEEN FIRED?
Question: Once a piece has been made and fired is it possible to crush and make into clay again to remake if you don't like?
Answer: Unfortunately, the answer here is no. The reason is that once you fire a piece of clay chemical changes occur. You first are chemically firing out the water which cannot be replaced.
Second, if fired to what is called "maturity" you are actually "vitrifying" the clay particles. Put simply, this means that the clay particles melt partially and fuse together. Once this has been done there is definitely no going back.
You can always turn greenware back into clay. Greenware is clay that has been formed and dried, but has not yet been fired.
Hope that helps,
