You can fire clay anytime after it has been crafted.
As long as the clay has not been fired in the kiln, it can be recycled.
Clay is fired in a kiln.
Dry clay can be recycled by putting it in water. This will remoisten the clay and allow it to be kneaded and molded. Once clay has been fired it can no longer be recycled. Fired clay can be soaked a long time and will not dissolve.
Fired clay is not reversible; once it has been heated in a kiln, it undergoes a chemical transformation that permanently hardens it into a ceramic material. This process, known as sintering, removes moisture and alters the structure of the clay, making it rigid and unable to return to its original malleable state. While unfired clay can be reshaped or reused, fired clay cannot be reconstituted into its original form.

When clay has been fired and is a creamy white color, it is called bisque ware. Bisque ware is pottery that has been fired once and is ready to be glazed and fired again to achieve its final color and finish.

Clay can exhibit both reversible and irreversible properties depending on its treatment. When clay is wet, it can be molded and shaped, making it reversible; however, once it is fired in a kiln, it undergoes a chemical change that hardens it, making it irreversible. This transformation means that fired clay cannot return to its original plastic state. Thus, the reversibility of clay largely depends on whether it has been fired or not.

Of course not!
If it is earth clay, probably nothing. If you are talking about Play Dough, nothing. If the clay has been fired and has glaze on it, some glazes are toxic.
Malleable wax is a pliable material that can be shaped and molded before hardening. Unbaked clay is clay that has not been fired in a kiln, so it remains soft and can be reworked. Baked clay has been fired in a kiln, making it hard and durable. Metal can be shaped and molded when heated, but once cooled and hardened, it retains its shape.

Firing clay is when a clay is fired in a kiln, this is to make the clay stay strong.
