Is clay irreversible?
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.
What are malleable wax unbaked clay baked clay or metal?
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.
Is making bricks a physical change?
Yes, making bricks involves a physical change. The process typically includes mixing clay and water, shaping the mixture into bricks, and then drying or firing them in a kiln. While the physical properties of the clay are altered, such as its shape and hardness, the chemical composition of the materials remains the same, classifying it as a physical change.

Is fired clay reversable?
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.
Is porcelain a type of stone?
