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.
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.
The raw materials used by potters typically include clay, water, and various minerals or additives depending on the desired properties of the final ceramic piece. These materials are combined, shaped, and fired in a kiln to create pottery.
