Clay pot fired in a kiln physical or chemical?

The firing of a clay pot in a kiln involves both physical and chemical processes. The physical process is the application of heat to the clay, causing it to harden and form a solid structure. The chemical process involves the transformation of the clay minerals into a more stable crystalline structure through processes like dehydration and recrystallization.


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.


What will happen if you kiln fire beach sand on a low fire clay body?

Kiln firing beach sand on a low fire clay body may result in thermal expansion mismatches due to the different melting points of the two materials. This can lead to cracking and warping of the clay body during firing, potentially causing it to break apart. It is not recommended to mix beach sand with clay for this reason.
