Terra-cotta is a type of clay that has been used for centuries in pottery and building materials. It is often associated with a warm, reddish-brown color that is reminiscent of Mediterranean architecture. However, there are many other terms that can be used to describe this material. For example, "earthenware" is a broad term that includes terra-cotta, as well as other types of pottery that have been fired at low temperatures. "Clayware" is another synonym that can be used to describe any object made from clay, while "brick-red" or "rust-colored" are more specific descriptions of the color often associated with terra-cotta.
